The top US-listed stocks of September 2020 by monthly gain, on split-adjusted closes. Ranks 3,337 companies above $100M on NYSE, Nasdaq and NYSE American.
Looking for intraday moves instead? Today's stock movers ranks the current session's alert board, so it measures against whichever session is running rather than covering a fixed window.
Over September 2020, 27% of the 3,337 ranked companies finished higher and the median move was -4.2%; Healthcare led on median (-1.5%) and Energy lagged (-13.9%).
The S&P 500 fund (SPY) moved -5.02% between its Sep 1, 2020 and Sep 30, 2020 closes.
Each ranked company's gain runs from its own first close inside the period, so a company listed later in the period is measured over a shorter window.

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.
