The Five Dumbest Things on Wall Street This Week

5. Working Overtime

A little routine paperwork is turning into a big mess at Office Depot (ODP Quote).

The Delray Beach, Fla., office supplies company saw its shares plunge 14% Monday after Office Depot delayed its third-quarter earnings release. The company, whose slogan is "taking care of business," hinted at possible accounting problems -- prompting a wave of downgrades by analysts concerned that an earnings restatement could be on the way.

"The delay is due to an independent review by the Audit Committee of the company's vendor program funds," Office Depot said Monday morning. "The review relates principally to the timing of the recognition of certain vendor program funds."

Sounds like Office Depot may have been taking care of business a little too well.

Dumb-o-Meter score: 80. "Perhaps the most favorable outcome for the stock would be a transformational event," one analyst decisively concluded.
