Learned something new and useful from Croock.
Nasdaq lost today 2% and he expects it to go down next week.
So by buying puts for QQQ he protects himself.
Invesco QQQ Trust Series 1 seems to be the best solution to short the Nasdaq without actually working with the index itself.
It’s much cheaper that way.
If it happens it can cover my OSTK loss if any; and if it doesn’t happen I can close it tomorrow or Monday with some loss.
I should look for an AEX ETF, see if exists.
