The S&P 500 is comprised of the 500 biggest corporations on any exchange in the United States. These include household names like Google's Alphabet, Apple, Facebook, Microsoft, Amazon and Tesla.
The S&P 500 stocks are not chosen automatically, but are instead chosen by an index committee within the S&P 500. The committee sometimes elects new stocks or nixes other ones. This can happen once every few years or even several times in a year or two – although the latter is very uncommon.
