I'd wait to friday. If no news this week, it will continue to drop back down after today. Don't know how far it will go. Might be worth a shot to hold from buying until Friday, and then you can ride the financial wave next week.
Then again, I think they were holding off from putting out news until S-1 was done. So other types of news could come out any day. But I think all will happen after this week. I'm waiting to buy more on friday; that's what i'm doing.
