Jiusheng Electric Co., Ltd. (SZSE:301082) shares have continued their recent momentum with a 51% gain in the last month alone. Looking back a bit further, it's encouraging to see the stock is up 60% in the last year.

Although its price has surged higher, it's still not a stretch to say that Jiusheng Electric's price-to-sales (or "P/S") ratio of 2.4x right now seems quite "middle-of-the-road" compared to the Electrical industry in China, seeing as it matches the P/S ratio of the wider industry. 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.

What Does Jiusheng Electric's Recent Performance Look Like?

For instance, Jiusheng Electric's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The P/S Ratio?

The only time you'd be comfortable seeing a P/S like Jiusheng Electric's is when the company's growth is tracking the industry closely.

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 1.6%. That put a dampener on the good run it was having over the longer-term as its three-year revenue growth is still a noteworthy 8.7% in total. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly satisfied with the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 25% 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 interesting that Jiusheng Electric 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. They may be setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

What Does Jiusheng Electric's P/S Mean For Investors?

Jiusheng Electric's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. 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.

We've established that Jiusheng Electric's average P/S is a bit surprising since its recent three-year growth is lower than the wider industry forecast. Right now we are uncomfortable with the P/S as this revenue performance isn't likely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's hard to accept the current share price as fair value.
