Why Does Warren Buffett Consider Market Prediction a "Fool's Game"?

As a leading figure in value investing, Warren Buffett has repeatedly emphasized in his shareholder letters that attempting to predict short-term market fluctuations is a futile and foolish endeavor. He calls this practice a "fool's game," primarily for the following reasons:

1. Short-Term Market Unpredictability

• Buffett believes short-term market performance is influenced by unpredictable factors such as investor sentiment, economic events, and geopolitics, making accurate forecasts nearly impossible.
• He cites his mentor Benjamin Graham’s famous adage: "In the short run, the market is a voting machine, but in the long run, it is a weighing machine." Short-term markets resemble emotion-driven voting rather than rational assessment, leading to frequent prediction failures.

2. Focus on Long-Term Value Over Short-Term Speculation

• Buffett’s investment philosophy centers on value investing—selecting stocks by analyzing a company’s intrinsic value (e.g., profitability, competitive advantages, management quality)—rather than guessing market movements.
• He argues that market prediction is inherently speculative, akin to gambling. True investing should ignore short-term noise and focus on long-term business performance. For instance, in his 1987 shareholder letter, he stated: "We don’t attempt to predict the markets; we attempt only to purchase undervalued businesses."

3. Historical Evidence and Data

• Buffett observes that many professionals (e.g., fund managers, economists) attempt market predictions but achieve low success rates. Berkshire Hathaway’s long-term success stems from ignoring market forecasts and holding quality assets (e.g., Coca-Cola, Apple).
• In multiple shareholder letters, he mocks "market prognosticators," noting their predictions often prove incorrect, wasting time and effort.

4. Risk and Opportunity Cost

• Market prediction may lead to frequent trading, increasing transaction costs and tax burdens while missing opportunities for long-term compound growth.
• Buffett advises investors to hold stocks like business owners, patiently waiting for value realization, rather than playing the "prediction game."

In summary, Buffett views market prediction as a "fool's game" because it contradicts rational investment principles. He encourages wealth creation through thorough research and long-term holding—a core tenet of value investing that has withstood the test of time.
