New in 2026
No new-in-2026 S&P 500 additions with price history yet. The 2026 S&P 500 additions (FDXF and HONA, both 2026 spin-offs) have no December 31, 2025 price, so they cannot be measured on a genuine year-to-date basis — and are excluded rather than ranked on invented data. When a 2026 addition with a full price history appears, it will be listed here.
September 2026 return measured from the last close before the 1st to the last close of the month across S&P 500 constituents with usable monthly price data. Stocks without a genuine pre-month price (e.g. 2026 spin-offs) are excluded; prices adjusted for splits and dividends. Source: Yahoo Finance.
