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 ...

Amidst these very uncertain times in the economy, geopolitics, and asset prices, it was excellent to welcome Alberto Gallo, founder and CIO of Andromeda Capital Management, back to the Alpha Exchange.

Our conversation first considers the long arc of post-crisis monetary policy. Here, Alberto argues that extended quantitative easing, while stabilizing in the short run, carried structural side effects over time—capital misal...

With early exposure to Paul Tudor Jones and then stints on the sell-side in credit research, Michael Contopoulos is now Deputy CIO of Richard Bernstein Advisors, a macro-oriented asset manager overseeing roughly $20 billion across long-only portfolios. Our discussion centers on portfolio construction in an era of extreme equity concentration and shifting global leadership.

On the equity side, the firm is under-weight the most concen...

It was a pleasure to welcome Louis Gave, the Founding Partner and CEO of Gavekal, back to the Alpha Exchange. Our discussion centers on what he describes as one of the most consequential and underappreciated macro developments today: the mispricing—and now the policy shift—of the Chinese renminbi. Louis is quite bullish on China.

Louis argues that for much of the past decade, China has acted as a powerful deflationary force on the g...

It is busy time, to say the least, for Libby Cantrill, Head of Public Policy at PIMCO. Today’s markets are grappling with vast uncertainties…in US fiscal policy, in Fed independence and leadership, in geopolitics, and in global trade. Libby is charged with helping both the clients and risk-takers of PIMCO better understand the implications of policy that is changing rapidly.

Through her conversations with institutional, retail, and ...

Five years ago, on January 27th, 2021, the frenzied buying and speculation in Gamestop hit its apex. In this short podcast, I look back on one of the more fascinating, and dare I say, dangerous, risk events in modern day markets. The stock was subject to an outright speculative attack. But not the kind most CEOs complain about. This was not Soros taking down the British pound in 1992. This was a retail army of Reddit bandits whose ...

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...

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...

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 ...

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 rathe...

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.

Risk generally falls into 4 categories, monetary (Central Banks), economic (growth and profits), financial (leverage, carry and correlation) and finally, geopolitical. This last category is non-market, market risk.  And in this context, it was a pleasure to welcome Mark Rosenberg, Founder of GeoQuant and adjunct professor at UC Berkeley to the Alpha Exchange for a discussion centered on political risk as a measurable market variabl...

Todd Rapp got his career started in equity options at Goldman Sachs in the late 1990’s, a wild time in which a bubble inflated and burst and provided critical lessons in both gamma and vega risk in the process. Now the CEO of the Fortress Multi-Manager Group, Todd leans heavily on his derivatives DNA in the areas of sourcing uncorrelated return streams, portfolio construction and both measuring and managing risk. Early training has...

It was a pleasure to welcome Jessica Stauth, CIO for Systematic Equities at Fidelity Investments, to the Alpha Exchange. Our discussion explores how quant investing has evolved through cycles of market stress, technological change, and today’s extraordinary concentration in the equity landscape. Reflecting on her start in markets in the aftermath of the 2007 Quant Quake and the onset of the global financial crisis, Jessica highligh...

They say there’s always a bull market somewhere and a chart on doom commentary has surely been up and to the right. Perhaps it’s been the joint decline in the equity and crypto markets. NVDA is down 10% in November and Bitcoin is down almost twice that. Perhaps it’s been that there wasn’t a hard and fast enough of a catalyst to point to…no trade war, Powell presser, CPI surprise or earnings shortfall. These would have at least left...

Welcome back to the Alpha Exchange. In today’s episode, I am joined by Megan Miller, Senior Portfolio Manager and Head of the Options Solutions team at Allspring Global Investments. Her career spans the extremes of market volatility—from learning options trading during the GFC to now overseeing option-based strategies across a $600 billion platform. The conversation centers on how her team uses a GARCH-like modeling framework as pa...

On this episode of the Alpha Exchange, I’m pleased to welcome back Jordi Visser, CEO of Visser Labs and Head of AI Macro Research at 22V. Our conversation centers on one of the most consequential themes in markets today: the intersection of artificial intelligence, exponential innovation, and market structure. With Nvidia’s historic rise as a backdrop and AI’s increasing integration into every sector, Jordi pushes back on the tende...

The global economic and geopolitical order has long been balanced by the United States. Today, however, that traditional stabilizing role is in flux. The drivers of market uncertainty, typically resulting from changes in monetary policy and the economy, are increasingly linked to US politics. Fiscal strain, tariffs, and hyper-partisanship are sources of unpredictability reverberating across markets worldwide. In this context, it wa...

Loyal listeners, I hope your recent days have gone well, even if they are becoming shorter. On my mind – and where I hope to engage your interest for 20 odd minutes – is the topic of risk and uncertainty.
The SPX is at an all time high and it is also highly concentrated with volatile and richly valued but uncorrelated tech behemoths. That’s very unique. Whether you are an AI bull or bear, one thing we must acknowledge is the unique ...
