Besides acquiring top stocks, FXAIX is also into security lending to generate income for investors. Due to its highly diversified structure, FXAIX is less prone to industry-wide market volatility. With so many stocks, numbering more than 500 and spread across different holdings, investors’ funds spread among many industries and stocks.

The strategy deployed by the managers of FXAIX is simple. They use sampling techniques to select the stock to include in the portfolio. Stocks are chosen based on their current projected value, dividend yields over a time period, and many other factors. 

It is also important to note that the stocks in the S&P 500 are the ones with the highest market cap in the US stock market. As an investor, this fund grants you access to the US stock market, where highly profitable stocks are bought and sold.

FXAIX invests about 80% of its assets in these stocks. When you skim through its stock holdings, as you will see in the table below, you will find many highly profitable companies spread across different industries like finance, IT, energy, and more.
