Warren Buffett recently shared a fascinating insight into one of the most successful investments in history: Berkshire Hathaway's stake in Apple.
He revealed that Berkshire has realized gains of over $100 billion from Apple, yet he also candidly admitted to a timing misstep, stating he "started selling too soon." This comment perfectly captures the complex balancing act that even the world's most famous investor faces. On one hand, he continues to see Apple as an exceptional business. On the other hand, practical risk management prompted him to trim the position.
So, why did Berkshire sell shares of a company Buffett still admires? There were three primary reasons. First was portfolio concentration. The Apple investment had grown so large that it represented an outsized portion of Berkshire's portfolio. Prudent risk management suggests not having too many eggs in one basket, no matter how strong the basket seems. Second, Buffett was mindful of potential tax changes. He decided to lock in enormous gains at the current 21% corporate tax rate, anticipating that this rate could rise in the future. Third, a persistent regulatory overhang, including antitrust lawsuits from the U.S. Department of Justice and scrutiny from the European Union, added a layer of uncertainty that made taking some profits a sensible move.
However, Apple's incredible performance is what makes this a story of timing. The launch of the iPhone 17 in late 2025 fueled a record-breaking first quarter for 2026, with revenues soaring. This product cycle success, combined with Apple's massive $110 billion stock buyback program announced in 2024, relentlessly pushed its share price higher. This powerful value creation made Berkshire's sales in 2024 and 2025, which seemed wise at the time, appear premature in hindsight. Buffett's reflection isn't a change of heart about Apple's quality, but an acknowledgment that timing the market is difficult, even when you're managing risks perfectly.
- Portfolio Concentration: The risk associated with having a large portion of an investment portfolio allocated to a single asset or a small number of assets. If that asset performs poorly, it can have a disproportionately negative impact on the entire portfolio.
- P/E Ratio (Price-to-Earnings Ratio): A valuation metric that compares a company's current share price to its per-share earnings. A high P/E can indicate that investors expect higher future growth, or that a stock is overvalued.
- Stock Buyback: A process where a company repurchases its own shares from the marketplace. This reduces the number of outstanding shares, which tends to increase earnings per share (EPS) and the stock's market value.
