Albemarle Corporation (NYSE:ALB) shareholders should be happy to see the share price up 24% in the last quarter. But that doesn't change the fact that the returns over the last three years have been disappointing. In that time, the share price dropped 61%. So the improvement may be a real relief to some. Perhaps the company has turned over a new leaf.

If the past week is anything to go by, investor sentiment for Albemarle isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over the three years that the share price declined, Albemarle's earnings per share (EPS) dropped significantly, falling to a loss. Due to the loss, it's not easy to use EPS as a reliable guide to the business. But it's safe to say we'd generally expect the share price to be lower as a result!

A Different Perspective

While the broader market gained around 36% in the last year, Albemarle shareholders lost 12% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 11% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Albemarle you should know about.
