and generally people are wrong, but I can tell you without a doubt books got destroyed yesterday.
A lot of time people just assume, but everything, and I mean everything hit. Every ML fav hit every teaser hit, there were a few buy backs they hit.
I would say yesterday might be the worst day the books have seen this millennium. It really was that bad.
So if you lose money yesterday you can kid yourself and say "I must be sharp because all the squares cashed".
