When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. Long term Chemring Group PLC (LON:CHG) shareholders would be well aware of this, since the stock is up 138% in five years.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

View our latest analysis for Chemring Group

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 the last half decade, Chemring Group became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the Chemring Group share price is up 29% in the last three years. During the same period, EPS grew by 3.9% each year. This EPS growth is lower than the 9% average annual increase in the share price over three years. So it's fair to assume the market has a higher opinion of the business than it did three years ago.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Chemring Group, it has a TSR of 161% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that Chemring Group shareholders have received a total shareholder return of 26% over one year. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 21% per year), it would seem that the stock's performance has improved in recent times. 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.
