Standard & Poor’s 500 Index Definition<\/strong><\/h2>\n\n\n\n

The S&P 500, short for Standard and Poor’s 500, is a stock market index that tracks performance of 500 U.S.-based large-cap companies from various sectors.<\/p>\n\n\n\n

It is widely considered a gauge of investor sentiment and its returns reflect the state of the American economy.<\/p>\n\n\n\n

Thus, returns from the S&P 500 typically go up when the economy is doing well and typically trend downwards during a recession.<\/p>\n\n\n\n

The S&P 500 is a market cap-weighted index, meaning companies with the highest valuations have the most impact on the index’s value.<\/p>\n\n\n\n

How to Calculate S&P 500 Index Value<\/strong><\/h2>\n\n\n\n

To calculate the index value, take the price of each share times the number of shares that can be traded on the open market (known as “float” ), to give you a company’s “float-adjusted market cap.”<\/p>\n\n\n\n

Then add the value of all the float-adjusted market caps of the companies in the S&P 500 and divide by the S&P 500’s divisor.<\/p>\n\n\n\n

The divisor is used to account for changes, such as stock splits and new companies entering or exiting the index.<\/p>\n\n\n\n

Also, the sum of market capitalization of companies listed in the S&P 500 amounts to trillions of dollars, so the divisor normalizes the value to a more digestible figure.<\/p>\n\n\n\n
