Guangzhou Pearl River Piano GroupLtd (SZSE:002678 shareholders incur further losses as stock declines 8.3% this week, taking five-year losses to 48%

For many, the main point of investing is to generate higher returns than the overall market. But even the best stock picker will only win with some selections. So we wouldn't blame long term Guangzhou Pearl River Piano Group Co.,Ltd (SZSE:002678) shareholders for doubting their decision to hold, with the stock down 49% over a half decade. And it's not just long term holders hurting, because the stock is down 35% in the last year. Unfortunately the share price momentum is still quite negative, with prices down 14% in thirty days.

Since Guangzhou Pearl River Piano GroupLtd has shed CN¥476m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

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).

Over five years Guangzhou Pearl River Piano GroupLtd's earnings per share dropped significantly, falling to a loss, with the share price also lower. At present it's hard to make valid comparisons between EPS and the share price. But we would generally expect a lower price, given the situation.

A Different Perspective

We regret to report that Guangzhou Pearl River Piano GroupLtd shareholders are down 35% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 9.6%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 8% 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. Consider for instance, the ever-present spectre of investment risk.
