Buying shares in the best businesses can build meaningful wealth for you and your family. And highest quality companies can see their share prices grow by huge amounts. For example, the EMCOR Group, Inc. (NYSE:EME) share price is up a whopping 367% in the last half decade, a handsome return for long term holders. If that doesn't get you thinking about long term investing, we don't know what will. On top of that, the share price is up 53% in about a quarter. The company reported its financial results recently; you can catch up on the latest numbers by reading our company report.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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...' 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.

Over half a decade, EMCOR Group managed to grow its earnings per share at 24% a year. This EPS growth is slower than the share price growth of 36% 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.

It is of course excellent to see how EMCOR Group has grown profits over the years, but the future is more important for shareholders. Take a more thorough look at EMCOR Group's financial health with this free report on its balance sheet.

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 is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for EMCOR Group the TSR over the last 5 years was 377%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's nice to see that EMCOR Group shareholders have received a total shareholder return of 134% over the last year. Of course, that includes the dividend. That's better than the annualised return of 37% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
