ASM International (AMS:ASM) shareholders have earned a 41% CAGR over the last five years

ASM International NV (AMS:ASM) shareholders might be concerned after seeing the share price drop 21% in the last quarter. But that doesn't undermine the fantastic longer term performance (measured over five years). To be precise, the stock price is 429% higher than it was five years ago, a wonderful performance by any measure. So it might be that some shareholders are taking profits after good performance. Of course what matters most is whether the business can improve itself sustainably, thus justifying a higher price.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, ASM International managed to grow its earnings per share at 16% a year. This EPS growth is lower than the 40% average annual increase in the share price. 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.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for ASM International the TSR over the last 5 years was 455%, 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

We regret to report that ASM International shareholders are down 21% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 3.7%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Longer term investors wouldn't be so upset, since they would have made 41%, 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. It's always interesting to track share price performance over the longer term. But to understand ASM International better, we need to consider many other factors.
