Nike’s long-term prospects remain compelling, but the sales trends in the next several quarters will probably remain sluggish given a combination of spotty consumer demand, lulls in product innovation and some modest incursions from competitors in certain categories, Oppenheimer analysts say in a research note. “While NKE is by no means broken, we believe that the company and its brand are transitioning, near-term,” the analysts say. They’re downgrading the stock to perform from outperform, and lowering the target price to $110 from $150. The analysts add that they’re “hard-pressed to envision the still-premium valuation of NKE climbing higher, until clearer signals of sustained, improved fundamental expansion emerge.” Nike slides 4% to $101.88.
