Stock pickers are generally looking for stocks that will outperform the broader market. And in our experience, buying the right stocks can give your wealth a significant boost. For example, the Hainan Development HoldingsNanhai Co., Ltd. (SZSE:002163) share price is up 77% in the last 5 years, clearly besting the market return of around 14% (ignoring dividends).

Since it's been a strong week for Hainan Development HoldingsNanhai shareholders, let's have a look at trend of the longer term fundamentals.

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 five years of share price growth, Hainan Development HoldingsNanhai actually saw its EPS drop 36% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. 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.

It is not great to see that revenue has dropped by 2.8% per year over five years. So it seems one might have to take closer look at earnings and revenue trends to see how they might influence the share price.

A Different Perspective

While the broader market gained around 5.2% in the last year, Hainan Development HoldingsNanhai shareholders lost 13%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 12%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
