The first time I met Dr. Daniel M. Zimet, he told me the story of his best-ever handball match. His story changed my life, and it can empower investment leaders to improve the trajectory of their organizations. It goes like this… By the time the 1997 three-wall Nationals came around, Zimet had already lost eight times to his nemesis Kendall Lewis, a ranked professional handballer. “If you were to see us side-by-side, the results wouldn’t surprise you. Kendall was built like an NFL tight end. I’m scrawny and scrappy,” Zimet said. This fateful match started at five on a Saturday afternoon. The first game went the same way as many others between the two players. Zimet ground out bread-and-butter points while Kendall made spectacular shots. But unexpectedly, Zimet eked out a 21-20 victory in game one after an hour of play. Lewis found his rhythm in the second game and prevailed 21-7, sending the match into a tiebreaker.  As it started to get dark, the venue’s lights came on and the players passed the second hour of grueling play. The crowd swelled. The fans became so boisterous that the event director stopped matches in the adjacent courts. Those fans added to the ones already watching this incredible match. Beer was flying in the stands. Kendall served for the fourth time to win the match point. Trying something new, he hit an overhand serve. Zimet’s return was weak and short, a perfect opportunity for Lewis to hit a low-kill shot. More than 20 years later, as we sat in his office, Zimet recalled what happened next like it was yesterday: “I reached deep into my depleted well of strength and sprinted as fast as I could to the front of the court, where Kendall’s match-ending shot seemed to fall in slow motion. At full sprint and stretch, I caught up to the ball an inch from the ground and hit the perfect shot — a flat kill. I rolled over on the concrete to break my speed. On my knees, I squeezed both hands into fists and screamed at the top of my lungs. The crowd’s roar was so overpowering that I couldn’t hear my voice.” His voice trembled as he retold this story. I could swear his eyes grew watery. But what happened next is a bit strange. He told me the rest of the story nonchalantly. “He was down 9–10 and failed to score on his next serve. Then, Kendall served an ace.” “Wait, you lost?” I asked. “How was that your ‘best moment’? What about all your wins?” I couldn’t understand how a world-class athlete could be elated by defeat. But Zimet then explained his rationale: “Measurable goals can impede self-motivation. Those who focus on mastery — rather than on the scoreboard — are the biggest winners in the long run. That time, I played to the absolute best of my abilities.” This match changed Zimet. From then on, he knew he belonged amongst the best in the game. “Every victory stands on that match’s shoulders,” he told me. “That match, that point, and that loss solidified my quality as a player, a competitor, and a person, making it the most important moment of my career as an athlete.” Of course, he loves to win, but Zimet – a sports psychologist — defines success in terms only a sports psychologist could. He focused on mastery over ego, the importance of relationships and community (“The crowd’s roar was so overpowering that I couldn’t hear my voice”), the meaning of sport as a meritocracy, and the importance of engagement and flow. To him, all these concepts came together that day on the court. His theory became an epiphany for me. I asked myself: What if leaders could develop a similar mindset and apply it to their organizations? Zimet’s story was the spark that started the project that became my forthcoming book, The Psychology of Leadership, available for pre-orders. It put me on a path of discovery. I spent four years investigating new ways to apply psychology to leadership. I plowed through hundreds of books and articles in scientific psychology. What I learned has been life-changing and worth sharing with the world.  I will be discussing these concepts at CFA Institute Live 2025 in Chicago in May. In next week’s post, I will discuss the hidden trap sabotaging your decisions. source

“You cannot anticipate exactly how these risks or dangers are going to play out. . . . But we should be pretty assertive in insisting that we need certain principles, including enough capital buffers — that is, equity unencumbered by any kind of contingent debt or anything like that — that can really withstand shocks in the core of our financial system.” — Simon Johnson, Co-Chair, CFA Institute Systemic Risk Council (SRC) The effects of potential crises and dislocations on the global financial system and on systemic risk, in particular, can’t all be forecast in advance. The best we can do is prepare for a range of systemic risks and ensure that markets have the right infrastructure and regulatory frameworks in place to weather the storms.  In the case of the war in Ukraine and other geopolitical conflicts, that means understanding the consequences of sanctions, embargos, and potential tariffs and countering the spillover effects on energy, food, and other commodities markets. For financial institutions, that means enough liquidity to withstand unanticipated shocks. For stablecoins, cryptoassets, and other newer markets, it means having the regulatory oversight, authority, and mechanisms in place to protect investors. Simon Johnson, former IMF chief economist and co-chair of the CFA Institute Systemic Risk Council (SRC), thinks about issues like these every day. He sat down to talk about systemic risk and the many pressing challenges affecting global economies and the global financial system with SRC executive director Kurt Schacht, CFA, at the Alpha Summit GLOBAL by CFA Institute in May 2022. War in Ukraine What implications does the ongoing war in Ukraine have on systemic risk? “We are watching this very carefully,” Johnson said. “[You] have the Russians who are trying to drive up gas prices in Europe. They’ve actually been very successful in that. They’re trying to disturb and unbalance the global oil market — a bit more mixed results on that, but they’re definitely still having a go. And all of those things, of course, feed into inflation, particularly headline inflation. Food prices have been impacted, energy prices absolutely impacted.” Will the conflict threaten the solvency of financial institutions? “That is the question of the day and every day right now,” Johnson said. “The key is capital. How much equity do we have in the financial system as buffers against losses? That was the problem globally in 2008 and was a big recurring problem in Europe after 2010.” But there’s good news. The reforms instituted in the aftermath of the global financial crisis (GFC) in the United States and Europe were more effective than many people, Johnson among them, might have anticipated. “So banks are better prepared for unexpected shocks,” he said. “And unexpected shocks — well, we just had two big ones in the last two years basically.” “This is a big stress test,” Johnson continued. “COVID was a real stress test. Let’s agree on that. But COVID actually played out in some ways better and easier. There was a pretty unified and well-organized government response for a while on the economic dimensions at least. Now we’re dealing with something much more complicated, I would suggest, and likely more difficult.” Johnson has written extensively on how to respond to Russia’s invasion of Ukraine, whether in the form of sanctions, the oil embargo, tariffs, or other actions. He worries about Russia shutting down the grain and agriculture trade in the region. “This is another way they are malevolently putting pressure on the world,” he said. “And I think we need better coordinated, I would propose G7-led, responses to that economic issue, which is a massive overlay with national security considerations.” Climate Change as Systemic Risk What role if any should central banks play in addressing climate change risk? According to Johnson, there’s now a consensus in both industrial countries and emerging markets that climate change could impact the financial system either directly or indirectly through its economic impact. “I think that’s actually already decided,” he said. “I think central banks want to go there.” The question is how. “There is some ongoing debate about exactly what central banks should do — what instruments they have, what’s the appropriate scope for action. Is it a proactive thing directly to do with financing energy, or is it more about capital buffer and how do we calibrate that?” he said. “That’s a very active, somewhat technical discussion that doesn’t always come out clearly in the public context.” Johnson emphasized that part of the role of the SRC is to get involved and make sure its members understand the issues, that they are talking to the officials, and really engaging with them on those kind of technical but critical details. Johnson believes both the physical risks of climate change and the energy transition risks in reaching net zero are interconnected and systemic. “I think in the US military there’s a saying along the lines of ‘Plans are worthless, but planning is everything.’ I think that same thing goes for systemic risk,” Johnson said. “Because markets are going to go up, markets are going to go down. Financial institutions are going to fail. The questions are, Does that affect the core of the financing of your economy? Does it have spillover effects into energy prices, for example? Does that affect, in some destabilizing way, the macro economy? Those are the issues we have to keep at every day.” Stablecoins, Crypto Assets, and CBDCs The SRC has been outspoken about the need for regulatory action around “stablecoins” and issued a letter to the US Treasury and members of the Financial Stability Oversight Council (FSOC) in February 2022 urging action to “address the risks to U.S. financial stability posed by unregulated stablecoins.” The SRC recommended that FSOC designate stablecoins as systemically important payment, clearing, and settlement activities and asked FSOC member agencies to use their existing authorities to oversee and regulate stablecoin markets. Johnson pointed out that having some markets for assets that go up and go down is not by itself inherently systemic. But in the SRC’s view, if the public

“As we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say, we know there are some things we do not know. But there are also unknown unknowns — the ones we don’t know we don’t know.”   US Secretary of Defense Donald Rumsfeld during a Pentagon briefing We assume professional experts know a lot about their areas of knowledge whether in national security, investing, medicine, or other fields. But, as Rumsfeld’s comment highlights, “metaknowledge,” or awareness of the limits of your knowledge, is just as important as knowing what you know. Do professional experts have an edge over non-experts by having higher levels of metaknowledge? A new study sought to answer that question by conducting research with experts in the fields of climate science, psychological statistics, and investment. The researchers concluded that experts did tend to have higher metaknowledge than non-experts. For example, they were less overconfident overall but had more conviction in their correct answers than non-experts. However, experts were also more likely to exhibit greater confidence in their wrong answers compared to non-experts. Previous studies found cognitive biases among finance and medicine experts. For example, economists display overconfidence in their theories, despite a long history of incorrect forecasts. While touting the importance of decision analysis in general, investment professionals often fail to do so in practice. Yet, many maintain strong conviction in their sub-optimal conclusions. Alas, years of experience does not seem to ameliorate these tendencies. Medical professionals have exhibited similar patterns. In one study, physicians’ confidence in a diagnosis remained at 70%, even when they correctly diagnosed difficult cases only 5.8% of the time. Just as misjudgements can harm a medical patient, sub-optimal decision analysis can harm a client’s investment returns. Given the durability of certain cognitive biases, how can advisors de-risk decision-making by raising their metaknowledge? One way to do this is by leveraging individual investing talents within a structured team environment. This gives an organizational edge. Organizational edge is not merely about the sum of individual talents but also how these talents are structured, integrated, and leveraged. A well-designed organization optimizes team dynamics, encourages effective communication, and fosters a culture that supports decision-making aligned with its strategic objectives. Having the right environment and processes in place can amplify individual capabilities which are as essential to success as are market strategies. Bigger is not always better when it comes to investment teams. Having a large research investment team does not guarantee good decision making or sound judgement. In fact, it can add unnecessary complexity and inefficiencies into the investment process. Flatter organizations tend to do better. This may be due to more simplified structures. Leveraging the insights of research analysts alongside those of portfolio managers is the mark of skilled leadership and a supportive environment. Teams with diversity in education, experience, skills, and knowledge can add value to an organization through shared goals and open communication. Studies show that gender-balanced investment teams may have an increased potential to achieve superior risk-adjusted returns. A recent report by the CFA Institute Research and Policy Center offers a framework for improving gender diversity in the investment industry. Key Takeaway Confidence is a necessary but insufficient factor in long-term investing success. Raising the metaknowledge quotient of the investment team can help protect against the surprises that lurk in left-tail events and remain unknown, until they’re known. source

The surge of retail investor activity in public markets is a well-documented phenomenon. Digital brokerage platforms and online learning channels are the primary drivers. They often give users the illusion that they can compete with large institutional investors and capitalize on market volatility. Retail investors comprised 25% of total equities trading volume in 2021, which was nearly double the percentage reported a decade earlier, according to online investing platform Public. In February 2023, retail investors across online platforms set a new all-time high for weekly inflows, with $1.5 billion in retail assets pouring into the market in a single week, Public reports. Sadly but predictably, however, only a small minority of retail investors make money through day trading: between 10% and 30% every quarter. Yet, every day, hundreds of millions of dollars are invested through online trading platforms, including those that allow risky binary options trading. Many of these platforms appeal to the same human instincts as sports betting platforms, emphasizing the adrenaline of “winning” and “becoming rich,” as if day trading was a certified tool to make money. Scores of financial influencers (finfluencers) blast “magic” trading tricks on social media, further pushing uninformed retail investors to day-trade. Easy access to online platforms with limited controls creates an uneven playing field vis-à-vis institutional investors. Retail investors are in effect competing against professional institutional traders who have access to top research and data. The potential for an overwhelming amount of capital chasing the same opportunities in public markets, potentially exacerbating stock market bubbles, is the result, as we witnessed in the GameStop short squeeze. Private Markets Offer an Alternative Risk-Return Profile Private market opportunities offer an alternative risk-return profile that could benefit a retail investor’s portfolio through diversification. But these opportunities are often overlooked, and retail investors are underrepresented. Several factors create a barrier to private markets that is difficult for retail investors to cross. First, private offerings are only available to accredited investors, who meet certain  asset or income thresholds. Second, high minimum investment requirements are common for most private market opportunities, including private equity funds. These requirements run contrary to traditional portfolio allocation recommendations of 5% to 10% in alternative assets. Finally, a general lack of information and education about private markets perpetuates the myth that private market investments are inherently “riskier.” SEC Rules 506(b) and 506(c) severely limit access to private offerings, allowing access to only accredited investors and  a limited number of non-accredited. The SEC’s intention is to protect investors with limited financial knowledge or limited available assets to allocate to less liquid investments. Less-sophisticated investors are deemed to be more vulnerable in private markets due to the high level of customization of investment opportunities.  Unsophisticated investors are able  to access online trading platforms, however, including those that offer binary options. These platforms are built and advertised in the same fashion as sports betting sites. Investors on these platforms typically lose money, data shows, and odds are stacked against them in these markets, which  are characterized by massive information asymmetry. Are Public Markets Really Less Risky? Ultimately, the notions that public markets are inherently less risky or  that anyone with a laptop and an internet connection is a knowledgeable investor are misconceptions. Behavioral finance has already debunked the myth that human beings are rational investors. We know that public market bubbles are exacerbated by investor “heuristics.” Such bubbles may have become larger and more frequent since the increase in retail investor participation. Something also needs to be said about higher minimum allocations. While there are some private market investment vehicles with minimum investments as low as $25,000, most opportunities require investments in the range of millions of dollars. If a traditional portfolio allocates 10% to alternatives, an investor will have to hold substantial amounts of investable assets to access a single private market opportunity. It is hard to see how this does not limit opportunities for diversification. Private market investments, especially private credit, can offer returns that are not subject to daily market fluctuations, providing much-needed diversification in an investor’s portfolio. Private markets are more insulated from daily investor sentiment because their performance is driven by more fundamental factors. They present an opportunity for patient capital to be deployed to professionally sourced opportunities that are less correlated to public market oscillations. Education is Key In this post, I merely raise the question of whether the current regulatory framework is conducive to better consumer “welfare.” That is not to say that retail investors should be allowed to seamlessly access private markets. In fact, education is key. “An Introduction to Alternative Credit,” which I co-edited with Philip Clements for the Research Foundation, is a good primer on the credit side. Service providers that offer private investments should offer retail investors more transparency and more education. Ultimately, a more balanced investment strategy that includes private market allocations—subject to well-informed investor decisions—could potentially offer a more stable and diversified portfolio.

It’s easy to forget that the idea of investing in the entire market — passively and scientifically — was once heresy. But as listeners quickly learn in David Booth’s conversation with Larry Siegel on the Financial Thought Exchange, it was this very heresy that upended the investment industry over the last four decades. Booth, co-founder of Dimensional Fund Advisors (DFA), didn’t set out to change the world. In fact, he left academia precisely because he didn’t want to be the guy inventing new theories. His talent, he realized early on, was applying the breakthroughs others had already made. That insight, along with his time spent in the halls of the University of Chicago surrounded by future Nobel laureates, set in motion a movement that would redefine how portfolios are built, markets are understood, and investors are served. As the CFA Institute Research Foundation celebrates its 60th Anniversary, Booth’s story serves as a powerful reminder of what rigorous, applied research can achieve. The revolution in finance that he helped catalyze — rooted in empirical evidence, academic collaboration, and a deep respect for markets — mirrors the Research Foundation’s mission to advance the frontiers of investment knowledge. Booth’s conversation with Siegel exemplifies how research doesn’t just inform theory — it shapes industries, builds institutions, and transforms investor outcomes. With some help from our AI tools, I summarize some of the key talking points. But consider this to be a preview. There’s so much more — from Booth’s early brush with Milton Friedman to behind-the-scenes stories about building DFA and navigating decades of market change. Listen in for the full story: Part I and Part II. The Data That Changed Everything In the mid-1960s, the finance world was experiencing a paradigm shift. For the first time, thanks to advances in computing and newly available datasets from the Center for Research in Security Prices (CRSP), researchers could empirically test investment ideas. Booth, then a PhD student under Eugene Fama and a classmate of Roger Ibbotson’s, watched as the myth of consistent manager outperformance began to crumble under statistical scrutiny. Most investors didn’t know what the market returned, let alone how to beat it. When early data studies showed equities had historically delivered more than 9% annually, many were shocked. Trust departments at institutions couldn’t come close. Active managers were exposed. “We suddenly had a science,” Booth said. “We could test what worked and what didn’t.” And What Didn’t Work? Most of the Industry. What emerged from this upheaval wasn’t just a critique of active management but a roadmap for how to invest better: embrace the market, avoid unnecessary costs, and be flexible. Booth’s work at Wells Fargo, under the influence of pioneers like Fischer Black and Myron Scholes, gave him a front-row seat to the birth of index investing. But he also saw its shortcomings: mechanical rigidity, inefficient trading, and missed opportunities. “These were wild times, new ideas springing up everywhere.” So when Booth launched DFA in 1981 with Rex Sinquefield, they didn’t simply replicate the market, they reimagined how to access it. DFA’s breakthrough was to build broadly diversified portfolios, especially in underrepresented segments like small-cap stocks, but don’t be slavish to the index. Use data to guide structure, use judgment to trade intelligently. Booth called it “flexibility with discipline” — a philosophy rooted in academic evidence but tempered by market practicality. This was the birth of factor investing, though the term didn’t exist at the time. Academic studies (Rolf Banz on the small-cap premium, Fama and French on multi-factor models) provided the foundation. DFA built portfolios around size, value, and profitability long before those terms became industry buzzwords. Booth and Sinquefield weren’t chasing alpha. They were building access to dimensions of risk that had been shown to matter. Brutal Beginnings And yet, the early years were brutal. Small caps massively underperformed large caps through the 1980s. DFA’s flagship fund lagged the S&P 500 by hundreds of basis points per year. Most firms would have folded. DFA didn’t. Why? Because their belief wasn’t rooted in a bet; it was grounded in theory and data. “How do you survive?” Booth asked. “You go back to the fundamentals. You believe in diversification. You believe in markets.” Then came the second big reveal — the advisor channel. It would quietly reshape the industry from the ground up. But to hear how it unfolded, and who set it in motion, you’ll have to listen to the podcasts. Asked for advice to young professionals, Booth provided a framework: embrace uncertainty, find your comparative advantage, and build something you want to own if it works. He sees huge opportunity in financial advice, especially as technology lowers the cost of personalization. “People don’t want robo-advice,” he said. “They want to be heard. They want someone to help them connect life to money.” Booth’s story is a case study in how research, applied with conviction and creativity, can build enduring value. As CFA Institute Research and Policy Center marks 60 years of the Research Foundation — and 80 years of the Financial Analysts Journal — this conversation is a timely reminder of what that mission looks like in practice. The lessons may be rooted in the past, but their relevance for investors, advisors, and entrepreneurs today is undeniable. The best part? There’s still more to Booth’s story. Listen to the full conversation for the personalities, turning points, and off-the-cuff moments that didn’t make it into this summary. source

Artificial intelligence (AI) can improve our ability to identify and predict financial crises. A key innovation in AI is the ability to learn from data without being told exactly what to look for. Leveraging technologies like AI requires us to move away from traditional, subjective approaches and let the data tell us when conditions are ripe for a crisis. Grouping data points in a way that reveals patterns and insights we might not have noticed before is one method for identifying financial crises. This helps us get a better handle on what triggers these crises. At the University of Liechtenstein, Michael Hanke, Merlin Bartel and I are pushing this envelope further. In our recent  paper, we demonstrate how we redefined what we consider a financial crisis and used machine learning algorithms to predict banking crises in the United States. Our initial findings are encouraging, showing the potential to use AI to forecast financial downturns. Financial downturns can come in many shapes and sizes, like when a country cannot pay its debts, its banks face a rush of withdrawals, or the value of its currency plummets. These situations share a common thread: they stem from deep-rooted problems that gradually get worse over time. Eventually, a specific event might trigger a full-blown crisis. Spotting this trigger beforehand can be tricky, so it is crucial to keep an eye on these brewing issues. In simpler terms, these issues are like warning signs that hint at the chance of financial trouble ahead. Traditionally, experts used methods such as solving complex equations to guess whether a financial crisis might happen. This involves linking various factors to whether a crisis might occur, treating it as a yes-or-no question. Deciding what counts as a crisis often relies on expert judgment, highlighting the importance of how we define a crisis. Our approach is about fine-tuning this method to better match what we see happening in the real world. In modern tech talk, this is a bit like using a basic form of smart technology, where the computer is learning from a set of examples. This is a concept not too far from the early stages of what we now call AI. There are other, more creative ways to predict financial crises. For example, looking at how certain market prices move, which can hint at the likelihood of a country defaulting on its debt, offers a fresh perspective. To conclude, AI holds a lot of promise in refining how we understand financial crises. While grouping data points is just one example of what AI can do, these smart algorithms have a range of practical uses. Despite some current limitations, AI stands to offer significant advantages. It’s an exciting time to delve into the possibilities these technologies bring to the table.

Risk profiling is supposed to match an investor’s portfolio with both their ability and willingness to take risk. But “willingness” isn’t stable. It shifts with markets, headlines, and emotional reactions. Even the wording of a single survey question can change a client’s response before a market event ever occurs. That’s why advisors can’t stop at assessing risk preferences. To make risk profiling useful, they must also recognize and coach clients through the emotional biases that distort those preferences. I first encountered the critical distinction between risk tolerance and risk attitudes in Michael Pompian’s Behavioral Finance and Wealth Management. His explanation, that true risk tolerance is a stable, personality-based trait, while risk attitudes are volatile and emotionally driven, was both revelatory and practical. Yet it was only years later, after training in coaching, that I fully understood how emotional bias can be addressed, and how language can reshape what a client perceives as their “willingness” to take risk. Understanding the Trio: Risk Capacity, Tolerance, and Attitudes Most advisory frameworks adjust portfolio recommendations when there’s a mismatch between risk capacity (what the investor can afford to lose) and risk tolerance (what they’re emotionally comfortable withstanding). And here’s where it gets nuanced. There is a distinction between risk tolerance and behavioural risk attitudes. Both combine to determine risk appetite and yet there are essential differences: Risk Tolerance: A client’s stable preference for risk. It reflects the client’s enduring preferences about risk, often grounded in experience, values, and life stage. Behavioral Risk Attitudes: Unstable and highly context-dependent. They reflect short-term reactions to volatility, recent losses, or market headlines. While real, they are often poor guides for long-term decisions. When risk appetite falls short of risk capacity, the advisor’s job is not merely to reduce exposure. It’s to understand and address the emotional triggers that might be contributing to that low risk appetite. Allowing these unstable attitudes to dictate portfolio design risks producing an emotionally “comfortable” solution today that fails the client in the long run. Coaching Clients Through Common Emotional Biases Advisors often see the same emotional patterns play out when markets shift. Here are some of the most common biases and ways to reframe the conversation so clients can stay grounded in their long-term strategy. Loss Aversion Clients often say: “I can’t afford to lose anything right now,” or “I should pull my money out until things calm down.”A more helpful frame: The real risk isn’t just losing money, it’s missing the growth that secures future goals. The question becomes, “Are you trying to avoid short-term discomfort, or are you aiming for long-term financial security?” Overconfidence Clients may say: “I’ve got a good feeling about this sector.”A more helpful frame: A strong instinct deserves a strong process. Even good calls benefit from strategy. The question is, “What would this decision look like if we stripped out the emotion and focused only on the data?” Self-Control Bias Clients may say: “I know I should invest more, but I just haven’t gotten around to it.”A more helpful frame: “You clearly care about your financial future. How does delaying investing align with that priority?” Status Quo Bias Clients may say: “Let’s leave things as they are for now.”A more helpful frame: Sometimes standing still is the riskiest move. Ask, “What happens if nothing changes? What opportunities are lost by waiting?” Endowment Bias Clients may say: “I’ve had this stock for years, it’s been good to me.”A more helpful frame: “If you didn’t already own it, would you buy it today?” Explain that honoring past success might mean taking profits and reinvesting wisely, rather than holding on out of habit. Regret Aversion Clients may say: “What if I invest and the market drops tomorrow? I don’t want to make a mistake I’ll regret.”A more helpful frame: Diversification helps protect capital while still moving forward. “Think of it this way: refusing to plant seeds because it might not rain tomorrow means missing an entire growing season.” Conclusion Advisors today must do more than understand markets; they must help clients navigate their own internal markets. That means spotting biases such as: Loss aversion: reframing fear of short-term loss into focus on long-term growth. Self-control bias: helping clients act on their stated priorities. Overconfidence: turning instinct into process. Status quo bias: showing when inaction is the riskier move. Endowment bias: challenging attachment to legacy holdings.. Regret aversion: helping clients move forward despite uncertainty. Providing behavioral finance resources can help, but the greatest impact comes from the financial advisor who can respond in real time with empathy and perspective. Emotional biases are not flaws to eliminate; they are facts of human nature. The difference lies in whether those biases dictate portfolios or whether advisors coach clients to see beyond them. By aligning risk attitudes with true risk capacity, advisors can help clients become resilient investors rather than reactive ones. source

Since Harry Markowitz developed modern portfolio theory’s mean-variance optimization (MVO), financial advisors and wealth managers have been confronted with a crucial question: What is the relative importance of risk tolerance (the investor’s attitude toward risk) compared to risk capacity (the investor’s ability to endure negative outcomes)?  I must confess that I have been perplexed by this question for decades. My frequent co-author, Paul Kaplan, and I believe we have solved this 50+ year conundrum using an expanded MVO optimization model called net worth optimization (NWO).  I plan to discuss our findings on my panel at CFA Institute LIVE 2025 in Chicago in May. How did we get here? The goal (objective function) of mean-variance optimization is to maximize the expected return of a portfolio, minus a personalized penalty for the expected risk (variance) of the portfolio. Personalized penalty is the investor’s risk tolerance coefficient multiplied by the variance of the portfolio. In MVO, the “risk tolerance” coefficient is a single number reflecting the rate at which the investor is willing to trade off more risk in pursuit of more expected return. Knowing the investor’s risk tolerance coefficient allows you to solve for the corresponding MVO efficient portfolio. In the economics literature and the works of Nobel Prize winners like Paul Samuelson, risk tolerance is clearly related to the investor’s attitude toward risk, not risk capacity. Advisors frequently have a deep understanding of their clients’ situations. This might include information on additional accounts, spousal assets, compensation information, mortgage payments, etc. Some clients may be very comfortable with risk, but with little capacity for adverse outcomes given their circumstances. While other clients are extremely uncomfortable with risk but can tolerate adverse outcomes with little impact on their financial well-being. Advisors find themselves navigating what has been a highly subjective risk tolerance (attitude) versus risk capacity conundrum. Two Approaches to Risk Capacity Pragmatically, there have been two approaches that explicitly focus on risk capacity. The first approach is a common feature of the “scoring” component of risk tolerance questionnaires. When scoring the responses to a risk tolerance questionnaire, there are frequently two scores: a risk tolerance score and a time horizon score. The time horizon score serves as a crude proxy for the investor’s capacity to take on risk that limits which portfolios are deemed suitable.  The second approach is probably less known to practitioners but prevalent in the practitioner-oriented literature. This approach is best represented by the “discretionary wealth hypothesis” primarily put forth by Jarrod Willcox.[1] In these types of approaches, the investor’s attitude toward risk is discounted or ignored, and financial ratios like the ratio of assets-to-liabilities are used as the primary factor to estimate a so-called “risk tolerance coefficient. I use quotes to distinguish this from the economic definition of risk tolerance as an attitude. Net Worth Optimization (NWO) In our 2024 CFA Institute Research Foundation book, “Lifetime Financial Advice,” Kaplan and I put forth NWO. It is a significant extension of MVO. NWO includes all of the investor’s assets and labilities in the optimization, especially human capital, and it optimizes the investor’s holistic economic balance sheet. An investor’s economic balance sheet includes all his or her assets — home, land, collectables, and all financial assets. Most importantly, the economic balance sheet includes the capitalized value of the investor’s lifetime of earnings — human capital. For many people, the mortality weighted net present value of all future labor income, including deferred labor income in the form of defined benefits and social security, is their single largest asset. The lifetime of cash flows stemming from human capital is frequently reminiscent of the cash flows you would receive from a large, inflation-linked, long-duration bond. Others have less steady human capital that might resemble a stock/bond mix. On the right-side of an economic balance sheet, we all have ongoing expenses, such as rent, a mortgage, insurance, medical costs, and food. While these may not be legal liabilities, these expenses are often inescapable. Collectively, their capitalized values form what we think of as the investor’s nondiscretionary consumption liability.  Just as a balance sheet is an important indicator of a corporation’s financial health, a holistic individual economic balance sheet is an excellent indicator of the investor’s overall financial health and capacity for taking on risk. The difference between the total value of all assets and all liabilities is net worth. Hence the term net worth optimization or NWO.  NWO includes all the major economic balance sheet entries. Nontradable entries — the investor’s human capital and nondiscretionary consumption liability  —  are included in the optimization, although the optimizer cannot change the net present value of either. These nontradeable assets are modeled as portfolios of asset classes, which enable us to derive proper market-based discount rates and understand how they interact with the rest of the balance sheet. Imagine a 45-year old pharmaceutical scientist with a base salary of $200,000, adjusted each year for inflation, who receives $100,000 nominal restricted stock units with a five-year vesting schedule who also expects to receive approximately $25,000 per year from social security starting at age 65. One could model this person’s human capital as nearly 2/3rds long-duration-inflation-adjusted corporate bonds with a duration corresponding to the 20 years of cash flows, and nearly 1/3rd mid-cap stocks (reflecting the size of the company). You could refine the 1/3rd mid-cap stocks by modeling them based on the pharmaceutical sector or even using the specific stock in question. The current net present value of social security isn’t worth that much today, but it too should be accounted for properly. The expected returns on each form the basis for a weighted average cost of capital for calculating the value of the scientist’s human capital.  The capitalized value of the investor’s nondiscretionary consumption liability, which is somewhat like issuing a long-duration-inflation-linked bond with outgoing coupon payments, is included as a nontradable negative holding in the optimization. Then in the presence of nontradable assets and liabilities NWO determines the optimal asset allocation for the investor’s tradable

Factor selection is among our most important considerations when building financial models. So, as machine learning (ML) and data science become ever more integrated into finance, which factors should we consider for our ML-driven investment models and how should we select among them? These are open and critical questions. After all, ML models can help not only in factor processing but also in factor discovery and creation. Factors in Traditional Statistical and ML Models: The (Very) Basics Factor selection in machine learning is called “feature selection.” Factors and features help explain a target variable’s behavior, while investment factor models describe the primary drivers of portfolio behavior. Perhaps the simplest of the many factor model construction methods is ordinary least squares (OLS) regression, in which the portfolio return is the dependent variable and the risk factors are the independent variables. As long as the independent variables have sufficiently low correlation, different models will be statistically valid and explain portfolio behavior to varying degrees, revealing what percentage of a portfolio’s behavior the model in question is responsible for as well as how sensitive a portfolio’s return is to each factor’s behavior as expressed by the beta coefficient attached to each factor. Like their traditional statistical counterparts, ML regression models also describe a variable’s sensitivity to one or more explanatory variables. ML models, however, can often better account for non-linear behavior and interaction effects than their non-ML peers, and they generally do not provide direct analogs of OLS regression output, such as beta coefficients. Why Factors Should Be Economically Meaningful Although synthetic factors are popular, economically intuitive and empirically validated factors have advantages over such “statistical” factors, high frequency trading (HFT) and other special cases notwithstanding. Most of us as researchers prefer the simplest possible model. As such, we often begin with OLS regression or something similar, obtain convincing results, and then perhaps move on to a more sophisticated ML model. But in traditional regressions, the factors must be sufficiently distinct, or not highly correlated, to avoid the problem of multicollinearity, which can disqualify a traditional regression. Multicollinearity implies that one or more of a model’s explanatory factors is too similar to provide understandable results. So, in a traditional regression, lower factor correlation — avoiding multicollinearity — means the factors are probably economically distinct. But multicollinearity often does not apply in ML model construction the way it does in an OLS regression. This is so because unlike OLS regression models, ML model estimations do not require the inversion of a covariance matrix. Also, ML models do not have strict parametric assumptions or rely on homoskedasticity — independence of errors — or other time series assumptions. Nevertheless, while ML models are relatively rule-free, a considerable amount of pre-model work may be required to ensure that a given model’s inputs have both investment relevance and economic coherence and are unique enough to produce practical results without any explanatory redundancies. Although factor selection is essential to any factor model, it is especially critical when using ML-based methods. One way to select distinct but economically intuitive factors in the pre-model stage is to employ the least absolute shrinkage and selection operator (LASSO) technique. This gives model builders the facility to distill a large set of factors into a smaller set while providing considerable explanatory power and maximum independence among the factors. Another fundamental reason to deploy economically meaningful factors: They have decades of research and empirical validation to back them up. The utility of Fama-French–Carhart factors, for example, is well documented, and researchers have studied them in OLS regressions and other models. Therefore, their application in ML-driven models is intuitive. In fact, in perhaps the first research paper to apply ML to equity factors, Chenwei Wu, Daniel Itano, Vyshaal Narayana, and I demonstrated that Fama-French-Carhart factors, in conjunction with two well-known ML frameworks — random forests and association rule learning — can indeed help explain asset returns and fashion successful investment trading models. Finally, by deploying economically meaningful factors, we can better understand some types of ML outputs. For example, random forests and other ML models provide so-called relative feature importance values. These scores and ranks describe how much explanatory power each factor provides relative to the other factors in a model. These values are easier to grasp when the economic relationships among the model’s various factors are clearly delineated. Conclusion Much of the appeal of ML models rests on their relatively rule-free nature and how well they accommodate different inputs and heuristics. Nevertheless, some rules of the road should guide how we apply these models. By relying on economically meaningful factors, we can make our ML-driven investment frameworks more understandable and ensure that only the most complete and instructive models inform our investment process.

The past week marked a watershed moment for the eurozone, potentially signaling a fundamental shift in European economic policy. The coalition set to assume power in Germany  announced a massive fiscal package — ranging from 12% to 18% of GDP — which includes the creation of a €500 billion infrastructure fund and the relaxation of debt constraints on defense spending, representing a break from its traditional Exportweltmeister model. The Germans are having a “Jesus moment,” recognizing the need to shift from being a capital exporter — Exportweltmeister — to prioritizing domestic investment. This marks the beginning of a macroeconomic regime change, with EUR/USD acting as a key transmission mechanism. Betteridge’s Law of Headlines suggests that if a news article poses a question in its headline, the answer is typically “no.” Similarly, the placement of the question mark in the title of the article I wrote for Enterprising Investor in September 2022, “Is the Euro Uninvestable? The FX Question du Jour,” was intended to emphasize that uninvestable is a transitory term. Standing here today, one might be forgiven for thinking that Friedrich Merz, Germany’s Chancellor-in-Waiting, had my article conveniently pinned alongside The Draghi Report on EU Competitiveness on his policy board. More likely, of course, it’s a case of aligned thinking — reinforced by the huge wake-up call from Trump 2.0. The article I wrote back in 2022 also argued that the European Central Bank (ECB) should do away with the Atlas Syndrome of assuming the role of a fiscal authority and allow for market-driven price discovery in EUR-denominated bonds. That shift is now taking place. The ECB has jettisoned the Asset Purchase Program (APP) and the Pandemic Emergency Purchase Program (PEPP) and is currently on the path of Quantitative Tightening (QT). It’s very encouraging to see that the phrase “whatever it takes” is now coming from Germany’s Chancellor-in-Waiting rather than the President of the ECB. As Lenin famously said, “There are decades where nothing happens; and there are weeks where decades happen.” While this quote may be overused, it certainly justifies being invoked considering the magnitude of the market moves we saw last week. Bund yields saw their most significant moves last week since the fall of the Berlin Wall, with the 10-year UST-bund spread (US Treasury vs. German bund) compressing by around 44 basis points, bringing us full circle to relative asset pricing and the Portfolio Balance Approach as key determinants of EUR/USD performance. It’s no surprise, then, that EUR/USD surged from the 1.04 to the 1.08 handle last week. With a greater focus on domestic investment, the eurozone’s net international investment position (IIP) surplus should shrink and possibly even turn into a deficit. Of course, there’s many a slip between the cup and the lip. The fiscal package must pass through both the Bundestag and Bundesrat. And Germany’s deep-rooted Schwarze Null (black zero) culture of maintaining a balanced budget must be overcome at multiple levels. Nonetheless, market expectations are now aligned with the idea that Germany has truly reached an inflection point. Year-to-date, a notable divergence in trajectories has emerged with US and German yields, with US yields declining (10-year UST yield down by around 30bps) while bund yields are rising (10-year bund yield up by around 50bps), influencing cross-border portfolio rebalancing and EURUSD performance. On the other side of the pond, we are reminded to take President Donald Trump seriously but not literally. However, for market participants, this translates into heightened uncertainty. Recent academic literature on financial markets and decision-making in general emphasizes the distinction between risk and uncertainty. Risk arises in situations where outcomes and probabilities are well-defined. Uncertainty and ambiguity, on the other hand, refer to situations where outcomes and probabilities are unclear or unknown. These ideas, first formulated by thinkers like Frank Knight and John Maynard Keynes about a century ago, have only been formally detailed in academic literature over the past thirty years or so. They are particularly relevant in the Trump 2.0 era, which is beginning amid deep uncertainty and ambiguity. Trump’s “break first, ask questions later” approach to government spending and the persistent policy uncertainty surrounding tariffs is fueling concerns over growth and employment. These topics, of course, warrant a more detailed article on uncertainty versus risk , one that would also likely include the word uninvestable followed by a question mark. Summary The impetus in Germany to drive a fiscal policy pivot, set against the backdrop of the ECB’s ongoing normalizing of monetary policy, has fueled historic market moves. Last week, bund yields experienced their most significant shift since the fall of the Berlin Wall, with the 10-year UST–bund spread compressing by 44 basis points and EUR/USD surging from 1.04 to 1.08. As Germany recalibrates toward domestic investment, the eurozone’s net international investment position (IIP) surplus could shrink or even turn into a deficit. Germany’s political clarity in enacting policy change — despite the challenge of breaking from the black zero culture — stands in contrast to policy uncertainty across the Atlantic. With the return of Trump-era unpredictability — marked by policy ambiguity and a “break first, ask questions later” approach — investors are grappling with a landscape where risk and uncertainty blur. Amid the evolving dynamics on both sides of the EUR/USD equation, investors must weigh the potential for long-term transformation against short-term noise and consider whether this marks a trading regime with some legs or just another chapter in market volatility. source
