Sono-Tek is trading at $6.70, up 7.98%, with no confirmed explanation for the October 5 move.
- No new company-specific announcement explaining the move surfaced in available reporting. The latest major catalyst was the September 30 announcement of approximately $7.19 million in clean-energy orders; reports linked it to the earlier surge, not specifically to October 5.
- Major indices are mixed, with none moving more than 0.5% in the same direction, so broad-market sentiment does not clearly explain the gain.
