Why Small-Cap ETFs Beat Mutual Funds

Passive investing wins on cost almost everywhere — except one corner of the market where active managers keep earning their fees: small caps. This episode breaks down why the small-cap segment is structurally different, and why the vehicle you choose to access it matters more than in almost any other asset class.

We start with the "why": small-cap stocks average just 6 analysts of coverage versus 30 for large caps, leaving far more mispriced companies for a skilled manager to find. That thinner coverage, combined with a wider spread between the best and worst performers, has historically let active small-cap managers post real alpha — nearly 60% cumulative outperformance over the last 30 years, and a one-year success rate above 50% in the 12 months through June 2026. We dig into small-cap value specifically as a "sweet spot" that stacks the size premium and value premium together, why it offers a natural hedge against mega-cap tech concentration, and the real risks that come with it — higher volatility, long cyclical stretches of underperformance, and wider tracking error for anyone using an index fund. We also cover why ETFs generally beat mutual funds on cost efficiency across the board, avoiding cash drag and the tax inefficiency of capital gains distributions, and we close with a look at where the Trail Boss Bot's ARDL model currently stands — including why its "PeeWee League" is actually full of mega-caps like KO and WMT, not true small-caps, and the case for building a real Small-Cap League into the roster.

Bottom line: if you're going passive almost everywhere else, small-cap value might be the one place where paying for skilled active management — or at least factor-tilted exposure — still pays for itself.

Extra questions to explore:

• If a dedicated Small-Cap League gets added to the ARDL model, would tickers like IJR or AVSG likely show higher or lower persistence than the current PeeWee League names?
• Given small-cap value underperformed the S&P 500 in 8 of the last 10 years, how would you build conviction to hold through a cycle like that?
• How would a small-cap value ETF fit into the Baseball Portfolio System — Peewee, Minor League, or its own new tier entirely?
• Does the ARDL model's "noise vs. trend" framework get more or less useful when applied to a more volatile, less-covered stock universe?
