Alpha Exchange

Welcome to Episode 250 of the Alpha Exchange. To celebrate the milestone, I asked my dear friend, Jon Kalikow, to host the conversation, switching seats and having me as the guest. I launched the podcast in 2018 with a simple idea: to create space for long-form conversations that explore how market practitioners think about risk. Rather than focusing on predictions, the goal has always been to understand frameworks—how investors process information, respond to uncertainty, evolve through cycles. In this episode, we also explore some of my own thinking on risk. Here, I outline a simple framework built around four categories: economic, monetary, financial, and geopolitical. While distinct, these risks are deeply interconnected and understanding how they interact is critical in assessing market outcomes. Today’s market dynamics are fascinating in this context. We close the discussion with a look ahead—toward expanding the Alpha Exchange platform through live events, educational initiatives, and continued conversations that emphasize intellectual honesty, humility, and the ongoing exchange of ideas. I feel as convicted as ever about the business model which aims to create value through engagement. I hope you enjoy this episode and appreciate your ongoing support of the Alpha Exchange.

The “risk-free” rate figures prominently in how we’ve all been taught the foundations of finance. To price a security, start with the asset that is the safest and soundest and then add compensation for bearing uncertainty. It has always been self-evident that the global risk-free benchmark was the Treasury market. Deep, liquid and viewed as default free, US government bonds have been the recipient of capital during times of stress. And the reason is that the US has long been viewed as not just the world’s strongest economy but also a stabilizing force in global affairs. In this discussion, and with the help of four recent expert guests on the Alpha exchange, I argue that this is changing and the US is now becoming a chief source of risk. In the process, the Treasury market may be losing one its most important characteristics: the insurance feature. That is, its capacity to be durable to and even benefit from market shocks. We’ve all got to be asking, “how can US government bonds be a shock absorber when the US government is the source of the shock?” The implications for asset prices that result from a less stable US are significant and there are important questions to consider. I hope you find this discussion useful.

Kris Abdelmessih, author of the MoonTower Substack and founder of the options analytics firm MoonTower.ai., has spent years thinking about option pricing, volatility regimes, and the mental math traders use to translate volatility into price. In this context, it was great to welcome him back to the Alpha Exchange to explore his thought process. We begin with developments in commodity markets, particularly crude oil, and silver, where geopolitical tension and speculative flows have led to sharp changes in volatility surfaces. Kris explains how option skew in underlyings like oil can reprice rapidly during shock events, leading to inverted termstructure and a well bid call skew. These dynamics create unusual behavior in vertical spreads and probabilities implied by option prices. Kris describes how the relationship between spot moves and volatility changes across market environments, emphasizing that traders must continually recalibrate their models. What appears to be a stable relationship—such as the familiar beta between the S&P 500 and the VIX—can shift quickly depending on positioning and market structure. A major focus of our conversation is on the mental math traders use to interpret option prices without relying on models. Kris walks through several shortcuts that allow traders to move quickly between volatility, straddle prices, and probability estimates. These approximations help traders identify when prices look unusual and whether options markets imply probabilities that diverge from other markets. Finally, we discuss the work Kris is doing on financial education. Inspired by teaching his own children about investing and compounding, he has begun running small classes for students and sharing the materials publicly. The goal is simple: introduce younger investors to concepts like time value of money and long-term compounding earlier in life. I hope you enjoy this episode of the Alpha Exchange, my conversation with Kris Abdelmissih.

As Chairman and CEO, Zach Buchwald leads Russell Investments, a firm overseeing $370bln in client assets and celebrating its 90th anniversary in providing portfolio management services to institutions and individuals. Zach details the open-architecture model utilized at Russell, explaining how portfolios are constructed by combining best-of-breed managers and strategies across asset classes. He shares how these portfolios are managed through an outsourced chief investment officer framework, providing institutions with integrated portfolio construction, manager selection, and risk management. A central theme in our discussion is retirement, a large focus at Russell on behalf of its client base. Zach highlights the long-term shift from defined benefit pensions to 401(k) plans, and the structural and behavioral challenges individuals face in saving for retirement and the growing responsibility they now bear in planning. We discuss the power of compounding, the importance of staying invested through market volatility, and the role that portfolio design can play in helping investors avoid costly behavioral mistakes. While the 401(k) structure can work well when participants save early and remain invested, Zach notes that many Americans have not accumulated the assets necessary for retirement and that compounding requires both time and consistent exposure to the market. Default investment options, diversified portfolios, and disciplined asset allocation can help individuals remain invested through periods of volatility and capture the long-term growth of capital markets. I hope you enjoy this episode of the Alpha Exchange, my conversation with Zach Buchwald.
