It looks like the stock will be down again tomorrow so since there are only 2 companies that make airplanes, I will take a chance that BA will be in business, even though they may have to give up on the Max.

So I am looking at the December 2020 puts which is a year away. Fidelity will only require a margin of $3,520 per contract and as of tonight you could sell the 250 puts for 11.95 or better tomorrow. I calculate that as a 36.5% return on margin for the year.
