TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT Co., LTD. (SZSE:000826) shareholders will doubtless be very grateful to see the share price up 34% in the last month. But spare a thought for the long term holders, who have held the stock as it bled value over the last five years. Indeed, the share price is down a whopping 83% in that time. It's true that the recent bounce could signal the company is turning over a new leaf, but we are not so sure. The important question is if the business itself justifies a higher share price in the long term. We really feel for shareholders in this scenario. It's a good reminder of the importance of diversification, and it's worth keeping in mind there's more to life than money, anyway.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Shareholders of unprofitable companies usually expect strong revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

Over half a decade TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT reduced its trailing twelve month revenue by 11% for each year. That puts it in an unattractive cohort, to put it mildly. So it's not that strange that the share price dropped 13% per year in that period. We don't think this is a particularly promising picture. Ironically, that behavior could create an opportunity for the contrarian investor - but only if there are good reasons to predict a brighter future.

A Different Perspective

While the broader market lost about 11% in the twelve months, TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT shareholders did even worse, losing 25%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, longer term shareholders are suffering worse, given the loss of 13% doled out over the last five years. We would want clear information suggesting the company will grow, before taking the view that the share price will stabilize. It's always interesting to track share price performance over the longer term. But to understand TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT better, we need to consider many other factors.
