Wells Fargo analyst Tom Nikic upgraded Under Armour (UAA) to Market Perform from Underperform and raised his price target for the shares to $23 from $22. The stock closed yesterday up 13c to $23.14. After two-plus years of "choppy operating performance," the worst is now over for Under Armour, Nikic proclaims in a research note to investors. "Simply put, the bear case appears to have run out of steam," adds the analyst. Further, he believes the upcoming analyst day on December 12 is more likely to be a positive catalyst than a negative one. Management will lay out bullish long-term sales and margin targets, Nikic predicts. As such, the analyst no longer sees a "negative skew" to the shares and views the near-term setup as favorable.
