Shentong Technology Group Co., Ltd (SHSE:605228) shareholders that were waiting for something to happen have been dealt a blow with a 34% share price drop in the last month. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 23% in that time.

Although its price has dipped substantially, you could still be forgiven for feeling indifferent about Shentong Technology Group's P/S ratio of 2.1x, since the median price-to-sales (or "P/S") ratio for the Auto Components industry in China is also close to 2x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

How Shentong Technology Group Has Been Performing

Revenue has risen at a steady rate over the last year for Shentong Technology Group, which is generally not a bad outcome. One possibility is that the P/S is moderate because investors think this good revenue growth might only be parallel to the broader industry in the near future. If not, then at least existing shareholders probably aren't too pessimistic about the future direction of the share price.

How Is Shentong Technology Group's Revenue Growth Trending?

Shentong Technology Group's P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

Taking a look back first, we see that the company managed to grow revenues by a handy 7.0% last year. Although, the latest three year period in total hasn't been as good as it didn't manage to provide any growth at all. Therefore, it's fair to say that revenue growth has been inconsistent recently for the company.

This is in contrast to the rest of the industry, which is expected to grow by 25% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it interesting that Shentong Technology Group is trading at a fairly similar P/S compared to the industry. Apparently many investors in the company are less bearish than recent times would indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as a continuation of recent revenue trends is likely to weigh down the shares eventually.

What Does Shentong Technology Group's P/S Mean For Investors?

With its share price dropping off a cliff, the P/S for Shentong Technology Group looks to be in line with the rest of the Auto Components industry. 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.

Our examination of Shentong Technology Group revealed its poor three-year revenue trends aren't resulting in a lower P/S as per our expectations, given they look worse than current industry outlook. When we see weak revenue with slower than industry growth, we suspect the share price is at risk of declining, bringing the P/S back in line with expectations. If recent medium-term revenue trends continue, the probability of a share price decline will become quite substantial, placing shareholders at risk.
