Shares of

GameStop

(GME) - Get Report

were among the

NYSE's

winners Thursday, jumping 12% after the video-game retailer posted solid December sales and lifted its fourth-quarter and full-year financial guidance.

The company posted an 8.7% jump in December pro forma same-store sales, and said results were strong across the board. "This year's holiday performance was particularly notable as GameStop did a great job of working our business model and generating strong contributions from all categories of the business," the company said. Total sales for the nine weeks ended Dec. 31 came in at $1.35 billion, up from $577.7 million a year ago. Much of the increase came from the addition of Electronics Boutique, which GameStop acquired in October.

GameStop now sees fourth-quarter earnings of $1.06 to $1.08 a share, up from its previous guidance of 98 cents to $1.02 a share. Analysts polled by Thomson First Call are expecting fourth-quarter earnings of 98 cents a share. For fiscal 2006, the company sees earnings of $1.75 to $1.78 a share, up from an earlier guidance of $1.65 to $1.70 a share, and above the $1.66 a share that analysts had been expecting. Shares were trading up $3.94 to $37.39.
