Shares of

CarMax

(KMX) - Get Report

were among the

NYSE's

winners Monday, rising 8% after the operator of used-car dealerships posted first-quarter results that topped Wall Street's forecast.

The company earned $56.8 million, or 53 cents a share, on revenue of $1.89 billion. The earnings per share included a 3-cent benefit related to the company's auto finance unit. Analysts polled by Thomson First Call expected earnings of 38 cents a share and revenue of $1.82 billion. During the year-earlier period, CarMax earned $37 million, or 35 cents a share, on revenue of $1.58 billion. "We benefited from stronger traffic and continued excellent execution by our store teams. Also, we did not see a repeat of the unusually volatile sales patterns that we experienced in the first quarter of the two previous fiscal years," the company said.

CarMax continues to see fiscal 2007 earnings of $1.25 to $1.47 a share, though the company said that earnings could be near the high end of the range if sales trends seen during the first quarter continue. Analysts project full-year earnings of $1.36 a share. CarMax shares were trading up $2.64 to $34.14.
