What Is the Wilshire 5,000 Stock Market Index?
The Wilshire 5,000 Total Market Index is a stock market index that tracks the performance of (nearly) the entirety of the publicly traded U.S. equity market. Like other stock indexes, it is a collection of stocks whose aggregate performance can be used as a sort of barometer for the market. It comprises thousands of American stocks and is considered by many investors and analysts to be the most accurate gauge of the U.S. stock market at large.
The Wilshire 5,000 is so named because, at its inception in 1974, it included around 5,000 stocks. By the end of the 20th century, it grew to include over 7,500 before shrinking back to under 5,000 once again. As of December 31st, 2021, the index included 3,687 stocks.
Because it includes more stocks than other popular bellwether indexes like the S&P 500, the Wilshire 5,000 is one of the most popular benchmarks against which to compare the returns of particular funds or individual portfolios. The index’s ticker symbol is FTW5000.
How Is the Wilshire 5,000 Weighted?
There are actually several versions of the Wilshire 5,000, each with its own weighting protocol. Most commonly, when investors and analysts discuss the index or mention its value, they are referring to the full-cap version, which weighs component companies according to their unadjusted market capitalizations.
- Full Capitalization: The full-cap version of the index weighs component companies by their total market cap (i.e., the total market value of all of their outstanding shares of stock).
- Float-Adjusted Capitalization: The float-adjusted version of the index weighs companies by their float-adjusted market cap, which takes into account the total value of all shares of stock that are available for public trading. This method excludes shares that are “locked away” because they are held by company insiders or governments.
- Equal Weight: This version of the index gives every component company equal weight in the index’s calculation regardless of company size.

What Is the Buffet Indicator (Wilshire-to-GDP Ratio)?
In 2001, famed value investor Warren Buffet stated that the ratio of the market capitalization of all of a country’s stocks to that same country’s GDP (gross domestic product) “is probably the best single measure of where valuations stand at any given moment.”
In other words, comparing the total market value of all publicly traded U.S. stocks to the GDP is a good way to tell if the American equity market is undervalued or overvalued at any given time. As of March 1st, 2022, the Buffet Indicator stood at about 185%, theoretically indicating that American stocks are broadly overvalued.
