Shares of

Gander Mountain

( GMTN) were among the

Nasdaq's

losers Wednesday, falling 9% after the outdoor specialty retailer posted a wider-than-expected second-quarter loss and said that comparable-store sales for the full year would be below previous guidance.

The company reported a loss of $10.4 million, or 73 cents a share, on sales of $173.6 million. Analysts polled by Thomson First Call were expecting a loss of 16 cents a share on sales of $172.8 million. A year ago the company posted a loss of $3.9 million, or 27 cents a share, on sales of $128.1 million. In the most recent period, Gander reported a 4.2% decrease in comp-store sales, compared with an increase of 1.8% a year ago. "While we were disappointed in our comparable-store sales performance and loss," the company said, "we had anticipated incurring a loss in the second quarter because of seasonality of our business."

Looking ahead, Gander reiterated its belief that sales would exceed $850 million during fiscal 2005. Comp-store sales, however, are now expected to be flat, which is below previous guidance of up at least 2%. Analysts are expecting 2005 sales of $861.4 million.
