Tatwah Smartech Co.,Ltd.'s (SZSE:002512) price-to-sales (or "P/S") ratio of 2.3x might make it look like a buy right now compared to the Electronic industry in China, where around half of the companies have P/S ratios above 3.5x and even P/S above 7x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Tatwah SmartechLtd's P/S Mean For Shareholders?

For instance, Tatwah SmartechLtd's receding revenue in recent times would have to be some food for thought. 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. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Is There Any Revenue Growth Forecasted For Tatwah SmartechLtd?

The only time you'd be truly comfortable seeing a P/S as low as Tatwah SmartechLtd's is when the company's growth is on track to lag the industry.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 19%. As a result, revenue from three years ago have also fallen 32% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 25% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we understand why Tatwah SmartechLtd's P/S is lower than most of its industry peers. However, we think shrinking revenues are unlikely to lead to a stable P/S over the longer term, which could set up shareholders for future disappointment. Even just maintaining these prices could be difficult to achieve as recent revenue trends are already weighing down the shares.

The Bottom Line On Tatwah SmartechLtd's P/S

We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Tatwah SmartechLtd confirms that the company's shrinking revenue over the past medium-term is a key factor in its low price-to-sales ratio, given the industry is projected to grow. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. Given the current circumstances, it seems unlikely that the share price will experience any significant movement in either direction in the near future if recent medium-term revenue trends persist.
