When close to half the companies in the Electrical industry in China have price-to-sales ratios (or "P/S") below 2.4x, you may consider Roshow Technology Co., Ltd. (SZSE:002617) as a stock to potentially avoid with its 3.9x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Has Roshow Technology Performed Recently?

For instance, Roshow 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. However, if this isn't the case, investors might get caught out paying too much for the stock.

How Is Roshow Technology's Revenue Growth Trending?

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

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 18%. Regardless, revenue has managed to lift by a handy 13% in aggregate from three years ago, thanks to the earlier period of growth. Although it's been a bumpy ride, it's still fair to say the revenue growth recently has been mostly respectable for the company.

Comparing that to the industry, which is predicted to deliver 30% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

With this information, we find it concerning that Roshow Technology is trading at a P/S higher than the industry. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

The Key Takeaway

While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

Our examination of Roshow Technology revealed its poor three-year revenue trends aren't detracting from the P/S as much as we though, given they look worse than current industry expectations. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. Unless there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.

Many other vital risk factors can be found on the company's balance sheet. Our free balance sheet analysis for Roshow Technology with six simple checks will allow you to discover any risks that could be an issue.

Of course, profitable companies with a history of great earnings growth are generally safer bets. So you may wish to see this free collection of other companies that have reasonable P/E ratios and have grown earnings strongly.
