At a Glance
The S&P 500 is the most widely followed equity benchmark in the world, comprising approximately 500 of the largest US companies by market capitalisation. It covers roughly 80% of the total US equity market value and serves as the primary gauge for institutional investors, pension funds, and sovereign wealth funds worldwide. The index uses a float-adjusted, market-cap-weighted methodology, meaning larger companies have a proportionally greater influence on index movements.
