This ranking shows the top performing stocks and biggest stock gainers during September 2026, 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.

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.
What this ranking covers
Universe
US-listed companies on NYSE, Nasdaq and NYSE American.
Floors

Measured on
Split-adjusted closes, from the first close inside the month to the last one in it.
Refreshed

Q Does this page recommend the best stocks to buy now?
A

No. This page is an informational ranking of stocks that have already gone up during September 2026. It does not make buy, sell, or hold recommendations and should be used as a research starting point, not financial advice.

Q How can this ranking help explain current stock market trends?
A

The ranking shows where price strength is concentrated during September 2026. Comparing the top gainers by sector, market cap, and recent catalysts can help identify momentum themes and market rotation without implying that any listed stock is a recommendation.

Q Which companies does this ranking include?
A

4,337 companies with a market capitalization above $100 million traded on NYSE, Nasdaq and NYSE American, each with at least one trading day inside September 2026. One close inside the month is enough to qualify, so a company that listed during the month is ranked on the part of it that it traded.

A

The five highest-gaining companies in September 2026 sit in Healthcare, Communication Services, Technology, with the leader INDP in Healthcare. That describes the top of this list, not a sector ranking; the market-context strip above the table reports the median move of each sector's ranked companies.

Q How is monthly stock performance calculated?
A

Monthly stock performance is calculated by comparing the closing price on the last trading day of the month to the closing price on its first trading day, both split-adjusted. A company whose trading history begins inside the month is measured from its first close.

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.
