But, why would you even want to roll soon ? I'm planning to sell all my 2/15 (5%) and 3/15 (95%) calls within days after ER and then wait for the inevitable dip to "roll".
After Q3 I got sucked into thinking there is actually a "squeeze" possibility that I didn't want to miss out on - so invested some of my profits from the sale of Q3 calls on stock + Leaps + 3/15 calls (at "low" SP of 353)
There was a squeeze after the Q3 ER. Short interest dropped a lot.
The issue is that one can't know when the market has fully digested the implications of the ER. Hence the reason I want (like you) to retain meaningful leverage for the first few days, but then roll (reducing but not eliminating leverage) to more distant expiries. Whenever I feel confident that the news is fully digested I'll further deleverage. I don't want to be highly leveraged for more than a few days, however.
