Retailers reported mixed November sales Thursday, with disappointing results from

Wal-Mart

(WMT) - Get Report

overshadowing strong gains at other big chains ahead of the holiday season.

According to Ken Perkins, president of research firm Retail Metrics, 56% of retailers missed expectations for the month, while 44% of them beat forecasts.

"It certainly casts a little more doubt about how robust the December shopping season is going to be," he says.

Wal-Mart, the world's largest retailer, confirmed that same-store sales for November slipped 0.1%, missing Wall Street's forecast of flat growth. The company said its home and apparel business has been challenging and predicted this trend would continue throughout the fourth quarter.

For the key December holiday period, Wal-Mart expects same-store sales, or sales at stores open at least a year, to be flat to up 1%.

"Factors impacting our December comparable-store sales estimate include the impact of the hurricanes from last year and continued challenges in our apparel and home business," said Chief Financial Officer Tom Schoewe in a statement. "We expect to see improvements in our apparel and home categories by spring."

"That number for December is not a good thing at all," Perkins says. "It basically means a flat holiday, which is not very encouraging for them or their investors."

Perkins noted that Wal-Mart's negative presence was a big drag on the overall same-store sales figures for the month.

Excluding Wal-Mart, same-store sales were up an average 4.2% of the 49 stores that reported Thursday, Perkins says. If Wal-Mart's results are included, that figure is halved to 2.1%.

Wal-Mart's biggest rival,

Target

, met expectations with a 5.9% rise in November same-store sales. Total sales climbed 12% to $5.12 billion from $4.58 billion.

In department store retailing,

Federated boosted its same-store sales guidance for December to an increase of 5% to 8%, compared with previous guidance for an increase of 3% to 5%. Same-store sales for the fourth quarter as a whole are expected to increase by 5% to 7%.

AnnTaylor

reported a same-store sales decline of 4.3%, worse than analysts' expectation for a 2.3% drop. Sales climbed to $186.4 million from $182.5 million last year.

Ann Taylor said trends picked up in the latter part of the month and it had a strong performance for Black Friday. The retailer said new merchandise arriving at stores this week should help build momentum in the holiday season.
