How often are the S&P indices updated?

The S&P indices are updated frequently to reflect market changes and ensure that they accurately represent the underlying asset classes. In general, major S&P indices, such as the S&P 500, are updated in real-time during trading hours, which means they reflect ongoing price changes for the constituent stocks throughout the day. The index values change dynamically as trades are executed on the stock exchanges. In addition to real-time updates, periodic rebalancing occurs, usually on a quarterly basis, to adjust the indices based on market capitalization changes, company performance, and other criteria. This ensures that the indices remain representative of the market as a whole.
