Quote from FaderTrader:
You've never seen anything gap 30/50 cents? Check out SUN, AHC, PD... I make all my money on being on the right side of these gaps and getting out when there's no catalyst (safety).
Looking at the past week, i haven't seen anything like it. Seems like they are pretty liquid actually, I'd trade them.
Sure there are gaps on the open.
But most day-traders do not hold positions overnight. So it is irrelevant.
It is a risk we all take though. We have to deal with it, if we don't, we will fail if we can't accept it.
I missed a lot of good moves on AAPL chatting it up
