I am a bit confused by the latest sell off.   Everyone can't make money on these swings, and I would bet that most lose it.   So why do they keep trying?   It's not like there has been any kind of bad news to induce selling, and we all know how much people will be willing to sell for on Monday or Tuesday.   I can't figure out why so many want to sell at the current low.

Edit - I meant buy not sell.   I am up too late
