I already had a pretty sizable position in the 22 puts (up almost 250% already, and the big lockup isn't even here yet!), but I couldn't resist buying more 19.5 puts today. My original strategy was just to load up next Tuesday afternoon, but it doesn't seem likely this will be positive monday and tuesday.
Still will be making more purchases on Tuesday. It seems like a 10+% drop may be very likely. :)
