Monday markets were way down, Tues way up, and today even more way down. Individual stocks are acting so weird there's speculation of market manipulation being discussed on Bloomberg and elsewhere. I have 2 stocks that announced earnings after the bell last night, both beat across the board, and upped their guidance. One was up 5% after hours, the other 8%. Today the first one is down 4%, the second one is down almost 9%! There's no new information out but one of those companies that does short selling reports has apparently targeted both of them, I Robot(IRBT) and Illumina(ILMN) and issued old reports, again, and there's a big sell off of both. There's some speculation shorts are actively targeting stocks recommended by Motley Fool because those 2 and Shopify have all recently been hit by short seller reports and all 3 are recommended by MF. A guy on Bloomerg said it's crazy, if I were an investor I'd buy all 3 stocks based on facts but given they shouldn't be falling now, there's no way to know how much more they could fall.
