Personally I would say the time for buying puts was before Xmas, but easy to say that in hindsight, although I did say to at the time as well
Between then and now I did buy 100x July +p150 and have been selling against them quite profitably until this last week, well "selling against" isn't strictly true, all my puts are CSP, but it's nice to have the extra safety-net
Of course if you you buy them and the SP tanks then you'll feel very smug... another possibility it to sell some DITM calls, if you're really, really convinced it's going down - the plus of short calls is that you can roll them, long options are lost when the price goes against you
My personal plan from here is to get out of the 43x -p200's, and reposition to OTM puts against 50% of the long puts, but then if the SP really dumps, sell off the long puts and have the shorts flip to fully CSP - there comes a point where the long puts are no longer providing protection, but need to be cashed-in, likely if they go ITM I'll do it...
