Not positive in my opinion. Like sort of clandestine, secretive, and devious. If it is based on inside information it is illegal. I think it's inter-market makers continuing to juggle and clean their books for the upcoming new rules starting Monday. I think that a lot of them had built a big short position by abusing their own rules on covering. Now who is on the sell side ?? Perhaps the Financiers. The trades are obviously pre-arranged. And who has large amounts of stock ?
