There's Reason For Concern Over Wuhan Golden Laser Co., Ltd's (SZSE:300220) Massive 33% Price Jump

Wuhan Golden Laser Co., Ltd (SZSE:300220) shares have continued their recent momentum with a 33% gain in the last month alone. The annual gain comes to 215% following the latest surge, making investors sit up and take notice.

After such a large jump in price, when almost half of the companies in China's Machinery industry have price-to-sales ratios (or "P/S") below 3.3x, you may consider Wuhan Golden Laser as a stock not worth researching with its 10.1x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

What Does Wuhan Golden Laser's P/S Mean For Shareholders?

For instance, Wuhan Golden Laser's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. However, if this isn't the case, investors might get caught out paying too much for the stock.

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

Wuhan Golden Laser's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

Retrospectively, the last year delivered a frustrating 3.8% decrease to the company's top line. The last three years don't look nice either as the company has shrunk revenue by 22% in aggregate. 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 22% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this in mind, we find it worrying that Wuhan Golden Laser's P/S exceeds that of its industry peers. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

What Does Wuhan Golden Laser's P/S Mean For Investors?

The strong share price surge has lead to Wuhan Golden Laser's P/S soaring as well. 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.

Our examination of Wuhan Golden Laser revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
