Why Warren Buffet's ETF Advice and Berkshire's Recent Actions Don't Match—And What It Means for Your Portfolio

There’s an interesting paradox at the heart of modern investing that deserves closer examination. For years, one of the world’s most respected investors—Warren Buffet—has consistently championed a simple, straightforward approach for the average person: invest regularly in an S&P 500 ETF and let compound growth do the heavy lifting. Yet in the final months of 2024, Berkshire Hathaway, the massive conglomerate that Buffet has led since 1965, completely exited its position in the Vanguard S&P 500 ETF (VOO). So which should you follow—the billionaire’s public guidance or his corporate action?

The Strategy Gap Between Individual and Institutional Investors

The short answer is: follow the advice, not the trade. To understand why, it’s essential to recognize the fundamental differences between how Warren Buffet approaches personal investing philosophy versus how Berkshire Hathaway operates as a trillion-dollar enterprise.

When Buffet recommends that everyday investors stick with an S&P 500 ETF, he’s providing guidance based on realistic constraints faced by most people. The average investor lacks the resources, time, and expertise that Berkshire commands. Buffet’s suggestion isn’t aspirational; it’s pragmatic. Meanwhile, Berkshire operates under completely different parameters. The company employs armies of analysts, portfolio managers, and researchers who spend their days evaluating individual businesses, calculating intrinsic values, and making tactical allocation decisions. What works for a trillion-dollar corporation with unlimited research capacity simply doesn’t translate to a retail investor checking their holdings once a quarter.

This distinction matters enormously. Your investment strategy should reflect your unique circumstances—your risk tolerance, time horizon, financial objectives, and available resources. Most people are playing a different game than Berkshire, and that’s perfectly fine. The genius of Warren Buffet’s ETF recommendation isn’t that it’s glamorous; it’s that it actually works for the people who need it.

What Makes an S&P 500 ETF So Compelling for the Long Term

The appeal of investing through a vehicle like VOO comes down to three practical benefits that are difficult to overstate: instant portfolio diversification, access to the world’s most established companies, and remarkably low costs (the expense ratio sits at just 0.03% annually).

On the diversification front, VOO provides exposure to roughly 500 of the largest American corporations spanning every major economic sector. Yes, the mix has shifted in recent years as megacap technology stocks have surged. Companies like Nvidia, Microsoft, Apple, Amazon, Alphabet, Meta, and Tesla—often called the “Magnificent Seven”—now represent around 34% of the ETF’s total value. This concentration reflects real market dynamics, but VOO still maintains genuine sector breadth:

• Information Technology: 34.8%
• Financials: 13.5%
• Consumer Discretionary: 10.5%
• Communication Services: 10.1%
• Healthcare: 8.9%
• Industrials: 8.3%
• Consumer Staples: 4.9%
• Energy: 2.9%
• Utilities: 2.3%
• Real Estate: 1.9%
• Materials: 1.8%

Every company in this index has cleared high bars for market capitalization and financial stability. These are established organizations with proven business models and the resources to weather economic turbulence. Rather than spending countless hours researching and assembling a portfolio of individual stocks, you get exposure to America’s corporate backbone through one straightforward investment.

Positioning Your Portfolio for Decades of American Economic Growth

When you buy an S&P 500 ETF, you’re fundamentally betting on something that Warren Buffet articulated plainly: “For 240 years it’s been a terrible mistake to bet against America, and now is no time to start.” Though he made that observation in the past decade, the underlying logic holds solid. The U.S. economy continues to demonstrate resilience, innovation, and growth potential that few other markets match.

Since its inception, VOO has generated impressive returns that have enriched countless investors. While past performance never guarantees future results, the ETF possesses all the structural advantages necessary to remain a compelling long-term holding. For most people building wealth over 20, 30, or 40 years, an S&P 500 ETF should form a cornerstone position in their portfolio.

Choosing an Investment Approach That Matches Your Situation

The critical takeaway isn’t that Berkshire Hathaway made a mistake selling its VOO position, nor that Warren Buffet’s guidance about S&P 500 ETFs is suddenly misguided. Rather, the lesson is that investment decisions must align with who you actually are, not who you wish to be. The corporation’s decision to shift its portfolio mix reflects its specific needs and market outlook at a particular moment. Your decision should reflect your circumstances.

Unless you have a team of professional investors at your disposal, considerable capital to deploy, and years to dedicate to active stock research, the path that Warren Buffet recommends remains the soundest approach: commit to regular investing in a diversified S&P 500 ETF and maintain that discipline through market cycles. That strategy has proven its worth across decades and will likely continue rewarding patient investors who stick with the plan.
