Podcast Summary: Masters in Business – At The Money: Finding Alpha via Unique ETF Strategies

Host: Barry Ritholtz, Bloomberg
Guest: Wes Gray, Alpha Architect
Date: March 11, 2026

Episode Overview

This episode of "At The Money" dives deeply into the evolving world of finding alpha—i.e., excess return—through innovative, boutique ETF (Exchange Traded Fund) strategies. Barry Ritholtz engages Wes Gray, a quantitative investing expert from Alpha Architect, in a candid conversation about how everyday investors—and not just hedge fund elites—might pursue better-than-market returns with transparent, rules-based, sometimes unconventional ETFs focused on value, momentum, and risk management.

Key Discussion Points & Insights

What is Alpha in the ETF Context?

• Defining Alpha:
  • Wes Gray underscores that for "the rest of us," alpha means "delivering unique, differentiated strategies after fee and after taxes that help you shape... your portfolio beyond the core of what you already have" (03:07).
  • Classic, hedge fund-level alpha as generated by legends like Jim Simons is out of reach for public investors—ETF "alpha" is about smartly diversifying away from traditional cap-weighted indexes.

Factor Exposure: The Heart of ETF Alpha

• Factor-based Approaches:
  • “Pretty much all of it is [factor exposure]...The alpha idea is like we want to deliver you these unique market factors, but we want to make sure you capture all those efficiently, low cost and with good taxes.” – Wes Gray (05:49)
  • Factors include value, momentum, quality, etc.; ETFs can systematically provide access to these.

Why Don’t Factors Get Arbitraged Away?

• Investor Behavior & Limitation:
  • "Humans are going to human...you got to have discipline, you got to have long time horizon, you got to stick to the plan...We all know what you’re supposed to do, but that doesn’t mean everybody does it." – Wes Gray (06:50)
  • Well-known factors (like value) can underperform for long stretches—most investors don’t have the discipline to stick through tough times, preventing easy arbitrage.

The Pain of Underperformance

• Memorable Moment:
  • Barry Ritholtz references Gray’s classic paper: “‘Even God would get fired as an active value investor or fund manager.’ How is that possible?” (08:23)
  • Wes Gray: Markets can make even perfect strategies look bad for years: "They generally work in a way that they’re going to push you to maximal pain before the gains are there. And that’s just the nature of how markets clear and how they work." (08:50)

The Pitfalls of Quant Backtesting

• Backtest Overfitting:
  • Barry questions the reliability of backtests (09:33-10:27).
  • Gray advises: “Never trust any past performance...What you should understand is what is the process fundamentally and then obviously why has this work and why will it continue to work?” (10:27)
  • Good strategies must carry the tradeoff: “It’s not...an easy thing to deal with in the future.” (10:27)

Incentives, Research, and Biases

• Academic vs. Industry Research:
  • Gray heavily discounts backtests from product sponsors: "It’s like kind of like there’s a, there’s a study on how to this drug from like sponsored by Pfizer Research. Like I just can’t believe it at the outset." (12:32)
  • Academic research is not perfect but less biased than asset manager promotions.

Unique & Notable ETF Strategies by Alpha Architect

(Products discussed; investor fit and structural differences highlighted)

Core Factor Models: QVAL, IVAL, QMOM, IMOM

• What Are They?
  • QVAL/IVAL: Value-focused (US/international)
  • QMOM/IMOM: Momentum-focused (US/international)
• Approach:
  • Built using “academic factor looking things”—pure implementations that do not track the S&P 500 but rather own high-scoring stocks within their factor universe and rebalance frequently.
• Who Buys Them?
  • Investors with long time horizons and strong understanding of factor investing. “It really does require kind of this 10 year horizon and a lot of understanding of the process and why it works.” – Wes Gray (15:25)
• Notable Comment:
  • "We are not closet indexers...But we don't like to sell our products because it's really important that people buy our products to understand what they're getting into." – Wes Gray (15:25)

The Box Spread ETFs: BOXX & BOXXA

• BOXX (1-3 Month Box ETF) and BOXXA (Intermediate Duration)
  • Leverage an options market strategy ("box spreads") to capture the implied risk-free rate, similar to but sometimes more attractive than Treasury yields.
  • "How do we deliver excess returns net of fees and taxes and all that good stuff over the equivalent duration? ...we have done this..." – Wes Gray (16:29)

Tail Risk ETF: CHAOS

• Design & Purpose:
  • Provides protection against market crashes via options, but not a free lunch; aims to avoid the typical “bleed to zero” of tail-risk strategies by selling put spreads to offset costs.
  • “If Trump says something crazy or North Korea nukes us tomorrow and the Vix goes to 100 and the market’s down by 50, chaos will probably be doing pretty good.” (19:40)
  • During Q1 2020, CHAOS “exploded upwards like 25, 30%” (19:29 Barry), confirming its crisis hedge premise.

Inflation/Deflation Hedge ETF: HIDE

• Approach:
  • "Poor man’s managed futures" at low fee (29bp); combines bonds (deflation protection), commodities (inflation protection), and real estate. Uses trend-following; defaults to cash if nothing’s trending.
  • “Hyperinflation or deflation protection in one product so you don’t have to think too hard.” – Wes Gray (20:28)

Notable Quotes & Memorable Moments

• On the Realities of Public ETF Alpha:
  • “It’s the poor man’s alpha. It’s not the 2 and 20 alpha, but that’s just the reality of, you know, being in a product with a lot of scale and serving the public.” – Wes Gray (04:40)
• On Investor Psychology:
  • “Humans are going to human...It’s kind of like dieting and like being in shape. Like we all know how to get ripped...But that doesn’t mean everybody does it.” – Wes Gray (06:50)
• On Backtests:
  • “Don’t believe any back test, especially if it shows a great thing unless it also shows why it’s so bad.” – Wes Gray (10:27)

Takeaways for Listeners

• The pursuit of alpha in public markets is about systematic, disciplined exposure to market inefficiencies (factors), not out-of-this-world returns.
• ETF “alpha” often means embracing unique, sometimes uncomfortable investment exposures—value, momentum, alternative asset classes, and risk overlays.
• Alpha Architect’s approach is unapologetically “pure,” giving investors access to true factor tilts—not watered down or closet-indexed strategies—but requires commitment and a strong stomach for tracking error.
• Boutique "satellite" ETF strategies can provide diversification and “portfolio insurance” when paired with core passive equity market exposures.
• Don’t fall for marketing backtests—always ask what the risk is, not just the return.
