thats not what I'm saying.
Look at the options volumes on GOOG compared to almost any other stocks [much more]. Then compare the option volumes (at the money) to the underlying stock volume. Doing this simple math, you'll quickly realize that the options trades are moving this stock more than underlying stock buyers in a day like today.
GOOG pins like no other stock I've seen.
today:
ie at 640-660 call october strikes, 82k options
and put strikes 630-660, 122k options
and november options today: 20k options in that same strike range.
lets avg the delta exposure amongst all those strikes to a generous 30. (early in the day you have a lot more deltas than later of course due to fast decay)
224k options * 100 shares * .30 (delta multiplier) = 6.72 million shares out of total already 10.7 million.
Add in program trading from indexes in a high volume day like today, and I bet not more than 1 or 2 million outright shares traded today (versus options hedging stock share trades).
Thats pinning for you.
I'll believe that. It's just that for some reason pinning is this new en vogue subject. I think it's due to Cramer, every month like clockwork, rattling off some arbitrary list of stocks and claiming that they all "have" to get pinned at whatever the nearest strike happens to be, without the necessary analysis.
