Alpha Exchange

It was a pleasure to welcome Alex Urdea, Founder and CIO of Deep Ocean Partners to the Alpha Exchange. Alex traces his career from credit derivatives trading at a large bank to a risk management function at a hedge fund focused on distressed investing to ultimately building an asset-backed private credit platform focused on smaller, less trafficked segments of the lending universe. The conversation centers on how regulatory changes following the Global Financial Crisis, prolonged periods of low interest rates, and shifting investor preferences have reshaped where and how credit risk is priced.
 
Alex describes how traditional public credit markets, including leveraged loans and high yield, have increasingly compressed spreads while loosening covenants, reducing compensation for bearing risk. In contrast, private credit has emerged as an alternative channel for borrowers unable to access bank balance sheets, particularly fast-growing businesses that are asset-rich but cash-flow constrained. He emphasizes that credit underwriting remains fundamentally about downside protection, liquidation value, and recovery — principles shaped by his experience in stress, distress, and complex capital structures.
 
A  theme central to our discussion is the distinction between risk monitoring and risk management. Alex explains how Deep Ocean combines asset-backed lending with data connectivity and real-time monitoring to identify potential issues earlier in the life of a loan, rather than relying solely on periodic reporting or mark-to-market signals. The conversation also explores how macro forces — including rate shocks, tariffs, and supply-chain disruptions — can impose themselves even on carefully underwritten credits, reinforcing the importance of portfolio construction and diversification.

Today’s market landscape is defined by extremes that challenge conventional portfolio construction. A small group of mega-cap stocks now represents an unprecedented share of index weight, profit generation, and capital spending, raising important questions about valuation, diversification, and risk concentration.
 
With this in mind, it was great to have Andrew Lapthorne, Global Head of Quantitative Research at Société Générale, back on the Alpha Exchange. Drawing on long-run valuation distributions and profitability data, Andrew examines whether today’s market qualifies as a valuation bubble, not through narratives, but through measurable historical comparisons. His analysis highlights that while headline index multiples appear defensible due to strong profits among a narrow group of companies, the average stock is more expensive than during prior bubble periods, including the late-1990s technology cycle.
 
Our discussion also examines how passive investing and benchmark constraints have altered market behavior. With capital increasingly flowing through index vehicles, Andrew argues that valuation changes now affect entire indices rather than discrete groups of stocks, limiting opportunities for rotation into “cheap” segments. This dynamic has substantially increased tracking error for active managers and reinforced concentration, even among investors who recognize valuation risk but remain bound to benchmark exposure.

As I share my closing thoughts on 2025, I want to look back with an eye towards pointing out this year’s unique characteristics from a market risk perspective. I start this exercise by highlighting what I consider to be 2025’s three most interesting days from a vol and risk perspective: 1) the April 7th roller-coaster in the VIX  2) the September 10th surge in ORCL and  3) the October 21st melt-down in the GLD. Each of these helps us better understand some of the forces at work in today’s market. Next, I explore two important themes and their implications. First, the “stock up, vol up” dynamic that is increasingly common among stocks, even mega-caps. Here, the market assigns a higher implied volatility when pricing options on stocks that have often surged in value. It speaks to FOMO and a winner-take-all notion in which stocks are often treated as options. Second, I discuss the incredibly low level of both realized and implied correlation among stocks in the SPX. I consider this a risk hiding in plain sight and something that may be leading investors to underestimate the true level of risk they are taking.

I thank you for being a listener this year and wish you a fantastic 2026.

It was a pleasure to welcome Ian Harnett, co-founder and Chief Investment Strategist at Absolute Strategy Research, to the Alpha Exchange. Our discussion explores how long periods of low volatility and abundant liquidity can quietly allow systemic risks to accumulate outside the traditional banking system.
 
Drawing on lessons from the Global Financial Crisis, Ian explains why today’s financial system—now dominated by non-banks rather than banks—requires a different risk framework.  While post-GFC regulation focused on large banks and insurers, much of the system’s leverage and liquidity transformation has migrated toward pension funds, private equity, insurance companies, and private credit vehicles. In the U.S. alone, roughly three-quarters of private-sector financial assets are now controlled by non-banks, reshaping how shocks can propagate through markets. A key theme of the discussion is that systemic risk is multiplicative rather than additive.
 
Ian argues that past crises were often triggered not by the largest institutions, but by smaller nodes in the system that proved critical once stress emerged. Today, he highlights the growing role of private-equity-backed insurers, which tend to hold riskier assets, maintain lower capital buffers, and allocate more heavily to private credit—an area that remains largely illiquid and difficult to mark to market. Ian’s work emphasizes cash flow as a central lens for assessing vulnerability.

Kumaran Vijayakumar has spent his career in the equity derivatives market, first as an exotics trader and later in running large risk-taking desks in listed and OTC options. Now, the CEO of DataDock Solutions, a firm he Co-Founded in 2018, Kumaran and his team are developing analytical tools that allow sell-side flow desks to better understand the risks they take and clients they take it for. Our discussion explores the challenges inherent in evaluating client flow, and how data-centric infrastructure has changed the way risk is assessed.
 
With the premise that “what you can measure you can manage and improve”, we discuss DataDock’s efforts to build tools capable of ingesting large-scale trade history and simulating outcomes at the most granular level. In equity derivatives, where trades move quickly and visibility is often instantaneous, desks have historically made decisions based on memory and anecdotal assessments of “good” versus “bad” flow. Kumaran describes this as a space where information is abundant, but structured insight often lags execution speed.
 
Our discussion highlights a key theme: not all flow that loses money is detrimental, and not all flow that is profitable is necessarily strategic. Instead, Kumaran notes that client value emerges when one analyzes trade behavior across time, including delta hedge quality, volume risk transfer, roll probability, expected event-driven distribution, and the role of flow as portfolio offset rather than standalone P&L.
