What Is the S&P 500?
The Standard & Poor’s 500 Index (S&P 500) is a market capitalization-weighted index. This means that companies with larger market values have a greater influence on the index’s movement. It includes companies from various sectors, including technology, healthcare, finance, and consumer goods.
The S&P 500 Dividend Aristocrats are the components that have raised their dividends for 25 consecutive years.
It is one of the most widely followed equity indices, comprising about 80% of the total market capitalization of U.S. public companies, with an aggregate market cap of over $43 trillion as of January 2024.
As of September 30, 2024, the nine largest companies on the list of S&P 500 companies accounted for 34.6% of the index’s market capitalization and were, in order of highest to lowest weighting: Apple, Microsoft, Nvidia, Amazon.com, Meta Platforms, Alphabet (including both class A & C shares), Berkshire Hathaway, Broadcom, and Tesla.
You can’t invest directly in the S&P 500 because it’s an index but you can invest in one of the many funds that use it as a benchmark and track its composition and performance.
