What on earth do I buy... Nov 200's? Nov 185s?
The veterans in this playground will surely point you in the correct direction, but here's the way I look at it.
Firstly, I'm assuming you mean calls and that you expect the stock to go up to 200 sometime before Feb 2014.
Secondly, I'll assume you want to do Nov because Oct is "too soon / expiration too close" and Dec is "too long" to keep the money tied up.
Thirdly, I'll assume you asked this question before market open and the stock is at $173.31/sh.
This leaves a range of calls to consider but let's simplify to 3: Nov 170, Nov 185, Nov 200.
Nov 170: You'd be splitting your investment between time value and share value. This is like buying a mixture of calls and some stock, from my perspective. I generally prefer "pure timevalue investment" when buying calls/puts, and thus I typically won't give these much thought.
Nov 185: $12 above the market and cost $2-$4 (rough estimate, don't have yesterday's numbers handy)
Nov 200: $27 above the market and cost $1-$2 (rough estimate, don't have yesterday's numbers handy)
So your decision is: Do I want to watch the stock closely and be ready to make a move very quickly? If yes, then the higher risk of the 200s has a higher opportunity for reward. If no, then the lower risk of the 185s is more appealing. Note that (using the numbers above) you can buy twice as many Nov 200s as Nov 185s so movement in the 200s is felt (loss or profit) far more quickly.
