What is the S&P 500?

The Standard & Poor’s 500 Index (S&P 500) is one of the most widely followed stock market indices in the world.

The formula used is: Index Value=∑Market Capitalization of All 500 CompaniesIndex Divisor\text{Index Value} = \frac{\sum \text{Market Capitalization of All 500 Companies}}{\text{Index Divisor}}

The index divisor is adjusted periodically to account for stock splits, dividends, and corporate actions, ensuring consistency in the index value.
