Long term investing can be life changing when you buy and hold the truly great businesses. While the best companies are hard to find, but they can generate massive returns over long periods. Don't believe it? Then look at the Supply Network Limited (ASX:SNL) share price. It's 666% higher than it was five years ago. If that doesn't get you thinking about long term investing, we don't know what will. It's also good to see the share price up 11% over the last quarter. But this could be related to the strong market, which is up 5.8% in the last three months. We love happy stories like this one. The company should be really proud of that performance!

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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 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, Supply Network managed to grow its earnings per share at 29% a year. This EPS growth is slower than the share price growth of 50% 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. That's not necessarily surprising considering the five-year track record of earnings growth.

We know that Supply Network has improved its bottom line over the last three years, but what does the future have in store? It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Supply Network, it has a TSR of 793% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Supply Network shareholders have received a total shareholder return of 117% over one year. And that does include the dividend. That's better than the annualised return of 55% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
