This is just what I expected. Drive it down and clean out the "masses" of us poor folk, then up 3-5% going into the weekend. They gotta make $$ going both ways. A roller coaster aint not much of a roller coaster if it didn't go up and down, like real fast, so you get all scared. And then "Let's go again"
IMO, Big money, institutional investors, shorts and law firms all work together. Not saying they have nightly planning meetings, but they are like a big swarm of fish, a Conspiracy of shrewd Dunces to bilk the average engineer. :)
