PetroChina's (HKG:857) investors will be pleased with their massive 366% return over the last five years

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, if you buy shares in a high quality company at the right price, you can gain well over 100%. Long term PetroChina Company Limited (HKG:857) shareholders would be well aware of this, since the stock is up 213% in five years.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the last half decade, PetroChina became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the PetroChina share price is up 120% in the last three years. Meanwhile, EPS is up 9.8% per year. This EPS growth is lower than the 30% average annual increase in the share price over three years. So it's fair to assume the market has a higher opinion of the business than it did three years ago.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for PetroChina the TSR over the last 5 years was 366%, 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

PetroChina provided a TSR of 20% over the last twelve months. But that was short of the market average. If we look back over five years, the returns are even better, coming in at 36% per year for five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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. Take risks, for example - PetroChina has 2 warning signs (and 1 which can't be ignored) we think you should know about.

Of course PetroChina may not be the best stock to buy. So you may wish to see this free collection of growth stocks.
