were on plan for the first week of February.

At J.C. Penney, comparable department store sales, which track sales at stores open at least one year, were on target for a low-single-digit decrease in the first week of February. The most popular items were home furnishings and women's apparel and accessories. At the Plano, Texas-based company's catalog division, sales were on plan for a high-single-digit decline. Drugstore sales were on plan for a high-single-digit increase. The company's shares were down 15 cents at $14.76.

Other major retailers held back their weekly sales reports ahead of Thursday's release of full monthly sales data.

Wal-Mart

(WMT) - Get Report

, the nation's largest retailer, has said in past weeks that it is on plan for a mid-single-digit percentage gain in comparable store sales at both its Wal-Mart and Sam's Club divisions. (Wal-Mart counts five weeks in its January sales period, while most other retailers, such as J.C. Penney, count four.)

Most major retailers will report monthly same-store sales figures on Thursday. These will be closely watched to gauge the behavior of the nation's consumers in the wake of a disappointing holiday sales season.
