I think you should be fine on that one, $40 premium, and if you are assigned just $1980 to make back -
Given the ER and AH movement doesn’t look like you will get assigned pretty decent IV play.
I think the biggest part of CSP’s is asking yourself if I get assigned do I like this for the long term and having a plan - is it to make a quick buck in and out or is it work down the cost of entry and to continue to sell calls for life.
Ya that would suck, any CSPs I sell and get assigned on - if I can even them out in 6 months I call that win - since after that it is basically free money for life.
If you sell a 30% OTM put on an earnings play and it blows up, you should probably take the L and move on. Do you really want to baghold some steaming pile of shit that missed bad enough to dump > 30% in a day?
Keep in mind if you lose you’re not losing your max loss, you’re losing (Strike price - premium - stock closing price on expiry)*100 per contract assuming you short sell shares on expiry to offset the assignment.
Oh, and don’t ever do this on a bio tech. Those can dump like 80% if they report news that the drug they spent the last 3 years (and all their money) on got rejected by the FDA. And that kind of thing happens on a regular basis.
