It is doubtless a positive to see that the Nanjing Sample Technology Company Limited (HKG:1708) share price has gained some 122% in the last three months. But that doesn't help the fact that the three year return is less impressive. In fact, the share price is down 50% in the last three years, falling well short of the market return.
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 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).
Nanjing Sample Technology saw its EPS decline at a compound rate of 50% per year, over the last three years. In comparison the 20% compound annual share price decline isn't as bad as the EPS drop-off. So the market may not be too worried about the EPS figure, at the moment -- or it may have previously priced some of the drop in. With a P/E ratio of 128.37, it's fair to say the market sees a brighter future for the business.

A Different Perspective
While the broader market gained around 24% in the last year, Nanjing Sample Technology shareholders lost 5.0%. 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. Longer term investors wouldn't be so upset, since they would have made 1.4%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
