Short sellers took a lot of heat during the 2008 financial crisis and the fingers are pointing in their direction again in this latest bout of economic anxiety and market volatility.
Four European nations — France, Belgium, Italy and Spain — imposed a ban on some short-selling this week.
US regulators imposed a three-week ban on shorting financial stocks during the height of the 2008 crisis and there's been some speculation that they could do it again now if worries about the banks really escalate.
Some say bans on short sales don't do any good and, in fact, former SEC Chair Chris Cox once said the biggest mistake of his tenurewas the 2008 ban.
What do you think, should the US bank short-selling again?
