Shenzhen Gongjin Electronics Co., Ltd. (SHSE:603118) shareholders would be excited to see that the share price has had a great month, posting a 30% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 36% in the last twelve months.

In spite of the firm bounce in price, Shenzhen Gongjin Electronics' price-to-sales (or "P/S") ratio of 0.7x might still make it look like a strong buy right now compared to the wider Communications industry in China, where around half of the companies have P/S ratios above 3.8x and even P/S above 7x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/S.

How Shenzhen Gongjin Electronics Has Been Performing

As an illustration, revenue has deteriorated at Shenzhen Gongjin Electronics over the last year, which is not ideal at all. One possibility is that the P/S is low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. Those who are bullish on Shenzhen Gongjin Electronics will be hoping that this isn't the case so that they can pick up the stock at a lower valuation.

Do Revenue Forecasts Match The Low P/S Ratio?

Shenzhen Gongjin Electronics' P/S ratio would be typical for a company that's expected to deliver very poor growth or even falling revenue, and importantly, perform much worse than the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 19%. As a result, revenue from three years ago have also fallen 18% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

In contrast to the company, the rest of the industry is expected to grow by 40% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this information, we are not surprised that Shenzhen Gongjin Electronics is trading at a P/S lower than the industry. However, we think shrinking revenues are unlikely to lead to a stable P/S over the longer term, which could set up shareholders for future disappointment. Even just maintaining these prices could be difficult to achieve as recent revenue trends are already weighing down the shares.

The Bottom Line On Shenzhen Gongjin Electronics' P/S

Shenzhen Gongjin Electronics' recent share price jump still sees fails to bring its P/S alongside the industry median. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of Shenzhen Gongjin Electronics revealed its shrinking revenue over the medium-term is contributing to its low P/S, given the industry is set to grow. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. If recent medium-term revenue trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
