S&P 500 Weighting Formula

The S&P 500 Index uses a market-capitalisation weighting method. This means companies with larger market capitalisations receive a higher weighting in the index. 

The weight of each company in the index is determined by dividing its market cap by the total market cap of all companies in the index.

Formula: Company Weight in S&P 500 = Company Market Cap / Total Market Cap of S&P 500

This weighting method means that the largest companies, such as Apple, Netflix, and  Microsoft, have the most significant impact on the index's performance.

• U.S.-Only Focus: These are limited to U.S. companies, so it doesn't offer exposure to international markets
