"We believe the market fairly reflects the fact that HD continues to outperform on the sales and EBIT earnings before interest and taxes lines and the greater likelihood of downside risk at LOW," Jefferies said, adding later: "Expecting HD to outperform LOW. Based on our checks, we believe Home Depot's 2Q results will continue to outperform Lowe's, despite both likely slowing sequentially against more challenging comparisons and a pull forward of demand in 1Q." That said, as reflected by the firm's hold ratings on both stocks, Jefferies thinks the overall market environment is a headwind. "Our checks on home improvement retail throughout the quarter indicate softer comp store sales, particularly in June, driven by: 1) the weather-related pull forward of demand in 1Q; 2) more challenging comparisons; 3) extreme temperatures/drought that reduced demand for lawn & garden products in some parts of the country; and 4) continued sluggishness in big ticket items," Jefferies said. "Vendors sound a bit more cautious on DIY do-it-yourself . Building materials vendors have been putting up good numbers this earnings season, but a lot of this has been attributable to improvements in new home construction. Many of these supplier comments have been more cautious around the DIY business." The firm is in-line with consensus, expecting earnings of 97 cents a shares from Home Deport in the quarter with same-store sales seen up 2%, and it has a $48 price target on the stock, implying potential downside of more than 9% from current levels.
