I always found it suspicious that they eliminated the uptick rule shortly after the summer of '07, when the market topped. They claim it doesn't make sense now due to program trading, hmm.
Quote from Big Game Hunter:
I often wonder what happens when you get futures like the YM and ES that can be naked shorted but the underlying DIA's and the SPY's are subject to an uptick rule. It could happen that all of the action in a scenario like that gos to the futures instead of equities for massive naked shorting power. Therefore the rule doesnt work and is a bad idea.
