Tomorrow's open will likely be above $13.50 with a spike caused by any remaining short shares. The stock will then settle down and likely trade around $13.50 until the end of the year when the sale is complete, at which time, your shares will be exchanged for cash if you still have them.
I'm also curious what will happen. I'm a late investor in this stock. I barely purchased 500 shares 2 weeks ago. I'm only up $126, heh. Curious If i should just keep it or dump it and reinvest that money elsewhere like cldx.
