Quick Access: 52-Week 2025 YTD Dec 2025 Market Cap Dividends

This ranking shows the top performing stocks and biggest stock gainers of December 2025, measured from the last close of November to the last close of December.

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.

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.
