Quote from m22au:
I don't quite understand your idea of "asking for cash settlement". To me that sounds like a negotiable contract.
I believe that stock options are much more simple than that. A put buyer has the right but not the obligation to sell. The put seller, if assigned, must buy at the strike price.
However, if the stock goes to zero, then how does an uncovered put buyer (ie, long put + no position in stock) deliver the stock to the put seller?
When you excersize an option contract, you can instruct your broker for a cash settlement.
A lot of times this has to do with margin and buying power.
Suppose you own 1,000 calls on GOOG at 400. At expiration its at 450.
You're making 50 points.
However, if you chose standard excersize, you will have to shell out 1,000 * 400 = $400,000 to get this position. Then you will sell it for 450,000 and make 50 k profit
Now suppose you bought your 400 calls when Goog was at 100 and they were WAY OUT OF MONEY and cost you like $3.00 per call.
you used 0 margin (cuz you cant) and you bought $3,000 of the stuff.
ANd, you only have 30,000 in your account.
How are you supposed to excersize your call when you need 400k to acquire that position?
Answer: cash settlement. Broker simultaniouslyu excersizes and sells your position for a cash settlement.
