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, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Dollarama Inc. (TSE:DOL) share price has soared 171% in the last half decade. Most would be very happy with that. In the last week the share price is up 4.1%.

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 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, Dollarama achieved compound earnings per share (EPS) growth of 22% per year. This EPS growth is remarkably close to the 22% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Rather, the share price has approximately tracked EPS growth.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. We note that for Dollarama the TSR over the last 5 years was 177%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Dollarama shareholders have received a total shareholder return of 27% over one year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 23%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
