Source: S&P Dow Jones Indices, Market Attributes: U.S. Equities, December 2025. S&P publishes cumulative counts: 304 up, 215 up at least 10%, 116 up at least 25%, 196 down, 124 down at least 10%, 41 down at least 25%. The bucket figures here are those cumulative counts subtracted from each other, which is arithmetic on published numbers rather than a separate estimate. They sum to 500.

An index return is an average of the companies inside it. The S&P 500 rose 16.39% in 2025 while its best constituent gained 563% and its worst lost 67%. That spread, not the index number, is what stock picking has to play for.
