The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. Long term Amphenol Corporation (NYSE:APH) shareholders would be well aware of this, since the stock is up 173% in five years. It's also good to see the share price up 21% over the last quarter. But this could be related to the strong market, which is up 12% in the last three months.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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.

During five years of share price growth, Amphenol achieved compound earnings per share (EPS) growth of 13% per year. This EPS growth is lower than the 22% 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?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Amphenol, it has a TSR of 186% 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

We're pleased to report that Amphenol shareholders have received a total shareholder return of 56% over one year. And that does include the dividend. That gain is better than the annual TSR over five years, which is 23%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. It's always interesting to track share price performance over the longer term. But to understand Amphenol better, we need to consider many other factors.
