When it comes to defending themselves against accusations of wrongdoing, management teams and their complacent boards follow a well-worn routine. Their immediate reaction is to issue a blanket denial and announce that an independent committee of directors will investigate the accusations. The committee duly appoints an independent law firm to oversee the investigation, and the consulting arm of a Big Four accountancy to pore over the books.

Too often, such investigations are worthless endeavours that lead to more pain for investors. Frequently, companies are exonerated by their boards but subsequently tumble into bankruptcy or announce earnings restatements or evidence of other serious problems.

There are no better examples than the numerous companies – based in China and listed in the west – accused of fraud by short sellers, including Muddy Waters Research.
