Neuroone Medical Technologies is trading 7.69% up at $1.40 after closing at $1.30 on September 21, 2026, with no clear company-specific catalyst or overnight announcement explaining the pre-market rebound.
- The latest identified company news was a September 17 Southern California distribution agreement for OneRF, which predates the move.
- The broader market is modestly higher, but that does not clearly explain the stock’s gain.
