Oppenheimer analyst Brian Nagel raised his price target for Home Depot (HD) to $205 from $115 and for Lowe's (LOW) to $178 from $100. After reevaluating the underlying trends in the home improvement space, the analyst believes the stocks of both companies remain attractive. Corporate tax reform in the U.S. "implies a step-function higher" in earnings power for Home Depot and Lowe's, and should empower the companies to even more aggressively return capital to shareholders, Nagel contends. He recommends using any pullback in the stocks from the return to normal winter weather as a buying opportunity.
