If you buy and hold a stock for many years, you'd hope to be making a profit. But more than that, you probably want to see it rise more than the market average. Unfortunately for shareholders, while the AptarGroup, Inc. (NYSE:ATR) share price is up 37% in the last five years, that's less than the market return. Some buyers are laughing, though, with an increase of 27% in the last year.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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 half a decade, AptarGroup managed to grow its earnings per share at 6.4% a year. This EPS growth is remarkably close to the 7% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of AptarGroup, it has a TSR of 46% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's good to see that AptarGroup has rewarded shareholders with a total shareholder return of 28% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 8%. 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.
