It might be of some concern to shareholders to see the Camtek Ltd. (NASDAQ:CAMT) share price down 20% in the last month. But over five years returns have been remarkably great. To be precise, the stock price is 675% higher than it was five years ago, a wonderful performance by any measure. Arguably, the recent fall is to be expected after such a strong rise. Of course what matters most is whether the business can improve itself sustainably, thus justifying a higher price. It really delights us to see such great share price performance for investors.

Since the long term performance has been good but there's been a recent pullback of 10%, let's check if the fundamentals match the share price.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, Camtek managed to grow its earnings per share at 36% a year. This EPS growth is lower than the 51% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Camtek, it has a TSR of 688% 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

While the broader market gained around 16% in the last year, Camtek shareholders lost 11% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 51%, 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider risks, for instance.
