Research date: September 8, 2026. Performance snapshot: September 1–4 closes. September is not complete; this is not a final monthly ranking.
ChargePoint led the selected source’s early-month ranking, but the measurement window matters as much as the percentage. A list of recent gainers describes what happened; it does not identify the stocks most likely to rise next.
Selected top five from the dated snapshot
StockTitan’s September ranking showed the following through September 4, using split-adjusted closes from the first close inside the month. Its eligible universe contained 4,303 US-listed companies with market capitalization of at least $100 million across NYSE, Nasdaq and NYSE American.
| Rank in source | Company | Ticker | Window gain |
|---|---|---|---|
| 1 | ChargePoint | CHPT | 86.60% |
| 2 | American Outdoor | AOUT | 44.80% |
| 3 | Katapult | KPLT | 44.16% |
| 4 | Cypherpunk Technologies | CYPH | 41.52% |
| 5 | GoPro | GPRO | 38.21% |
This is not the standard August-close month-to-date calculation
The source starts at a close inside September, so it excludes the move from the final August close to September’s first close. Do not compare it directly with a conventional month-to-date series without reconciling that difference. The figures are price changes on the source’s basis, not a dividend-reinvested total-return calculation independently reconstructed by this site.
What to investigate before drawing a conclusion
Check company filings for earnings, financing and corporate actions. Examine trading liquidity and whether a large percentage move followed an unusually depressed starting price. This article does not attribute each move to a specific catalyst because that causation has not been established by the ranking alone.
A large gain is not proof of investment quality
Recent momentum can reverse, and a small-cap security can have substantial spreads and volatility. A price increase does not reveal cash generation, dilution risk or balance-sheet strength. Compare those fundamentals before treating a ranking as a research shortlist.
FAQ: Are these the best-performing stocks for all of September?
No. They are leaders in the stated source and early-month window only. Later sessions can change the order, and other universes or return definitions can produce different rankings.
Use the September coverage hub for broader research rather than treating this snapshot as a buy list.
