TheStreet's founder and Action Alerts PLUS Portfolio Manager Jim Cramer said Under Armour (UAA - Get Report) needs to refocus.

The company reported lower than expected guidance on Tuesday. 

"While our international business continues to deliver against our ambition of building a global brand, operational challenges and lower demand in North America resulted in third quarter revenue that was below our expectations," said Under Armour Chairman and CEO Kevin Plank. "Based on these issues in our largest market, we believe it is prudent to reduce our sales and earnings outlook for the remainder of 2017."
