On CAPS, 92% of the 2,828 members who have rated Under Armour believe the stock will outperform the S&P 500 going forward. These bulls include All-Stars Chemdawg and streeter123, both of whom are ranked in the top 20% of our community.

Just last week , Chemdawg wrote that Under Armour shares were worth paying up for:

[N]ot crazy about the valuation here, but I love the product line. ... It has a strong brand and it can hold up over longer periods of time. It sells well even when selling for full price.

Over the next five years, in fact, Under Armour is expected to grow its bottom line at a brisk rate of 23% annually. That's much faster than other active-apparel plays like Nike (11%), Columbia (14%), and VF (NYSE: VFC) (10%).

CAPS All-Star streeter123 offers a balanced take on Under Armour:

Currently, I think the stock is a bit overheated, even with the recent pullback, but I'm not selling. Here's what I like:
- Their stuff is very high quality. The sort-of downside to this as an investor is it lasts for a long time, so people might not buy as much of it. But I think the "halo effect" works here, at least with me. ...

- There is lots of opportunity to move Charged Cotton into more categories, like polo shirts. ... They're always expanding.

- UA has a strong brand name. ... And strong brands are usually better at passing through higher prices, which is coming into play now.

- Kevin Plank is extremely ambitious. ... [I]t's always been clear -- he said in the past that he will never sell the company, and will go down fighting if necessary.

What I don't like:
- Inventory issues. They need to fix this soon. Hopefully their statements about meeting potential demand for new products are accurate.

- Free cash flow. Where is it?
