Before the bell: Futures decline with the dollar (HRB, MOT, UBS)

Wal-Mart Stores Inc. (NYSE: WMT) shares are trading over 1.1% higher in premarket trading after the discount retailer reported that same-store sales rose 2.6% in February due growth in grocery, electronics and health items. Analysts expected a 1.1% increase according to Thomson Financials. The overall weak sales trend, however, continued into February and shows no sign of improvement.

While discount retailers and wholesale clubs expected to do better, most retail stores were expected to do worse. For example, specialty retailer Limited Brands Inc. (NYSE: LTD) reported that same-store sales fell 9% in February, a smaller drop than the 11% analysts were expecting. While sales fell 10% at Victoria's Secret, they rose 1% at La Senza. Total sales fell 16% and the company expects March to show much the same results.
