Huaneng Power International's (HKG:902) investors will be pleased with their respectable 35% return over the last five years

When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. For example, long term Huaneng Power International, Inc. (HKG:902) shareholders have enjoyed a 14% share price rise over the last half decade, well in excess of the market decline of around 5.8% (not including dividends).

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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. As it happens, Huaneng Power International's TSR for the last 5 years was 35%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 31% in the last year, Huaneng Power International shareholders lost 0.7% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 6% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. It's always interesting to track share price performance over the longer term. But to understand Huaneng Power International better, we need to consider many other factors.
