This ranking shows the top performing stocks and biggest stock gainers during September 2020, calculated from the first to the last trading day of the month. It shows which stocks are going up this month, with split-adjusted data used for consistent performance calculations.

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.

Understanding Monthly Stock Performance

Monthly performance rankings reveal short-term momentum patterns and help identify stocks experiencing rapid price movements:

  • Momentum Research: Stocks showing strong monthly performance can help identify where market attention and price strength are concentrated.
  • Sector Rotation: Monthly rankings can reveal which sectors are gaining favor with investors and where market leadership is shifting.
  • Event-Driven Moves: Earnings releases, product launches, and regulatory approvals often create significant monthly price movements.

Using Monthly Data Effectively

  • Combine Timeframes: Compare monthly gainers with 52-week and YTD performance to identify stocks with both short and long-term momentum.
  • Research the Catalyst: Investigate why top monthly performers moved significantly. The reason for the move matters as much as the percentage gain.
  • Watch for Reversals: Extreme monthly gains sometimes precede corrections, so treat the ranking as a research starting point rather than a buy list.
