There's Reason For Concern Over Jiangsu Wuyang Automation Control Technology Co., Ltd.'s (SZSE:300420) Massive 37% Price Jump

Despite an already strong run, Jiangsu Wuyang Automation Control Technology Co., Ltd. (SZSE:300420) shares have been powering on, with a gain of 37% in the last thirty days. Taking a wider view, although not as strong as the last month, the full year gain of 24% is also fairly reasonable.

Following the firm bounce 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 Jiangsu Wuyang Automation Control Technology as a stock probably not worth researching with its 4x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

What Does Jiangsu Wuyang Automation Control Technology's P/S Mean For Shareholders?

For example, consider that Jiangsu Wuyang Automation Control Technology's financial performance has been poor lately as its revenue has been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

How Is Jiangsu Wuyang Automation Control Technology's Revenue Growth Trending?

The only time you'd be truly comfortable seeing a P/S as high as Jiangsu Wuyang Automation Control Technology's is when the company's growth is on track to outshine 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 26%. The last three years don't look nice either as the company has shrunk revenue by 34% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 24% shows it's an unpleasant look.

With this information, we find it concerning that Jiangsu Wuyang Automation Control Technology is trading at a P/S higher than the industry. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Final Word

Jiangsu Wuyang Automation Control Technology shares have taken a big step in a northerly direction, but its P/S is elevated as a result. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

We've established that Jiangsu Wuyang Automation Control Technology currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. 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.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Jiangsu Wuyang Automation Control Technology, and understanding should be part of your investment process.
