Episode 70: Dr. Wes Gray discusses the unique tax benefits of ETFs and other topics of interest, host Rick Ferri

·56 min·3 clips

A mutual fund sale realizes a $99 capital gain, while an ETF can swap Microsoft for Exxon in kind.

Rick Ferri welcomes Dr. Wes Gray back to the show. Gray is introduced as the CEO of Alpha Architect, a quantitative asset manager, a strategic advisor to ETF Architect, the president of Alpha Architect Global LLC, an author of several books, and a decorated Marine Corps officer. The conversation stays on exchange traded funds and the tax benefits tied to their structure. Gray explains how the topic first caught his attention years earlier. He remembers someone walking him through custom rebalancing and the chance to avoid distributions. Ferri and Gray then slow everything down and use an intentionally oversimplified fund example. They imagine a portfolio that owns Microsoft and later wants Exxon. In a mutual fund, the sale creates a large capital gain that gets passed through to investors. The same realization event shows up in a separately managed account, a hedge fund, a direct brokerage account, or an LP. Gray keeps coming back to the point that taxable realization matters at the account level. Ferri uses the comparison to show why structure changes consequences, not just labels. The discussion then turns to the ETF side of the example. Gray explains that the wrapper can use creation and redemption mechanics to swap out securities more efficiently. He notes that this is where custom baskets matter. The conversation also puts the issue in a broader historical context. Before newer ETF rules, it was not clear who could use custom create redemption, and some firms like Vanguard and iShares had advantages in limited ways. Throughout, Ferri keeps translating the mechanics back into what an investor would actually pay. The tone stays calm and exact rather than promotional. The result is a technical, investor-first explanation of why the ETF structure can reduce capital gains distributions and how that can matter over time.
