The company reported earnings of $11 million, or 2 cents a share, on revenue of $1.62 billion. Analysts polled by Thomson Financial expected earnings of 10 cents a share on revenue of $1.73 billion. During the year-earlier quarter, the company posted a loss of $12 million, or 4 cents a share, on revenue of $809 million. Shares closed down 72 cents to $8.24.

The company also announced a stock repurchase plan of an additional $1.5 billion. The company only had some $19 million remaining under its previous share repurchase plan. "The company has a strong balance sheet and generates significant free cash flow, allowing us to invest in our business, consider other alternative investment opportunities, pay down debt, and repurchase our shares, each as appropriate given our objective of increasing shareholder value," Sears said. Shares closed up $7.45 to $140.55.

Shares of Diebold ( DBD) fell 4.4% after Keybanc downgraded shares of the maker of electronic voting machines to hold from buy. The firm said that Diebold's election business faces pressure.
