For those who don’t think that the suspension of the uptick rule or unfettered naked short-selling are to blame for the downfall of Bear Stearns, Lehman or AIG, as we have claimed on over and over again on Mad Money, here’s an edited version of a comment I posted over on Kevin Drum’s Blog at Mother Jones

First, the uptick rule, which forced the shorts to wait for a buyer who was willing to pay a higher price than the last trade for a stock before they could short it again, slowed things down. It made it impossible for shorts to jam stock down with endless selling, because the stock had to go up a little first, and if it didn’t, you couldn’t short it—so the shorts could only push things down so much. Without the rule, it’s much easier for the shorts to hit stocks down and create a lot of fear, which causes more selling, etc. Longs don’t have the same ability.  You could bid a stock up in the hopes of attracting momentum buyers the same way short-sellers knock ‘em down, but I think fear is a fundamentally more powerful force than greed, which is one reason we need rules that prevent unfettered short-selling.
