For many investors, the main point of stock picking is to generate higher returns than the overall market. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term TKD Science and Technology Co.,Ltd. (SHSE:603738) shareholders, since the share price is down 47% in the last three years, falling well short of the market decline of around 15%. Unfortunately the share price momentum is still quite negative, with prices down 11% in thirty days.

Since TKD Science and TechnologyLtd has shed CN¥637m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 three years that the share price fell, TKD Science and TechnologyLtd's earnings per share (EPS) dropped by 19% each year. The 19% average annual share price decline is remarkably close to the EPS decline. So it seems that investor expectations of the company are staying pretty steady, despite the disappointment. It seems like the share price is reflecting the declining earnings per share.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

While the broader market gained around 9.3% in the last year, TKD Science and TechnologyLtd shareholders lost 8.7% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 2% 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. Consider risks, for instance.
