Cramer says Under Armour is a technical apparel company and a "stealth" play on technology.
The company continues to innovate and consumers love the brand. That allows it to continue to command premium pricing, according to Cramer.
Under Armour has a market cap of just $8.5 billion, much smaller than Nike's (NKE - Get Report) $60 billion, so Under Armour has a lot of potential to go higher, despite being up 66% in 2013, according to Cramer.With just a small share in the international market, Cramer said the company has a ton of opportunity abroad and that CEO Ken Plank is a very competitive leader. He concluded that the stock has plenty of upside remaining and those who have betted against the company based on valuation have been wrong so far. At the time of publication, Action Alerts PLUS, which Cramer co-manages as a charitable trust, had no positions in stocks mentioned. -- Written by Bret Kenwell in Petoskey, Mich. Follow @BretKenwell
