Is the Wal-Mart Weakness Company Specific or Industry-Wide?

Wal-Mart Expects Sales at Bottom Of June Forecast

• Summary: Wal-Mart said Saturday that it estimates June year over year same-store sales growth of only 1.2%, at the bottom of its prior prediction of 1-3%. Analysts differed on whether the tepid growth was company-specific or industry-wide. The shortfall may have been caused, or exacerbated by, Wal-Mart's remodelling of 1,800 stores over the next year and a half, involving inventory cuts, emphasis on higher value non-grocery sales and a reduction in labor hours to align workers with peak shopping hours. The consensus estimates for industry-wide June same store sales is currently 3.3%. However, JP Morg an said that Wal-Mart's numbers suggest that other discount retailers will also post poor June same store sales results. Most retailers will announce June same-store sales on Thursday.
• Comment on related stocks/ETFs: Other discount retails at risk -- if the Wal-Mart (WMT) shortfall is not company-specific -- include Dollar General (DG), Family Dollar Stores (FDO) and Dollar Tree Stores (DLTR). Target (TGT) continues to take share from Wal-Mart; its most recent guidance for June same-store sales is the "upper half" of the 3-5% range.
