The Standard and Poor’s 500, or S&P 500, is a stock index that tracks the performance of 500 leading companies listed on U.S. stock exchanges.

In 2025, the S&P 500 index rose to a record $6715,79, adding 14,43% year-to-date. Bitcoin Over the same period, it has grown by 32%, rising above $125,000 last Saturday, October 6.
