This week we saw the Brilliance Technology Co., Ltd. (SZSE:300542) share price climb by 17%. But that doesn't change the fact that the returns over the last year have been less than pleasing. In fact the stock is down 26% in the last year, well below the market return.

The recent uptick of 17% could be a positive sign of things to come, so let's take a look at historical fundamentals.

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).

Unhappily, Brilliance Technology had to report a 60% decline in EPS over the last year. This fall in the EPS is significantly worse than the 26% the share price fall. So the market may not be too worried about the EPS figure, at the moment -- or it may have expected earnings to drop faster. With a P/E ratio of 123.47, it's fair to say the market sees an EPS rebound on the cards.

A Different Perspective

We regret to report that Brilliance Technology shareholders are down 26% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 20%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 4% per year over half a decade. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
