Explaining Berkshire's approach to owning businesses rather than trading stocks.

This one-liner encapsulates Berkshire's entire investment philosophy. Buffett doesn't buy stocks; he buys businesses. And when you buy a business, you don't flip it next quarter — you own it. This approach eliminates transaction costs, minimizes taxes (by deferring capital gains), and allows compounding to work its magic. Berkshire's core holdings in Coca-Cola (since 1988), American Express (since 1991), and GEICO (wholly owned) demonstrate this philosophy in action. The "forever" mindset also forces extraordinary selectivity: if you're going to live with a decision indefinitely, you'll make it very carefully.

In an investment world dominated by quarterly earnings reactions and ETF flows, the "forever" philosophy is increasingly rare. Yet study after study shows that the biggest gains in stock market history come from a small number of decisions held for very long periods. The tax advantages alone of long-term holding can add hundreds of basis points to annual returns.

Before buying any stock, ask: "Would I be comfortable owning this business for 10 years if the stock market closed tomorrow?" If the answer is no, don't buy. After purchasing, stop checking the price daily. Focus on the underlying business performance: revenue growth, margins, competitive position. Remember that selling triggers taxes and transaction costs that permanently reduce your capital base.
