In 1999, at a Berkshire Hathaway annual meeting, Warren Buffett said something we’ve never forgotten:
“If I was running $1 million today, or $10 million for that matter, I’d be fully invested. It’s a huge structural advantage not to have a lot of money. The universe I can’t play in has become more attractive than the universe I can play in. I have to look for elephants. It may be that the elephants are not as attractive as the mosquitoes. But that is the universe I must live in.”
The same year, he claimed he could guarantee 50% annual returns on $1 million by accessing exactly those kinds of opportunities — opportunities he had personally exploited in the 1950s, before capital constraints at Berkshire forced him up-market into mega-cap territory.
Two things in that quote are striking. First, the world’s most respected investor was saying — publicly, on the record — that being small was an advantage, not a limitation. Second, he was implying that the inefficiencies he made his early career on still existed, just in places he could no longer reach.
Twenty-five years later, both points are still true. And they shape how we build client portfolios at Wilco.
What Buffett was talking about
The universe of publicly traded equities sorts roughly into three buckets by market capitalization:
- Large-cap (~$10B+) — household names. Apple, Microsoft, JPMorgan, Walmart. Followed by hundreds of analysts, owned by every large fund, priced efficiently by deep institutional participation.
- Mid-cap (~$2B–$10B) — established but less covered.
- Small-cap (~$300M–$2B) and below — a much wider universe of companies with thin analyst coverage, light institutional ownership, and frequent mispricing. This is where Buffett’s “mosquitoes” live.
A fund manager with $50 billion under management cannot meaningfully buy a $500 million small-cap company. Even taking a 5% stake would be only 0.05% of their fund — not worth the diligence work. And if they did, the stake would often exceed the company’s average daily trading volume, making it nearly impossible to exit without moving the price against themselves.
So they don’t. The world’s largest managers — by necessity, not by preference — concentrate their effort in the large-cap universe where they can deploy capital efficiently. The small-cap universe is left to a much smaller pool of participants.
Why this creates real opportunity
A few structural facts compound on each other:
1. Coverage gap. Large-cap stocks are followed by dozens of professional analysts each. Many small-caps are followed by zero or one. Less coverage means more information that hasn’t yet been reflected in the price.
2. Forced flows. When a stock crosses size thresholds — entering or leaving an index, hitting a fund’s market-cap floor, getting added to a mid-cap mandate — institutional buying and selling can move the price for reasons that have nothing to do with the underlying business. A patient small-cap investor can be on the right side of those flows.
3. Less algorithmic competition. High-frequency trading firms care about liquidity. The deeper and faster the order book, the more profitable their strategies. They concentrate in large-caps and ETF arbitrage. Small-caps are quieter and more fundamentally driven.
4. Founder-led companies. Many small-caps are still run by their founders or operating CEOs, with meaningful inside ownership. Capital allocation tends to be more thoughtful when the CEO’s net worth is in the stock. Long-window aggregate studies have shown founder-led companies modestly outperform peer non-founder-led companies.
5. The size premium. There’s a long-documented historical pattern of small-caps earning higher returns than large-caps over long horizons, partly as compensation for lower liquidity and higher volatility. The magnitude has varied considerably over time. The direction has been consistent across decades and countries.
None of this is a free lunch. Small-caps are more volatile, more sensitive to recessions, and more likely to fail outright. The structural opportunity comes with structural risk. But for the type of investor willing to bear that risk and patient enough to ride out the volatility, the long-run history has rewarded the willingness.
Why we can fish here when most can’t
Wilco Financial isn’t $50 billion. We’re a boutique investment adviser, and that places us squarely in the category Buffett was describing — small enough to take meaningful positions in companies the giants can’t touch, while having the analytical experience to underwrite them.
Our portfolios deliberately overweight small-cap stocks relative to a market-cap-weighted benchmark because:
- We have access to the universe Buffett said he wished he could still reach.
- We’re not constrained by mandate floors that force us up-market.
- We can hold positions long enough for the underlying business value to be recognized — often years.
- We’re not subject to redemption pressures that force open-end mutual funds to sell on the worst days.
The work isn’t trivial. Small-cap investing rewards careful business analysis, patience, and a willingness to hold positions through volatility that would force a forced seller to capitulate. That’s where two decades of institutional investment experience — analyzing businesses at deep-value and distressed hedge funds across multiple market cycles — earns its keep.
What this means for our clients
For clients with appropriate risk tolerance and a long enough horizon, the practical results of our small-cap tilt should be:
- Higher expected returns over long periods — driven by the structural premium plus security selection
- Higher short-term volatility — small-caps move more aggressively than large-caps in both directions
- Periods of underperformance vs. the S&P 500 — particularly when mega-caps dominate (as in much of the 2018–2023 cycle, when a handful of large-cap names drove most of the index’s return)
- A portfolio that looks different from a vanilla index fund — because the math behind the tilt is different from the math behind market-cap weighting
We’re transparent about this during onboarding. Not every client wants a portfolio that looks different from the S&P 500 in any given year, and that’s a legitimate preference. For clients who do — and who can stay disciplined through the bumpier ride — the structural case is durable, and we lean into it.
The honest caveats
A few things we don’t claim:
- We can’t promise outperformance. Nobody can. Buffett’s “guaranteed 50%” was a rhetorical flourish, not a regulatory representation, and even he no longer operates in that universe.
- Past relative performance of small-caps does not guarantee future relative performance. The size premium has had long stretches of underperformance — notably 2014–2023 in the U.S., when large-caps decisively beat small-caps.
- Volatility is real, and behavioral discipline matters. A small-cap tilt only works if you don’t sell during the drawdowns it inevitably produces.
- Position sizing and risk management matter as much as security selection. Owning a small piece of a great company doesn’t move a portfolio. Owning the wrong size of a deeply mispriced one can — in either direction.
What we believe is durable:
The structural reasons large funds can’t meaningfully operate in the small-cap universe haven’t changed since Buffett described them in 1999. If anything, AUM concentration in the world’s largest managers has grown — which means the relative opportunity for smaller, focused investors in the small-cap space has likely grown along with it. The arithmetic of “you cannot meaningfully invest in a $400 million company from a $50 billion fund” is the same arithmetic it was 25 years ago, and the same arithmetic it will be 25 years from now.
We cannot promise the size premium will reassert itself in any particular year. We can promise we are doing the work — and that the universe we are working in is structurally different from the one the largest firms have to confine themselves to.
