Does anyone here like to do short straddle on expiration day to try to capture the remaining premium decay by the close? You should get a pretty decent idea where the pin action is around noon on expiration Fri. I shorted 5 GOOG July 390 Call and 5 July 390 Put for 3.9 around 1pm and covered the trade at 3:58pm for 0.2. Not too shaby for 3-4 hours of work.
