In mid-July 2008, the SEC announced emergency actions to limit the naked short selling of government sponsored enterprises (GSEs), such as Fannie Mae and Freddie Mac, in an effort to limit market volatility of financial stocks. But even with respect to those stocks the SEC soon thereafter announced there would be an exception with regard to market makers. SEC Chairman Cox noted that the emergency order was "not a response to unbridled naked short selling in financial issues", saying that "that has not occurred". Cox said, "rather it is intended as a preventative step to help restore market confidence at a time when it is sorely needed." Analysts warned of the potential for the creation of price bubbles.
