AptarGroup (NYSE:ATR) sheds 12% this week, as yearly returns fall more in line with earnings growth

AptarGroup, Inc. (NYSE:ATR) shareholders have seen the share price descend 13% over the month. On the other hand the share price is higher than it was three years ago. However, it's unlikely many shareholders are elated with the share price gain of 31% over that time, given the rising market.

Although AptarGroup has shed US$1.3b from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

AptarGroup was able to grow its EPS at 19% per year over three years, sending the share price higher. The average annual share price increase of 9% is actually lower than the EPS growth. So it seems investors have become more cautious about the company, over time.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of AptarGroup, it has a TSR of 36% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in AptarGroup had a tough year, with a total loss of 2.1% (including dividends), against a market gain of about 23%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 5%, each year, over five years. 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.
