Neuroone Medical Technologies is trading 13.78% up at $2.31, with no company-specific announcement or late-breaking catalyst identified.

  • It closed August 21, 2026, at $2.03 after a 5.58% regular-session decline.
  • The move appears isolated amid modestly positive broader markets; recent volatility followed August 13 fiscal Q3 results.
  • Available market coverage reported no press releases, and confidence is low because the immediate catalyst remains unclear.
