GSI Commerce

GSI Commerce Inc.'s (GSIC) second-quarter loss widened as the company's costs offset a big jump in revenue.

Shares of the company, which develops and operates e-commerce sporting goods businesses for retailers and other organizations, dropped 5.8% to $25 after hours as results fell short of analysts' forecasts. As of the close, the stock had risen 65% in the past year.

The company also forecast current-quarter revenue of $280 million. Analysts surveyed by Thomson Reuters most recently projected $273 million.
