nahid, all February options no matter the strike expire for trading at the end of today and the actual options expire tomorrow at noon. Any after hours trading on the stock can impact options and whether they are automatically exercised or not. Anyone can also manually choose to exercise or not exercise with their broker as well.
So Corey, say you sold a $10 put in XYZ and on opex the underlying closes at $10.50 and the put expires worthless. So you think you are golden, but then AH XYZ reports their CEO is stepping down and the AH plummets to $7. Do the put buyers have the right to put the stock to you @ $10 until Noon Saturday?
No, this strange. The call option doesn’t worth any anything no matter what strike price is. I haven’t seen like this before. It is like people have Skull Candy stock and they sell the call options to protect them are winner. Look at the asking price in Yahoo under option tab. I don't know if this is legal.
