Fidelity Total Market Index Fund 

The Fidelity Total Market Index Fund typically allocates a minimum of 80% of its assets to U.S. equities that comprise the Dow Jones U.S. Total Stock Market Index. This particular benchmark is designed to track the overall performance of a wide spectrum of American companies. To achieve returns similar to the index without holding every single security, the fund's management team utilizes a statistical sampling methodology. This involves evaluating specific characteristics such as market capitalization, industry representation, dividend payouts, price-to-earnings (P/E) multiples, price-to-book (P/B) ratios, and expected earnings growth to select a more focused portfolio.
