Shares of Timken ( TKR) were among the NYSE's winners Thursday, rising 9.3% after the company raised its fourth-quarter earnings outlook.

Excluding items, the steel producer now expects earnings of 39 cents to 44 cents a share, up 10 cents from its previous guidance. Analysts polled by Thomson First Call had been expecting earnings of 34 cents a share. Strong end-markets, increased productivity and increased material cost recovery led to the revised outlook. Shares traded up $2.16 to $25.50.

Red Robin Gourmet Burgers ( RRGB) fell 3.8% after the company cut its fourth-quarter earnings guidance but lifted its sales forecast slightly. The restaurant operator now expects earnings of 33 cents to 34 cents a share, down from previous guidance of 35 cents to 36 cents a share. Sales, meanwhile, are now expected to be $98.9 million, up from previous guidance of $97 million to $98 million. Analysts had been expecting earnings of 38 cents a share on sales of $100.1 million. The earnings revision was attributed in part to higher tomato costs and expenses related to the Sarbanes-Oxley Act compliance. A one-time charge related to rent expense knocked a penny off earnings as well. Shares traded down $1.79 to $44.82.

Shares of Borders Group ( BGP) rose 5.8% after the bookseller raised its fourth-quarter earnings estimate to the high end of its previous range. The company now expects earnings of $1.60 to $1.62 a share, up from previous guidance of $1.55 to $1.62 a share. Analysts had been expecting earnings of $1.58 a share. The company expects fourth-quarter sales of $1.2 billion, up 4.8% compared with a year ago. Holiday sales, according to the company, were a "bit better than expected in Borders superstores," and were "driven primarily by strength in book sales." Shares traded up $1.38 to $25.12.

The Sports Authority ( TSA) rose 9.1% Thursday despite a warning that fourth-quarter earnings and sales at the sporting goods retailer would be lower than expected. The company now expects earnings of 90 cents to 95 cents a share, down from previous guidance of $1.08 a share. Analysts had been expecting earnings of $1.06 a share. "Prior to Christmas, our planned sales improvements in the winter product categories, in most of our cold weather markets, did not materialize, as these markets experience significantly less snowfall amounts than normal," the company said. Sales of hunting and camping merchandise, along with holiday-driven categories -- such as table games and scooters -- delivered below-plan results during the quarter as well. As a result, same-store sales are now expected to be down 2%. Previously, the company had expected sales to be flat. The company did add, however, that as colder temperatures "returned and snowfall occurred post-Christmas, we experienced improved sales in the winter product categories." Shares traded up $2.23 to $26.70.

Shares of Kenneth Cole Productions ( KCP) fell 7.9% after the footwear and accessories company lowered its fourth-quarter earnings and sales outlook and warned that results would be below analysts' forecasts.

Analysts had been expecting earnings of 56 cents a share on sales of $139.7 million. Kenneth Cole said a challenging December, particularly in its consumer direct business, led to the fourth-quarter revision. Shares traded down $2.31 to $27.01.
