Quick Access: 52-Week 2026 YTD May 2026 Market Cap Dividends

This ranking shows the top performing stocks and biggest stock gainers of May 2026, measured from the last close of April to the last close of May.

Monthly performance rankings can reveal price strength, sustained momentum, sector rotation, and event-driven moves that are not visible in one-day movers lists. The table is informational only and does not recommend any stock to buy, sell, or hold.

† Return measured from the start of the stock's current trading history (a recent listing or relisting), not from the start of the month.
Gains are computed on split-adjusted closes, so a split inside the month does not read as a move. This ranking is informational and is not investment advice.
