so start buying SPY 2019 may puts and ladder them out for a year until may 2020?  How long of a confirmation on the 2/10 year inverting should we look for to hold (like if it stays inverted consistently for 1 month-2 months then start buying puts?).  yes I realize it's an indicator and not the full picture.

I've seen people say 30 to 40 days of inversion. Keep in mind we are also coming out of an environment where rates were kept artificially low for a long time so the inversion could mean nothing this time around
