i would love to believe that but I have a theory that these banks are able to peek in to accounts and see who is short and who is long and what percentage. People keep scratching their heads at how the market can keep going higher when people keep investing in gold or going short. The only answer that I can see is that these guys are playing poker and they know everyone elses hands. They then know accroding to all their algorithms what type of bet(howe much they need to raise the makret) in order to get the retail shorts to fold(cover) their bet. Once the retail guy covers at a loss, they notice because they can see the hand, and then start selling the stocks. Big reasion why retail never wins in the market if they are trading. They are playing a rigged game.
