The S&P 500 has delivered an 11 percent annual return since 1958, but the companies producing that return have turned over almost completely. In 1996 the index’s ten largest holdings were Coca-Cola at $130.6 billion, ExxonMobil at $121.7 billion, Intel at $107.6 billion, Microsoft at $99.4 billion, General Electric at $97.4 billion, Merck at $86.4 billion, International Business Machines at $73.5 billion, Procter and Gamble at $72.5 billion, Johnson and Johnson at $66.3 billion and Walmart at $52.2 billion. Three decades later only Microsoft remains in the top ten, and the current leaders, Apple, Nvidia, Amazon, Meta Platforms, Alphabet and Tesla, were either in crisis, private or nonexistent in 1996.
The index does the picking for you
That turnover is the argument for the Vanguard Total Stock Market ETF. VTI holds the entire U.S. equity universe, so it does not need to identify the next generation of winners. As a company’s market capitalization grows, the fund’s weight in that name grows with it. The mechanism is automatic: no analyst committee, no rebalancing judgment, no forecast required.
Small caps enter the pipeline earlier
The S&P 500 limits itself to large, established companies. VTI adds small-cap and mid-cap names that often become the next decade’s leaders before they graduate to the large-cap index. An investor who bought the 1996 top ten and held would have done respectably, but would have missed every emerging tech giant that reshaped the economy and the index after 1996.
Cost and diversification stay constant
VTI’s expense ratio remains near zero and its breadth, thousands of issuers, dilutes single-stock risk without sacrificing exposure to the outliers that drive long-term returns. The fund’s structure means the portfolio that matters in 2056 will look nothing like the portfolio today, and the investor does not have to decide which names survive.
What to watch
The only variable is whether the U.S. equity market continues to compound at something like its post-1958 pace. If it does, VTI captures the upside by construction. If it does not, no stock-picking strategy has a reliable record of outperforming a broad, low-cost index over thirty years.
