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 on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of NZME Limited (NZSE:NZM) stock is up an impressive 149% over the last five years.

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

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

During five years of share price growth, NZME achieved compound earnings per share (EPS) growth of 6.8% per year. This EPS growth is slower than the share price growth of 20% 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. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of NZME, it has a TSR of 259% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that NZME shareholders have received a total shareholder return of 30% over the last year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 29% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
