Definition
The S&P 500 Index (Standard & Poor’s 500 Index) is a market-capitalization-weighted index consisting of 500 of the leading publicly traded companies in the United States. It actually features 503 components due to the inclusion of companies that have two different share classes. It’s not merely about size - the selection criteria are rigorous, considering financial viability, liquidity, and sector representation. Despite all that, investors have been known to call it the “500 S&P friends” because who doesn’t love a good mix of overachievers? 🎉
Key Characteristics
- Market Capitalization-Weighted: Companies with larger market caps have more influence on the index’s performance.
- Established: Launched in 1957 by Standard and Poor’s, the S&P 500 has stood the test of time, much like your uncle’s awful dad jokes.
- Float-Weighted Index: Adjusts market capitalizations based on the number of shares available for public trading.
- Benchmark Performance: Although direct investment is impossible, heaps of mutual funds and ETFs track this index like it’s their job (which, spoiler alert, it is)!
