What is S&P 500 Companies By Weight?

S&P 500 Companies By Weight is a free tool that tracks all the companies in the S&P 500 and the percent of each company in the S&P 500. For example, the S&P 500 holds 500 companies, but each company is not held in equal amounts. Our tool tracks every company and updates daily its weight in the S&P 500.

Are the S&P 500 companies’ weights live?

Yes, the weight for each company is live and updated daily at the end of trading hours. This ensures that users are able to get the latest weights of each company in the S&P 500.
