The Wisdom of Investment–The Folly of Speculation
The Total Stock Market Index Nonetheless, I continue to favor the Wilshire Total U.S. Stock Market Index as the prime benchmark for an index strategy—not to the exclusion of the S&P 500, but as the place to begin for most investors who are not yet indexing. While returns of the two indexes are apt to be identical over the long-run, there seems little to be gained by accepting any short-run deviation from the market. At Vanguard, we began to implement the total market strategy in 1987 with the creation of the industry’s first Extended Market Index Fund, (based on the Wilshire 4500 Index), enabling investors to fill out their S&P 500 portfolios by adding the rest of the market. But, convinced that this two-pronged strategy might someday result in surprisingly high portfolio turnover as stocks moved back and forth between the indexes, in 1992 we introduced the first total stock market index fund, based on the Wilshire 5000 Index. I believe that it is only a matter of time until the total stock market, most easily measured by the Wilshire 5000, becomes the basic standard for the broad-based indexing strategy. The Wisdom of Stock Indexing After more than a quarter of a century of stock indexing, how has it worked? Unbelievably well! Consider the results of Vanguard’s 500 Index Fund since its initial underwriting in 1976. First, it survived, something that can’t be said about 160 of the 356 equity funds in existence when we made our debut.
