In an interview with "The Washington Post" in late December 2008, Cox said, "What we have done in this current turmoil is stay calm, which has been our greatest contribution—not being impulsive, not changing the rules willy-nilly, but going through a very professional and orderly process that takes into account unintended consequences and gives ample notice to market participants." Cox added that the Commission's decision to impose a three-week ban on short selling of financial company stocks was taken reluctantly, but that the view at the time, including from Treasury Secretary Henry M. Paulson and Federal Reserve chairman Ben Bernanke, was that "if we did not act and act at that instant, these financial institutions could fail as a result and there would be nothing left to save." In a December 2008 interview with Reuters, he explained that the SEC's Office of Economic Analysis was still evaluating data from the temporary ban, and that preliminary findings pointed to several unintended market consequences and side effects. "While the actual effects of this temporary action will not be fully understood for many more months, if not years ... knowing what we know now, I believe on balance the Commission would not do it again."
