You may think that with a price-to-sales (or "P/S") ratio of 0.5x TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT Co., LTD. (SZSE:000826) is definitely a stock worth checking out, seeing as almost half of all the Commercial Services companies in China have P/S ratios greater than 2.6x and even P/S above 5x aren't out of the ordinary. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so limited.

How TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT Has Been Performing

For example, consider that TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT's financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Is There Any Revenue Growth Forecasted For TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT?

The only time you'd be truly comfortable seeing a P/S as depressed as TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT's is when the company's growth is on track to lag the industry decidedly.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 19%. The last three years don't look nice either as the company has shrunk revenue by 36% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 30% shows it's an unpleasant look.

With this information, we are not surprised that TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT is trading at a P/S lower than the industry. Nonetheless, there's no guarantee the P/S has reached a floor yet with revenue going in reverse. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

What Does TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT's P/S Mean For Investors?

It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

It's no surprise that TUS ENVIRONMENTAL SCIENCE AND TECHNOLOGY DEVELOPMENT maintains its low P/S off the back of its sliding revenue over the medium-term. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
