In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term Glarun Technology Co.,Ltd (SHSE:600562) shareholders have had that experience, with the share price dropping 29% in three years, versus a market decline of about 12%.

After losing 5.6% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Although the share price is down over three years, Glarun TechnologyLtd actually managed to grow EPS by 9.8% per year in that time. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The modest 0.9% dividend yield is unlikely to be guiding the market view of the stock. Arguably the revenue decline of 7.4% per year has people thinking Glarun TechnologyLtd is shrinking. After all, if revenue keeps shrinking, it may be difficult to find earnings growth in the future.

A Different Perspective

Although it hurts that Glarun TechnologyLtd returned a loss of 2.1% in the last twelve months, the broader market was actually worse, returning a loss of 5.8%. Of course, the long term returns are far more important and the good news is that over five years, the stock has returned 2% for each year. It could be that the business is just facing some short term problems, but shareholders should keep a close eye on the fundamentals. 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.
