Okay, update. This morning I had solicited advice on what to do with my first option purchase as things were moving fast. I had bought a single $750 contract on 1/16/20 for $2.20, expires 2/21/20. SP was climbing into the 700's pretty fast and I wasn't expecting the possibility of it actually being ITM 2+ weeks into it. Never the less, didn't get any advice as the SP exceeded my $752.20 break even. However, my account showed a 2,800% ish gain so I sold it at $60 for an almost $6k profit on $220 in 18 days.
My understanding is that as the expiration date approaches, the theta decays exponentially so I decided to take the sure bet rather than expect the climb to be as meteoric as these past 2 weeks have been. Obviously no one can predict what the next 2 weeks will do but did I jump the gun here and miss out on potentially more significant gains? I keep hearing about after being ITM for too long, there are diminishing returns. Would that have even been an issue with such a short term option?
