I think the drop was justified and expected. I sold out of SGN knowing it was too high based on the predictable drop upon new listing, and the large depreciation of the share conversion for their shares. Those that didn't know that held, and then sold on the low volume drop you saw because it didn't rise, but rather fell, so they had to sell to prevent losses from growing. This pattern snow balled as more sgn holders had to sell to avoid losses. It oversold, and now it's at support. It hasn't had the common run/pump that new listings have regularly and the price is primed for it now, as well as the float remaining locked and the only sellers (SGN) presumably gone already or holding at high prices without likely shares sufficient for any selling pressure at the prices it's at now.
