I do these videos unscripted, so forgive me if they go astray. I forgot to mention. Fridays volume was only 6M shares. You can bet 80% of that volume was related to option hedges coming off and going on as people open and closed positions.
Just noticed. That chart I showed, there was no Monday trading, that 1st day was a Friday. Awe, what are you going to do. Same premise applies :o)
