How S&P 500 Works

The S&P 500 is a market capitalization-weighted index, meaning that companies with larger market capitalizations have a greater impact on the index's performance.

Index Calculation Methodology

The S&P 500 is calculated using the following formula:

The divisor is a proprietary figure that is adjusted for stock splits, dividends, and other corporate actions to ensure that the index accurately reflects the market.
