RoR: Reflections on Risk

In this discussion, I share my thoughts on the backdrop for both SPX realized and implied volatility, as I explore the question of whether there is value in optionality. We have 3 things going in terms of realized vol at the index level. It’s low, it’s especially low on SPX down days, and it’s remarkably stable. My take is that the combination here can play tricks on how we think about risk. We are prone to letting our guards down. Next, I share a 5-part framework for addressing the question, “is insurance worth it?”. I find that certain proxy hedges like HYG provide excellent value at current ultra-skinny option premium levels. Next, I review the GOAT (Great Opportunities and Threats) portfolio which overlays gold and bitcoin as diversifying assets and index put spreads as insurance on a base portfolio that is long the SPX. The risk-return characteristics of the GOAT are decidedly better than those of the SPX in 2025. I also explore the pricing of SPX vol skew and how it is a headwind for collar hedging trades. Lastly, the topic of correlation is on my mind, especially as it is an input into structured derivatives trades that often cost too much. I hope you enjoy the discussion and find it useful. Have a great week.

On this episode of the Alpha Exchange, I had the pleasure of reconnecting with Ken Rogoff, Professor of Economics at Harvard and former Chief Economist at the IMF. In our conversation, we explore themes from his latest book, Our Dollar, Your Problem, a valuable retrospective, and analysis of the rise of the U.S. dollar as the world’s reserve currency and the vulnerabilities that accompany it. In our discussion, Ken reflects on the privileges America enjoys from dollar dominance, namely lower borrowing costs, financial system centrality, and sanction power—while warning that such advantages are not guaranteed forever.We also explore the lessons from past debt and currency crises and the fragility of fixed exchange rate regimes. Here Ken shares firsthand experience as a policymaker who was among those whose advice was sought for how to address many of the prominent FX vol episodes of the 1990’s.We turn to the main point of his book – that there are risks that come with assuming low interest rates will persist indefinitely and that our policy instability may be quietly undermining the dollar’s status as the reserve currency. Ken underscores that debt sustainability is as much about politics as economics, and that weakening of central bank independence may threaten the dollar’s safe-haven role. The main message: periods of calm often mask deep vulnerabilities and complacency about fiscal deficits, global dollar reliance, and policy credibility can quickly give way to instability.I hope you enjoy this episode of the Alpha Exchange, my conversation with Ken Rogoff.

It was a pleasure to welcome Kris Kumar, founder and CIO of Goose Hollow Capital, back to the Alpha Exchange. Kris presents a compelling argument that traditional economic frameworks centered on consumption are becoming obsolete as AI-driven capital expenditure emerges as the dominant growth engine. With companies spending $400 billion annually on AI infrastructure, he contends we're witnessing a fundamental shift from consumption-led to investment-led economic dynamics, requiring investors to recalibrate how they analyze market drivers and policy transmission mechanisms.Kris draws parallels between current AI investment patterns and historical tech bubbles, noting critical differences in financing structures that could alter unwind scenarios. He explores the unique challenges facing monetary policymakers as AI disrupts labor markets while tariff policies create inflationary pressures, potentially rendering traditional Fed tools less effective. The discussion also covers emerging market opportunities, particularly in Latin America, where countries benefit from AI-related commodity demand while offering superior real interest rates.I hope you enjoy this episode of the Alpha Exchange, my conversation with Kris Kumar.

As the summer winds down, and there’s so little daily motion in the SPX, the realized vol spike of April feels further in the rear view. I often suggest that periods of calm in the market can cloud our thinking about risk. Sometimes markets get caught in low vol moods and this is one of them. But low realized volatility should not be viewed as an all clear. A good case can be made that the backdrop is becoming definitively worse. I argue that the price of insurance is a good deal versus the totality of risks. Options are valuable in light of a building of uncertainty in the economy, in Fed policy, in tariffs, in US debt, and in a dangerous escalation in not just global affairs but in the US political civil war.

On this episode of the Alpha Exchange, I was joined by Ben Hunt, Co-founder and CIO of Perscient. Ben has built his career around one powerful idea: that the stories we tell—whether in politics, markets, or everyday life—shape our behavior far more than we realize. In the mid-2000s, entering Wall Street from outside its traditional ranks gave him a rare vantage point. He wasn’t steeped in the bullish narrative flow that dominated the industry. With an outsider’s perspective—and an ability to read the “language” of mortgage-backed securities—he was able to see flaws at the heart of a $10 trillion asset class well before the global financial crisis hit.In our conversation, we explore how understanding narrative structure can illuminate risk in ways models cannot, and why being outside the story sometimes lets you see it most clearly.  In this context, we chat as well about Ben’s creation of the Epsilon Theory, a widely read exploration of how narratives drive markets. I have personally found his writing thought provoking. On markets, Ben is not optimistic that our political system is up for the challenge of reigning in the unwieldy debt and sees the potential for some combination of higher rates and a lower dollar as a result. Today, through Perscient, a venture he co-founded, Ben is applying AI-driven tools to map and measure narratives in real time, helping investors see the hidden storylines moving markets.I hope you enjoy this episode of the Alpha Exchange, my conversation with Ben Hunt.

On my mind is correlation. There are plenty of financial market correlations, both implied and realized. In equities, we talk a good deal about the correlation implied by the relationship between S&P 500 index implied vol and the implied vol on the stocks within the index. That’s been low, to put it mildly. How about the correlation between the dollar and SPX? A signature aspect of the recent risk event was a weaker dollar, even as rates rose and the VIX rose while the SPX swooned.A correlation that gets little attention is that between an asset and its implied volatility. We know that - with only rare exceptions, when the SPX rises, the VIX falls. The correlation runs deep, about negative 80% or so. But for select other assets - and this is the main point of my little talk here - the correlation between the price and the implied volatility - is often actually positive. We call them SUVU, “stock up, vol up” assets. SUVU is that compelling financial trait of an asset that leads to substantial option trading volume as well as significant "derivative" ETF assets under management.Over the course of 20 minutes, I walk through how the option market pricing consequences of these assets with unique return distributions. I hope you enjoy the discussion and find it useful.

Greetings and salutations loyal listeners, welcome to what promises to be another exciting addition to our Sayings on Vol and Risk. To set the table, last year, I did a 5-part series with 25 Sayings. These are concise statements I’ve wound up using many times over during the course of my career to help myself and others think about market risk. These pitchy proverbs are market maxims that explore the drivers of unanticipated change in asset prices.   With the first 25 saying completed in 2024, I recently added 5 new ones, getting us to 30. This podcast gets us to 35 in total. Hope you enjoy and find interesting. 31. “Risk management suffers from a failure of imagination.”32. “Markets are a never say never business.”33. “Broken markets break down.” ~ Mike O’Rourke, Jones Trading34. “This is not your father’s ETF market.”35. “Doubt is not a pleasant condition, but certainty is an absurd one.” ~ Voltaire

Today’s world of ETFs and mutual funds increasingly features new flavors, a popular one of which is derived from embedding optionality. There are plenty of ways in which one might contemplate risk managing and shaping the distribution of equity returns using options. Common strategies like overwriting create income, but limit upside. Others like the zero cost collars create both upside and downside guardrails on returns. These strategies can be back-tested. Because they also exist in the market, with more than $200bln in AuM, the performance of the funds can be evaluated as well. With this in mind, it was a pleasure to welcome Dan Villalon, Global Co-Head of Portfolio Solutions at AQR Capital Management, back to the Alpha Exchange. Dan walks us through the findings from his research, published in a two-part series on the AQR website. In these notes, Dan dissects the drawdowns and returns across these funds. The findings are rather striking: across a wide sample of buffered funds and option-based strategies, very few delivered both higher returns and smaller drawdowns. In fact, most underperformed their beta-adjusted benchmarks on both fronts—meaning they not only lagged in returns but also failed to meaningfully protect against losses in periods like the COVID crash, the 2022 inflation-driven drawdown, and the volatility of early 2025. Even strategies designed explicitly for downside protection often fell short when it mattered most. I am a big believer in option strategies and in the value of the SPX options market as a vehicle to transfer risk. These results were a surprise to me.Dan outlines three key drivers: the persistent cost of buying options, the structural frictions involved in implementation, and the surprisingly high management fees for such rules-based products. Dan also introduces a more behavioral theory—what he calls the "placebo effect": the idea that investors feel safer simply because they're told they’re protected, even when the data shows otherwise. I hope you enjoy this episode of the Alpha Exchange, my conversation with Dan Villalon.

With nearly three decades at BlackRock, Mitch Garfin brings a deep well of experience to his role as Co-head of Leveraged Finance, overseeing high yield and leveraged loan strategies for the firm. In this episode, we explore the evolution of the credit landscape — from structural shifts in the high-yield market that leave indices of higher credit quality to managing risk in a world of tight spreads but always shifting macro narratives.Mitch shares how his team navigates dispersion, with recent focus on considering the implication of tariffs on different sectors. His team positioned for tariff-related volatility by reducing exposure to sectors like autos and consumer products perceived as most exposed to trade policy risk. Conversely, Mitch saw better value in the tech and insurance sectors.Next, we discuss advancements in trading technology and the implications for liquidity. Here, he argues that the electronification of credit markets and the growth in portfolio trading is having profound impact on risk transfer, reducing frictions and transaction costs. In the process, he shares how his team leverages tools like ETFs and the CDX product to manage exposure.I hope you enjoy this episode of the Alpha Exchange, my conversation with Mitch Garfin.

In 2024, I did a 5-part podcast series called “25 Sayings on Vol and Risk”.  These are observations I’ve found do a nice job of describing how markets work, or perhaps better said, how markets sometimes fail to work. Because markets are always teaching us lessons, I couldn’t help but add to the original 25 with five new sayings. I’ll follow up in short order with another five.Here are our Sayings 26-30: “Financial market objects at rest tend to stay at rest.” “Realized vol rules the world.” “My portfolio is more diversified and liquid than I thought, said no one ever.” “The ten-year note, not the SPX, is the risk asset.” “Shake hands with the government and sell what they’re selling.” Hope you Enjoy!
