The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Casella Waste Systems, Inc. (NASDAQ:CWST) share price has soared 141% in the last half decade. Most would be very happy with that. And in the last month, the share price has gained 11%.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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).

During five years of share price growth, Casella Waste Systems actually saw its EPS drop 11% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

In contrast revenue growth of 15% per year is probably viewed as evidence that Casella Waste Systems is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

It's nice to see that Casella Waste Systems shareholders have received a total shareholder return of 41% over the last year. That gain is better than the annual TSR over five years, which is 19%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
