What Is "A Random Walk Down Wall Street"?

"A Random Walk Down Wall Street" is a classic investment book by economist Burton Malkiel, first published in 1973. It introduces the concept of the "random walk hypothesis," which posits that stock market prices are impossible to predict over time because they reflect all available information almost instantaneously. Therefore, future price movements are independent of past movements, making technical and fundamental analysis largely ineffective for consistent outperformance.

• Core Premise: Market prices fully and efficiently reflect all available information, making it difficult for investors to consistently "beat" the market through stock picking or market timing.
• Random Walk Hypothesis: Asserts that successive price changes in individual stocks and indices are independent, akin to a random walk where the next step's direction is unpredictable.
• Efficient Market Hypothesis (EMH): Malkiel extensively discusses the EMH in its various forms (weak, semi-strong, and strong), arguing that even professional fund managers struggle to consistently outperform broad market indexes after accounting for fees.
• Critique of Analysis Styles: The book meticulously dismantles the perceived efficacy of technical analysis (charting past price movements) and fundamental analysis (evaluating a company's intrinsic value) as reliable methods for generating superior returns.
