ASM International (AMS:ASM) shareholders have earned a 28% CAGR over the last five years

ASM International NV (AMS:ASM) shareholders might be concerned after seeing the share price drop 20% in the last month. But that doesn't change the fact that the returns over the last five years have been very strong. In fact, the share price is 228% higher today. To some, the recent pullback wouldn't be surprising after such a fast rise. Only time will tell if there is still too much optimism currently reflected in the share price.

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

Over half a decade, ASM International managed to grow its earnings per share at 12% a year. This EPS growth is slower than the share price growth of 27% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. We note that for ASM International the TSR over the last 5 years was 239%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

ASM International shareholders are down 25% for the year (even including dividends), but the market itself is up 4.1%. 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 28%, 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.
