If you love investing in stocks you're bound to buy some losers. Long term Under Armour, Inc. (NYSE:UAA) shareholders know that all too well, since the share price is down considerably over three years. Unfortunately, they have held through a 66% decline in the share price in that time. Even worse, it's down 9.6% in about a month, which isn't fun at all.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over the three years that the share price declined, Under Armour's earnings per share (EPS) dropped significantly, falling to a loss. Extraordinary items contributed to this situation. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.
