The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. For example, the Canadian Natural Resources Limited (TSE:CNQ) share price has soared 120% in the last half decade. Most would be very happy with that. Better yet, the share price has risen 4.9% in the last week.

Since the stock has added CA$4.5b to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, Canadian Natural Resources achieved compound earnings per share (EPS) growth of 16% per year. So the EPS growth rate is rather close to the annualized share price gain of 17% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

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 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Canadian Natural Resources the TSR over the last 5 years was 194%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Canadian Natural Resources shareholders gained a total return of 6.6% during the year. But that return falls short of the market. On the bright side, the longer term returns (running at about 24% a year, over half a decade) look better. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. It is all well and good that insiders have been buying shares, but we suggest you check here to see what price insiders were buying at.
