What are you going to do if INTC closes above 20 at Dec exp? You may end up having to pay up to 4 separate commissions for this strategy.
Consider doing the Dec 18/20 call spread for a debit of 1.43
Your effective cost per share would be 19.43, which is 0.23 below the current pps of 19.66
You can do this as a spread trade. If you decide to do this, then do at least few of them to make it more cost effective.
