I doubt there will be a massive sell off tomorrow, it will take several days for most of the new shares to be issued, I don't look for much trading til next week. Then it will depend upon what the actual share count was, if it was in fact under 200 million presplit, don't look for much liquidity and expect it to be very volatile.
A tornado is like a stock, it takes just the right conditions to form a huge one but once it forms, nothing can stop it!
