The Jiusheng Electric Co., Ltd. (SZSE:301082) share price has softened a substantial 25% over the previous 30 days, handing back much of the gains the stock has made lately. The recent drop has obliterated the annual return, with the share price now down 2.7% over that longer period.

In spite of the heavy fall in price, given about half the companies operating in China's Electrical industry have price-to-sales ratios (or "P/S") above 2.2x, you may still consider Jiusheng Electric as an attractive investment with its 1.5x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

How Has Jiusheng Electric Performed Recently?

For example, consider that Jiusheng Electric's financial performance has been poor lately as its revenue has been in decline. It might be that many expect the disappointing revenue performance to continue or accelerate, which has repressed the P/S. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

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

In order to justify its P/S ratio, Jiusheng Electric would need to produce sluggish growth that's trailing the industry.

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 the recent medium-term revenue trends against the industry's one-year growth forecast of 25% shows it's noticeably less attractive.

With this in consideration, it's easy to understand why Jiusheng Electric's P/S falls short of the mark set by its industry peers. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

The southerly movements of Jiusheng Electric's shares means its P/S is now sitting at a pretty low level. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

In line with expectations, Jiusheng Electric maintains its low P/S on the weakness of its recent three-year growth being lower than the wider industry forecast. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
