Anyone stick with YMAT through that long midday grind?

Anyone stick with YMAT through that long midday grind? The late move on YMAT was easy to miss if you'd written it off after premarket. It had already hit $3.28 before Stock Pulse mobile app flagged $1.88 at 8:54 AM ET. Then it dipped below the alert and spent hours going sideways. The recovery took most of the day: around $2.28 at the close, then $2.38 at 5:02 PM. That's about 27% above the alert, with 132,000 shares in that peak minute. I couldn't find a fresh company announcement explaining September 9's move. J-Star did file a $150m shelf registration on September 4, though. That's proposed capacity for future securities sales, not $150m raised or proof shares were sold that day. For anyone who traded this: what kept you interested through the quiet stretch? Or did you only come back when it started moving in the afternoon? \[September 4 filing\](https://www.sec.gov/Archives/edgar/data/1875016/000149315226041488/formf-3.htm)
