Shenyang Machine Tool Co., Ltd. (SZSE:000410) shareholders are no doubt pleased to see that the share price has bounced 30% in the last month, although it is still struggling to make up recently lost ground. Taking a wider view, although not as strong as the last month, the full year gain of 19% is also fairly reasonable.

Following the firm bounce in price, given around half the companies in China's Machinery industry have price-to-sales ratios (or "P/S") below 2.7x, you may consider Shenyang Machine Tool as a stock to avoid entirely with its 9.7x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

How Has Shenyang Machine Tool Performed Recently?

For instance, Shenyang Machine Tool's receding revenue in recent times would have to be some food for thought. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

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 Shenyang Machine Tool's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 8.4% decrease to the company's top line. However, a few very strong years before that means that it was still able to grow revenue by an impressive 42% in total over the last three years. So we can start by confirming that the company has generally done a very good job of growing revenue over that time, even though it had some hiccups along the way.

Comparing that to the industry, which is predicted to deliver 27% 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 Shenyang Machine Tool 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

Shares in Shenyang Machine Tool have seen a strong upwards swing lately, which has really helped boost its P/S figure. 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 Shenyang Machine Tool 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. 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.
