With approx 2,800+ optionable stocks, the law of averages dictates that some of them are going to to expire very close to a strike price and some will expire right on the strike. If you really want to impress me, tell me which ones will be pinned a week before expiration. Then I'll believe.
I guess he picked QCOM because of the high volume and open interest on the 40.00 calls and puts, so I assume selling them @ $0.42 and $0.55 is a sure bet. We will find out Friday. But as spindr0 pointed out of 2800+ stocks many will be "pinned" to a strike price.
This topic comes up all the time there is nothing you can do or say to make anyone change their mind when they believe that PIN is the norm. Lets see them sell the straddle.
Hopefully this puts the PIN arguments to rest... i doubt it as many will still look for that Holy Grail...
Some stocks get pinned, some do not! I have devised a strategy to trade it. What I will say about my strategy is that I look at more then just options data.
