Why Warren Buffett Would Trade Places: Your Small-Cap Cash Advantage

When Warren Buffett took over Berkshire Hathaway in 1964, he transformed a struggling textile company into a financial powerhouse. Over the next six decades, his cash-fueled growth strategy delivered a staggering 5.5 million percent return. Yet here’s the irony that shapes modern investing: if you have less than a few million dollars to deploy, Warren himself has openly envied your position. The advantages you possess as a small investor—flexibility, regulatory freedom, and the raw power of compound growth on manageable cash positions—are precisely what Buffett can no longer leverage at his scale.

The Hidden Edge Small Investors Hold Over Warren

Berkshire’s impressive 19.9% average annual return from 1965 to 2024 masks a striking pattern. The fund’s most explosive years happened decades ago: +77.8% (1968), +80.5% (1971), +129.3% (1976), +102.5% (1979), +93.7% (1985), and +84.6% (1989). These weren’t anomalies—they represented what’s possible when capital remains lean and opportunities remain plentiful.

Buffett himself predicted this slowdown. In a 1994 shareholder letter, he acknowledged that future returns would pale compared to historical performance. More candidly, in a 1999 interview, he stated: “It’s a huge structural advantage not to have a lot of money. I think I could make you 50% a year on $1 million. No, I know I could. I guarantee that.”

Why the frank admission? Because managing smaller cash pools is fundamentally different from deploying $380 billion.

Why Size Matters: Scale’s Impact on Investment Returns

The mechanics are straightforward: the law of large numbers constrains all large-scale investors. Small-cap stocks historically outperform their larger peers precisely because they start from smaller bases. A 10x return on a $100 million investment yields $900 million profit—meaningful, but barely moving the needle for a behemoth like Berkshire. For a retail investor, that same return transforms $5,000 into $50,000, a life-altering gain.

This disparity explains why Buffett, despite legendary skill, now operates at a disadvantage relative to smaller, nimbler competitors and individual investors willing to focus on emerging opportunities.

The Regulatory Barrier Buffett Can’t Ignore

Size introduces another constraint: regulation. Should Berkshire attempt to acquire more than 5% of any publicly traded company, it must file a Schedule 13D disclosure with the SEC. This notification immediately signals Buffett’s move to markets, potentially driving up prices and limiting his strategic flexibility. Individual investors face no such friction.

A retail investor can quietly accumulate stakes in promising small-cap companies without regulatory fanfare or public announcement. Warren cannot. This structural disadvantage—inherent to managing cash of his magnitude—represents perhaps his most underrated competitive handicap.

Building a Small-Cap Strategy with Low-Cost Cash Management

For investors seeking to capitalize on these advantages, the Vanguard Small Cap Index Admiral Shares (VSMAX) offers a compelling vehicle. Designed to track a diversified basket of small U.S. companies, this fund has delivered 9.21% average annual returns since its 2000 inception—a result especially impressive given its ultra-low 0.05% expense ratio (compare this to the 0.97% industry average).

The fund holds 1,324 stocks with a median market cap of $10 billion. Their collective price-to-earnings ratio averages 20.8, representing a near 33% discount to the S&P 500’s current 28.5 P/E. This valuation gap creates genuine opportunity for value-oriented investors managing their cash strategically.

The fund’s structure allows retail investors to harness small-cap outperformance without the friction, scale disadvantages, or regulatory headaches Buffett faces. You get diversification, professional indexing, and the psychological freedom to hold positions without triggering disclosure requirements or market-moving announcements.

The data supporting concentrated small-cap exposure is compelling. When The Motley Fool’s Stock Advisor identified Netflix on December 17, 2004, a $1,000 investment would have grown to $450,256. Their April 15, 2005 recommendation of Nvidia turned the same $1,000 into $1,171,666.

Stock Advisor’s overall track record—942% average return versus 196% for the S&P 500—illustrates what focused research and tactical conviction can achieve when you’re not constrained by Buffett’s regulatory and capital-scale limitations.

The takeaway? Your position as a smaller investor isn’t a disadvantage—it’s a structural advantage that even Warren Buffett has publicly acknowledged he wishes he possessed. The cash available to you, the regulatory freedom you enjoy, and the ability to pivot quickly all represent edges that neither wealth nor decades of investing experience can overcome for large institutional operators.

For investors building a diversified small-cap allocation, the Vanguard Small Cap Index Admiral Shares represents one straightforward path to translating your inherent advantages into sustained wealth creation.
