The December 17 – January 15 call spread could have been bought for as little as 0.35-0.40, but we’ll use the 0.55 price advised when I recommended rolling our call spread out to January. This means we are long eight December 12.50 calls effectively for a 0.40 debit (i.e., long stock for 12.90), and short eight January 17 calls for 0.80. Don’t worry if you didn’t roll the spread;  the goal in any case is to come out of next Friday’s expiration with 800 shares of stock to hold as a long-term position. The short January 17 calls will simply give us a little downside protection at a cost of limiting our near-term upside potential above $17.80.
