Today's open in financials is a great example of what happens when shorting is banned - no one can stablise the market when the majority want to buy and few longs want to sell. So what do we see? Financials opening up at crack crazy prices. No one with offers to keep a lid on the price ramp. The SEC unintentionally just gave a real-time lesson in economics 101. Shame they are too fucking dumb to learn - they probably don't even realise anything wrong happened.
