Kim, when backtesting the pre-earnings calendars, is the idea to track the price of the ATM spread each day in the runup to the historical earning date, whatever the ATM strike price happens to be on a particular day?
For example, FSLR calendar: the underlying might be 60.00 on Monday, 62.50 the next day and 65.00 the next day etc -- do you look at the price of the 60 calendar on Monday, the 62.5 calendar on Tuesday and the 65 calendar on Wednesday?
