Jim Cramer often talks about Under Armour as a stealth tech stock.
"CEO Kevin Plank devotes a huge amount of time on his quarterly conference calls explaining the company's latest scientific breakthroughs," Cramer said.
But at the end of the day, no matter how cutting edge the technology behind the clothing may be, Under Armour is seller of athletic apparel.
And this week, the company took another step forward in its attempts to surpass Nike as the biggest athletic apparel maker on the planet. Under Armour opened its largest store to date in New York City.
"It took us 18 years to get to this point but you don't get to New York City in year one," said Plank during an interview on "Mad Money."
