Do Pay Attention To the Close

I'm really starting to dislike op-ex Fridays, however the last several I've noticed that we tend to break free from the monotony of the pin and I assume that's because most option contracts have been settled, I don't know bout you, but I'd get a call about 2:30 from my broker wanting to know what I was going to do with a contract, if I said I'd wait it out, I'd get a few more calls. The point being, I think late in the day enough contracts have been settled that they can move away from the pin, if I recall correctly that was what was behind that AAPL Friday call that cashed out the next Monday at 100 and 115%.
