When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of Amphenol Corporation (NYSE:APH) stock is up an impressive 127% over the last five years. Also pleasing for shareholders was the 22% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 15% in 90 days).

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, Amphenol managed to grow its earnings per share at 9.9% a year. This EPS growth is slower than the share price growth of 18% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Amphenol the TSR over the last 5 years was 139%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Amphenol has rewarded shareholders with a total shareholder return of 33% in the last twelve months. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 19% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper.
