If you love investing in stocks you're bound to buy some losers. Long term Joinn Laboratories(China)Co.,Ltd. (SHSE:603127) shareholders know that all too well, since the share price is down considerably over three years. Unfortunately, they have held through a 71% decline in the share price in that time. The more recent news is of little comfort, with the share price down 29% in a year. Unfortunately the share price momentum is still quite negative, with prices down 17% in thirty days. We do note, however, that the broader market is down 11% in that period, and this may have weighed on the share price.

After losing 6.4% 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 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.

Over the three years that the share price declined, Joinn Laboratories(China)Co.Ltd's earnings per share (EPS) dropped significantly, falling to a loss. Extraordinary items contributed to this situation. Due to the loss, it's not easy to use EPS as a reliable guide to the business.

A Different Perspective

Joinn Laboratories(China)Co.Ltd shareholders are down 29% for the year (even including dividends), but the market itself is up 6.5%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% 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.
