Generally speaking long term investing is the way to go. But that doesn't mean long term investors can avoid big losses. For example, after five long years the China Display Optoelectronics Technology Holdings Limited (HKG:334) share price is a whole 67% lower. That is extremely sub-optimal, to say the least. We also note that the stock has performed poorly over the last year, with the share price down 43%. The last week also saw the share price slip down another 21%.
With the stock having lost 21% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

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 five years over which the share price declined, China Display Optoelectronics Technology Holdings' earnings per share (EPS) dropped by 31% each year. The share price decline of 20% per year isn't as bad as the EPS decline. So the market may previously have expected a drop, or else it expects the situation will improve.

A Different Perspective
China Display Optoelectronics Technology Holdings shareholders are down 43% for the year, but the market itself is up 2.8%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 11% per year over five years. 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.
