How Does the S&P 500 Work?

The S&P 500 works by providing a weighted average of the prices of 500 large-cap U.S. stocks.

The index uses a market capitalization weighting method, meaning that each stock’s weight in the index is proportional to its market value.

Therefore, larger companies have a greater impact on the index’s value.

The S&P 500 is calculated using a base-weighted aggregate methodology, which takes into account both the share price and the number of shares outstanding.

This means that a $1 change in a lower-priced stock will not affect the index as much as the same change in a higher-priced stock.
