Study Reveals Only a Quarter of Stocks Outperform Market; 60% Fail Shareholders Over 100 Years

A new study by Hendrik Bessembinder from Arizona State University's W.P. Carey School of Business has revealed stark realities about stock market performance over the past century. The research, which analyzed nearly 30,000 publicly traded U.S. stocks between 1926 and 2025, found that only 27.6% managed to outperform broader market indexes, while a staggering 60% of these companies actually diminished shareholder wealth.

The study highlights the uneven distribution of returns within the stock market, with broad indices generating impressive long-term gains that mask significant underperformance by individual stocks. Over the examined period, the overall stock market delivered an annualized return of approximately 10.1%, transforming every initial investment dollar into more than $15,000. However, this aggregate success is overshadowed by the fact that fewer than half of all individual stocks produced positive lifetime returns.

The median performance of a typical stock was even more disappointing: it delivered a lifetime return of -6.9%. This means that the majority of companies failed to outperform not only the market but also low-risk investments like Treasury bills, with less than 41% of stocks surpassing these benchmarks during their public trading lifetimes.

The research underscores how wealth creation in the stock market is highly concentrated among a select few firms. For instance, while over $91 trillion in shareholder wealth was generated from U.S. equities between 1926 and 2025, only 46 companies were responsible for half of this total value addition. This concentration has intensified since Bessembinder's earlier study covering the period up to 2016, which identified 89 firms as key contributors.

Leading the list of top wealth creators are well-known tech giants such as Apple and Nvidia, with Apple alone accounting for over $5 trillion in shareholder wealth creation. Together, five companies—Apple, Nvidia, Microsoft, Alphabet (Google), and Amazon—contribute more than one-fifth to the total net wealth generated by U.S. stocks since 1926.

The study also reveals that just 1,082 out of over 29,754 firms were responsible for all market-wide net wealth creation during this period. In contrast, nearly six in ten companies detracted from shareholder value compared to investing in one-month Treasury bills, highlighting the significant risk involved in individual stock selection.

These findings challenge conventional wisdom about successful investments, emphasizing that substantial gains often stem from consistent, long-term compounding rather than short-term high returns. The research serves as a reminder of the inherent risks and challenges for investors seeking above-market returns through individual stock picking.
