It's possible. I think gains will be attenuated by the fact that insiders are looking to get out at a *fair* price.
Normally we would expect a bit of a retracement on such an up move on technicals- as sleepy investors wake up and decide to sell at these higher prices.
However, the market has already been bracing for a lot of supply. So I think any retracement tomorrow will be more limited than folks would otherwise expect. Normally you could expect as much as a 6% down move tomorrow, but I don't think you'll be down more than 2% and could close up.
