We're definitely into long term investing, but some companies are simply bad investments over any time frame. We really hate to see fellow investors lose their hard-earned money. Imagine if you held China Fortune Land Development Co., Ltd. (SHSE:600340) for half a decade as the share price tanked 88%. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

Since China Fortune Land Development has shed CN¥623m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During five years of share price growth, China Fortune Land Development moved from a loss to profitability. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

Arguably, the revenue drop of 19% a year for half a decade suggests that the company can't grow in the long term. This has probably encouraged some shareholders to sell down the stock.

A Different Perspective

While the broader market gained around 0.2% in the last year, China Fortune Land Development shareholders lost 17%. 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. However, the loss over the last year isn't as bad as the 13% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. 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.
