As a brief update - these numbers from earlier today were when the shares were down about $7. At this point, they are down about $80, and it occurred to me that I left money on the table by closing as early as I did. I thought I would provide some updates on actual numbers, to help people inform their intuition of how option premiums can change (in this case, day after earnings, with expiration tomorrow - a pretty rare and extreme circumstance). I closed the 1700 calls at about $7. They are now trading at about $1.50, so the next $83 drop in share price would have gotten me another $5.50 in premium reduction (high %, small actual). The 1850s calls were closed at $1.50. Another $83 drop in the share price has lowered that premium to $0.40. On balance, I did leave money on the table, but I also eliminated the risk at that point that the share price would suddenly reverse and go up $100 . And it wasn't much money that was left on the table.
