NanJi E-Commerce Co., LTD (SZSE:002127) shareholders should be happy to see the share price up 27% in the last month. But that doesn't change the fact that the returns over the last half decade have been disappointing. Indeed, the share price is down 71% in the period. Some might say the recent bounce is to be expected after such a bad drop. We'd err towards caution given the long term under-performance.

While the last five years has been tough for NanJi E-Commerce shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

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. 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).

NanJi E-Commerce became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics may better explain the share price move.

Arguably, the revenue drop of 7.5% a year for half a decade suggests that the company can't grow in the long term. That could explain the weak share price.

A Different Perspective

NanJi E-Commerce shareholders are down 5.3% for the year (even including dividends), but the market itself is up 3.3%. 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 11% 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. It's always interesting to track share price performance over the longer term. But to understand NanJi E-Commerce better, we need to consider many other factors. Even so, be aware that NanJi E-Commerce is showing 2 warning signs in our investment analysis , and 1 of those is potentially serious...
