Not advice!!! But you sound like you have a lot of them. I've seen and used a technique of spreading the risk up and down the price range and time duration. So instead of having say 10 700 calls, have 3 680s, 3 700s, and 4 720s (not linear in price, hence having the most at a higher strike price.).
I do this with time as well, but in this case, I'm not sure what's going to happen at that exact time (after hours on the 18th through before trading on the 21st). If there is a spike at 4pm and after hours on the 18th, and most people are predicting a drop after inclusion, having the options that expire the next week (12/24 due to Christmas) might be a detriment.
Also, if I didn't use the right language to say "Not Advice!!!", please let me know so I can correct it. It's crazy that the world we live in we have to give all these disclaimers for normal folks not to get blasted, and yet if you have a lot of money, it seems you can do no wrong and get out of anything. Oh well, not to get OT!
