This is one of the risks of trading options with short term time horizon. I got black swanned or tsunamied or screwed. However you want to call it, it’s a FAIL. Hopefully, it will be a lesson learned.
Fortunately, I also bought some EWJ call options during this catastrophe, and they’re looking pretty good right now. I exited part of the position at a 25% gain and will hold the rest for a longer term bet on the recovery. I’ve still got a long way to go to recoup this loss though.
