According to a study recently published in the Journal of Accounting Research, journalists are a lot better, or at least faster, at spotting signs of accounting fraud and corporate shenanigans than the SEC. Harvard Professor Gregory Miller measured the frequency of reporters beating the SEC to the punch in uncovering fraud and found that in roughly one-third of the 263 cases of accounting fraud confirmed by the SEC between 1987 and 2002, members of the press alleged wrongdoing before the SEC or the company announced any investigation.

The Columbia Journalism Review sums up the findings nicely: "And while beating the SEC to an investigation is like beating Porky the Pig in a bicycle race up the Alps, we concede it's not nothing."

I e-mailed Marketwatch columnist Herb Greenberg (Full disclosure: He's one of my heroes.) about the findings, because he was the only journalist to have proactively uncovered a case of accounting fraud before the SEC more than once; he's done that five times.

Given the relative speed with which journalists uncover fraud, I asked him whether the SEC could learn anything from the methods employed by journalist-gumshoes. Greenberg dismissed that idea saying that "There's a difference between reporting a story and formally investigating and finding legal fault .... No, nothing they can learn."

He added that that much-maligned band of investors known as short-sellers are often sources for investigative reporters, calling them the "first line of defense for investors because they're putting their own money on the line." But he said that really good information usually comes from "former employees, analysts, and mutual fund managers who have SOLD stocks for reasons other than valuation."

Herb Greenberg's Weekend Investor column focuses on the need for investors to be more skeptical or, as he calls it, detective-like. By looking deeper into the numbers than just the earnings per share or revenue growth, you can sometimes uncover signs of trouble before most Wall Street analysts do. And with increased disclosures as a result of the Sarbanes-Oxley Act, there may be more red flags to be found than ever.

Unfortunately, I suspect very few investors have the skills to read a 10-K or 10-Q critically. Most of us just take everything at face value. But, learning a little bit of "forensic accounting" is a lot of fun (you really do feel like a detective) and may help you notice some danger signs. Here are my favorite books for digging deeper into financial statements and seeking out signs of fraud or misrepresentation:

Financial Shenanigans: How to Detect Accounting Gimmicks & Fraud in Financial Reports by Howard Schilit. Probably the best book on accounting fraud.

Quality of Earnings by Thorton O'Glove. I found this one dry and boring, but it's written by one of the first experts in the field, and contains some great examples.

The Art of Short Selling by Kathryn F. Staley. While not exclusively about accounting fraud, this contains some interesting stories of companies that were engaging in creative accounting. And, if you become an expert on creative accounting, short-selling may be a way to a profit from it.
