Oppenheimer says that lululemon's sales momentum is accelerating, after the company reported that its comp sales had jumped 11% in Q2. After the company's Q2 gross margin came in significantly below its guidance, Oppenheimer says the miss was primarily caused by transient issues, primarily higher than expected product costs and currency fluctuations. The firm continues to identify the company as one of its favorite growth ideas in retail, and it predicts that the company's EPS will reach a positive turning point in 2016. It keeps a $75 price target and Outperform rating on the name.
