Customers viewed more than 1.5 billion pages on Walmart.com in the five days through yesterday, a period the retailer has dubbed “The New Black Friday.” Mobile devices accounted for about 70 percent of traffic, the Bentonville, Arkansas-based retailer said in a statement, without disclosing sales figures.

Wal-Mart is spreading out its promotions to lure shoppers during a holiday season that promises to hold a number of challenges. While analysts have predicted retail sales will increase in the final two months of the year, many of those purchases are expected to shift online or be won with discounts that threaten retailers’ profitability.

Wal-Mart shares rose 0.2 percent to $86.39 as of 10:33 a.m. in New York. The stock was up 9.6 percent this year through Monday.
