North Copper (SZSE:000737) shareholders notch a 24% CAGR over 5 years, yet earnings have been shrinking

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 when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of North Copper Co., Ltd. (SZSE:000737) stock is up an impressive 193% over the last five years. It's even up 12% in the last week.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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 way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, North Copper actually saw its EPS drop 14% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

We doubt the modest 1.1% dividend yield is attracting many buyers to the stock. On the other hand, North Copper's revenue is growing nicely, at a compound rate of 29% over the last five years. It's quite possible that management are prioritizing revenue growth over EPS growth at the moment.

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?

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, North Copper's TSR for the last 5 years was 196%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that North Copper shareholders have received a total shareholder return of 51% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 24% 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.
