Tempur-Pedic (NYSE:TPX)












Cliffs Natural Resources (NYSE:CLF)

Overseas Shipholding was the market's biggest loser, shedding nearly two-thirds of its value after revealing that it's considering strategic alternatives including the possibility of filing for bankruptcy reorganization. Naturally, Moody's and S&P downgraded the company's credit rating after that.

Tempur-Pedic was as lumpy as the mattresses it seeks to replace. The premium bedding maker posted another disappointing quarter, slashing its top- and bottom-line guidance for the entire year.

Shares of Crocs slipped after the maker of resin footwear missed Wall Street's sales targets. Weakness in once-strong overseas markets also finds Crocs hosing down its projections for the balance of the year.

iRobot is malfunctioning. The maker of home and defense robotics posted better-than-expected results for its most recent quarter. iRobot has been very good on that front. However, weak defense spending is forcing the company to forecast near-term weakness in its business.

Finally we have Cliffs Natural Resources. It isn't easy to be a miner when the commodity that you are extracting -- in this case, seaborne iron ore -- sees its average selling price fall by more than a third over the past year. The result is that Cliffs margins are getting crushed.
