Can anyone shed some light on how expiration Friday can potentially affect the market for the underlying? Thanks a lot.
Expiration Friday's Effect on the Market
- Thread starter BobbyMurcerFan

Can you explain the mechanics that cause this "chop"? I heard today that expiration should actually keep the market from dropping too far today and add some support--that doesn't sound like chop to me.
Thanks a lot, I appreciate your help.

No prob & I hope you're getting some cherries coming up 
Indeed.....this AM I was watching TARO,,,,had huge earnings the other day.....trading around $34.50......the Feb 35 calls were asking a nickel.......I had to make a couple of calls and grab a quick serving of cereal and fruit......came back within thirty minutes.....TARO was at $35.50.....those calls were not at .85 cents.......nice return on your money of nearly 20X ........forget vegas....if you want risk reward scenarios that are mind boggling with better odds.,.....take an options expiration Friday.........

also if you do a google search for "pinning the strike" Cramer at TSCM has written a couple of good articles about how options exp effect the underlying. Google should be able to find them. There was one that was especially good that helped explain it to me a few years back.
not as prevalent today though with stock prices so beat down but the PMCS and AMCC's used to dive or ramp 4-5 points into the strikes on options exp day where the big open interest sat back in the bubble days.
Cheers.

Dead on, it's the hedger's activity that drives prices on expiration days. Besides pinning, there is another effect: dynamic hedgers will rebalance their hedging portfolios on these days and when they buy and sell they do it "at the market", they don't wait for a good position to enter/exit that's why S/R lines traders get faked out a lot and there is a lot of chop: GS comes dumping MSFT, 5 minutes later morgan stanley starts to buy MSFT like crazy.
Darn it's slow right now.

when a stock is near an option strike with a large
open interest. There is a tendency for it to be pinned
near the stock. That is the stock gravitates toward
the strike.
so now the question is why?
If we take as a given that:
1. People are risk averse when it comes to keeping gains
2. People are risk loving when it comes to avoiding losses
Those who are long the strike are long the stock above the
strike and short the stock below the strike.
thus with large open interest many take their profits by buying
stock slightly below the strike and then selling it slightly above.
Those who are short the strike don't want to lock in losses by
negative scalping the stock(buying above and selling below)
As it gets later in the day, those long the strike are willing to buy
and sell closer to the strike.
those short get more confident of a pin and thus less likely to
negative scalp.
There is more to it, concerning exercises and assignments.
write me if you are interested.
My two cents
