				Spieth last year signed a 10-year agreement to wear the No. 2 
				U.S. sportswear maker's golf shoes and other clothes, and his 
				collapse in Sunday's final round appeared to be partly behind 
				the drop in the company's shares.
 Also hurting the stock, Morgan Stanley said in a note that Under 
				Armour, a leader in "athleisure," appears to be losing market 
				share for the first time in three years.
 
 But Spieth's loss is unlikely to dent Under Armour's growth 
				momentum and the stock's selloff may reflect the sports 
				preferences of many on Wall Street, said BB&T analyst Corrina 
				Freedman.
 
 Under Armour has signed endorsement deals with a number of 
				high-flying professional athletes, which have helped elevate its 
				profile and boost sales.
 
 Impressive performances by two other major Under Armour 
				endorsers - National Basketball Association point guard Stephen 
				Curry and National Football League quarterback Cam Newton - have 
				not sparked major rallies in the company's stock.
 
 Under Armour also sponsors English soccer club Tottenham 
				Hotspur, which is second in the Premier League.
 
 "More Wall Street traders watch golf than watch basketball, it 
				would appear," Freedman said.
 
 "Steph Curry is having a phenomenal season, but the stock 
				doesn't move on significant advances by Steph Curry. And Cam 
				Newton in the Super Bowl didn't have much of an impact either."
 
 In a research note, Morgan Stanley analyst Jay Sole wrote that 
				he believes that Under Armour's core U.S. wholesale apparel 
				growth has slowed.
 
 Under Armour has been quick to cash in on the new trend of "athleisure," 
				a mash-up of athletic and casual clothing growing popular even 
				in formal settings like offices, which has helped it maintain a 
				revenue growth momentum of more than 20 percent for 23 straight 
				quarters.
 
 Wall Street expects Under Armour's revenues for the March 
				quarter to jump 29 percent. The company is due to report its 
				results on April 21.
 
 The company's stock was down 5.77 percent at $41.03 in late 
				Monday afternoon trading on the New York Stock Exchange.
