occurs and not these little 1-2% or 150--250 drops, will that shorting on downtick rule carry more weight? For the record, I think the DOW will bounce back up after some smoke clears... But if that REAL sell off occurs say in October and were at 13,400 and we drop 900 points, that short tick rule is partly the catalyst for added downward pressure? I say a crash doesn't occur since everyone is anticipating another 1987. Just not that easy...bloated market still has another run in her(but I hope not)
