A DealBook piece looks at David Einhorn's very public battles with Allied Capital (NYSE: ALD) and Lehman Bros. (NYSE: LEH), both of which he is short and accused of accounting chicanery. Einhorn's willingness to "talk his book" has generated controversy. Steven Davidoff writes that "Many short plays are enhanced through rumor and innuendo spread by those self-same shorts. Needless to say, these whispers are sometimes unfounded but can do real harm to a company's share price and the company itself."

In his email newsletter, fund manager Whitney Tilson slams this comment: "Hmmm... How many is "many"? More than one? A majority? 99% of the rumor and innuendo in the market I see is on the long side! The shorts I know, on the other hand, perhaps because they're often falsely accused of spreading "rumor and innuendo", bend over backwards to be open and factual."

This is exactly the point. What is the ratio of "pumps" to "bashes"? When Einhorn goes on CNBC and trashes a stock, it's a national story. That's because it's incredibly rare for anyone to go on CNBC and slam a company. The extent of the skepticism we usually hear in the financial media is "overvalued" or "tough prospects."

So I say to Einhorn and Co.: Keep doing what you're doing. Differing opinions, and especially unpopular ones, make for a better market.
