Every investor on earth makes bad calls sometimes. But you have a problem if you face massive losses more than once in a while. So spare a thought for the long term shareholders of Autek China Inc. (SZSE:300595); the share price is down a whopping 85% in the last three years. That might cause some serious doubts about the merits of the initial decision to buy the stock, to put it mildly. And the ride hasn't got any smoother in recent times over the last year, with the price 51% lower in that time. The falls have accelerated recently, with the share price down 16% in the last three months. Of course, this share price action may well have been influenced by the 7.2% decline in the broader market, throughout the period. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

If the past week is anything to go by, investor sentiment for Autek China isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

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).

During the unfortunate three years of share price decline, Autek China actually saw its earnings per share (EPS) improve by 6.6% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

With a rather small yield of just 1.4% we doubt that the stock's share price is based on its dividend. We note that, in three years, revenue has actually grown at a 16% annual rate, so that doesn't seem to be a reason to sell shares. It's probably worth investigating Autek China further; while we may be missing something on this analysis, there might also be an opportunity.

A Different Perspective

We regret to report that Autek China shareholders are down 50% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 17%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 0.5% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. It's always interesting to track share price performance over the longer term. But to understand Autek China better, we need to consider many other factors.
