I dont know about the 28th (reballancing day?) but my mentor said never make a move on monday or friday. I'm not really one for superstition but ....
Heck of a day ... not a single sector green. Not a single world market green. Money going somewhere but looking around, commodities red except oil (a hair green) ... everthing is red everywhere. Vix is up. Fut down 100+. It's not going to be a good Friday for QQQ or anything else it seems. Well OK, maybe GME and WSB green. Where is the big money moving to?
