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 five years of share price growth, Yanchang Petroleum International moved from a loss to profitability. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics may better explain the share price move.
In contrast to the share price, revenue has actually increased by 26% a year in the five year period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

A Different Perspective
Investors in Yanchang Petroleum International had a tough year, with a total loss of 33%, against a market gain of about 5.1%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 12% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality 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.
