I actually just bought a few $650s expiring this week, right before it broke through $620.
Sold 3/7th of this position for an ~2.5x gain. Using it to cover tuition fees and living expenses for next year.
I'm letting the remaining 4/7 ride for now. IBKR gave me an extension on liquidating this position (that is too large for me to exercise on margin) until 15:45.
I'll either have to sell or roll-over before then, or I might contact the block trade desk to see if I can arrange for them to sell these calls in the final 2 minutes.
