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 the bright side, you can make far more than 100% on a really good stock. For instance, the price of W.W. Grainger, Inc. (NYSE:GWW) stock is up an impressive 221% over the last five years.

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

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. 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, W.W. Grainger managed to grow its earnings per share at 23% a year. This EPS growth is reasonably close to the 26% average annual increase in the share price. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

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. In the case of W.W. Grainger, it has a TSR of 240% 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 W.W. Grainger shareholders have received a total shareholder return of 16% over one year. And that does include the dividend. Having said that, the five-year TSR of 28% a year, is even better. The pessimistic view would be that be that the stock has its best days behind it, but on the other hand the price might simply be moderating while the business itself continues to execute. 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.W. Grainger that you should be aware of before investing here.
