The S&P 500 is a market-cap-weighted index of 505 large-cap U.S. stocks, representing approximately 80% of the market value of the U.S. stock market. Often synonymous with “the market” in the U.S., the S&P 500 is the closest thing to a default U.S. stock index. Its largest components by weight are mega-cap stocks such as Apple Inc. (AAPL), Microsoft Corp. (MSFT), Amazon.com Inc. (AMZN), class A shares of Facebook Inc. (FB), and class A shares of Alphabet Inc. (GOOGL). The S&P 500 was the benchmark of the first index fund, and the first ETF. An S&P 500 ETF is an inexpensive way for investors to gain diversified exposure to the U.S. stock market, though it has been unusually volatile in the past year amid the coronavirus pandemic and massive disruptions in the global economy.
