The markets are just fixed. They all follow the same patterns at the exact same time, doesn't matter how unrelated the stocks are. I'm sure it's just some algorithm at work but it has too much Control over the market.
Markets have been running off sentiment rather than business fundamentals for some time. They always do to some extent of course, but particularly right now.
A lot of it is algos and day traders just slicing off profits from the volatility too. There's not some mysterious overlord controlling it, it's just markets at work.
