The rebound at 10:05 is on very low volume. This can be a manipulation by someone that is holding a large amount. He triggers a price rise by buying a few 100 shares to encourage others that there is a price rise under way. Then as other buyers jump in the original investor sells it s shares at a higher price and gets out. Then the price sinks again. SUTR will be very volatile today and some new investors might be taken advantage of.
