Bloomberg’s Jonathan Weil writes a good column. Here he digs into the falacy often cited by executives of failing companies and politicians that short-sellers are responsible for drops in price:

Still Believing

So I asked a Morgan Stanley spokesman, Mark Lake, this week if the company’s executives still believed what Mack said in September 2008 about short sellers to be true. And if so, based on what evidence? No comment, he said. Mack wouldn’t talk either.

I got the same response at a conference in Phoenix last weekend when I posed similar questions to the SEC’s enforcement- division director, Robert Khuzami, who joined the agency about a year ago from Deutsche Bank AG. How are his staff’s short-seller investigations going? Found anything significant yet? No comment, he said. Cuomo’s office didn’t comment either.

My guess for why they have nothing to say is that the whole thing was a farce to begin with. Yet this same urban legend — that mysterious, unnamed short sellers and speculators somehow are to blame whenever markets plunge — still lives on.

In Greece, Prime Minister George Papandreou has tried to blame his country’s budget crisis on speculators who profited by buying credit-default swaps on Greece’s sovereign debt. Actually, it turns out Greece was shorting itself.

Paulson’s Evidence

One of the largest buyers of such swaps was the state- controlled Hellenic Postbank SA, which made a $47 million profit last year after it sold its $1.2 billion position, the Athens newspaper Kathimerini reported a few days ago. The bank’s former chairman later said Hellenic was just protecting Greek bonds it owns against a possible default, not speculating, though that doesn’t change the economics of the trade.

In his memoir, “On the Brink,” Paulson writes like a true believer. “Short sellers were laying the bank low,” he said, describing Mack’s plight a year and a half ago. “But John and his team weren’t about to go down without a fight.” What facts did Paulson cite in support of the notion that short sellers were harming Morgan Stanley, or that they had the capability to do so? None, of course.

Paulson mentioned only one short seller by name in his book, David Einhorn of Greenlight Capital, who shorted Lehman’s stock and warned other investors that the bank’s books were probably cooked. In that instance, however, Paulson said Einhorn was proven right, a point echoed in the findings of this month’s report by Lehman bankruptcy examiner Anton Valukas. (Paulson’s book didn’t name anyone who had shorted Morgan Stanley.)

Wrong Target

Einhorn also was right when he tried to warn the SEC in 2002 about the accounting practices of a business-development company called Allied Capital Corp. The SEC responded by turning around and investigating him, at Allied’s urging, without any basis for believing he’d done anything improper, as SEC Inspector General David Kotz’s office chronicled in a report released this week. Eventually, the SEC let the company off without any penalty, in spite of what the report called “specific, detailed allegations and evidence of wrongdoing by Allied.”

Here’s another idea for Kotz. How about investigating whether the SEC had any reasonable basis for believing Mack’s short-seller story in September 2008 when it acted on his pleas, and whether Mack had any plausible grounds to believe the story himself? Now there’s a probe that might turn up something.
