You may think that with a price-to-sales (or "P/S") ratio of 7.9x Datang Telecom Technology Co., Ltd. (SHSE:600198) is a stock to avoid completely, seeing as almost half of all the Communications companies in China have P/S ratios under 4.8x and even P/S lower than 2x aren't out of the ordinary. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does Datang Telecom Technology's P/S Mean For Shareholders?

For instance, Datang Telecom Technology's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Revenue Growth Metrics Telling Us About The High P/S?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like Datang Telecom Technology's to be considered reasonable.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 13%. The last three years don't look nice either as the company has shrunk revenue by 23% in aggregate. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 43% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this information, we find it concerning that Datang Telecom Technology is trading at a P/S higher than the industry. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Bottom Line On Datang Telecom Technology's P/S

Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Datang Telecom Technology revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
