Yanchang Petroleum International (HKG:346) earnings and shareholder returns have been trending downwards for the last three years, but the stock spikes 12% this past week

If you are building a properly diversified stock portfolio, the chances are some of your picks will perform badly. But the long term shareholders of Yanchang Petroleum International Limited (HKG:346) have had an unfortunate run in the last three years. Regrettably, they have had to cope with a 66% drop in the share price over that period.

While the last three years has been tough for Yanchang Petroleum International shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative 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 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 the three years that the share price fell, Yanchang Petroleum International's earnings per share (EPS) dropped by 50% each year. This fall in the EPS is worse than the 30% compound annual share price fall. So, despite the prior disappointment, shareholders must have some confidence the situation will improve, longer term.

A Different Perspective

It's nice to see that Yanchang Petroleum International shareholders have received a total shareholder return of 58% over the last year. Notably the five-year annualised TSR loss of 9% per year compares very unfavourably with the recent share price performance. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. 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.
