Despite an already strong run, Zhejiang FORE Intelligent Technology Co.,Ltd (SZSE:301368) shares have been powering on, with a gain of 32% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 64% in the last year.

Since its price has surged higher, given around half the companies in China's Machinery industry have price-to-sales ratios (or "P/S") below 3.6x, you may consider Zhejiang FORE Intelligent TechnologyLtd as a stock to avoid entirely with its 21.6x 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.

How Zhejiang FORE Intelligent TechnologyLtd Has Been Performing

The revenue growth achieved at Zhejiang FORE Intelligent TechnologyLtd over the last year would be more than acceptable for most companies. One possibility is that the P/S ratio is high because investors think this respectable revenue growth will be 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.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Zhejiang FORE Intelligent TechnologyLtd would need to produce outstanding growth that's well in excess of the industry.

Taking a look back first, we see that the company grew revenue by an impressive 22% last year. However, this wasn't enough as the latest three year period has seen the company endure a nasty 15% drop in revenue in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 23% shows it's an unpleasant look.

With this in mind, we find it worrying that Zhejiang FORE Intelligent TechnologyLtd's P/S exceeds that of its industry peers. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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 We Can Learn From Zhejiang FORE Intelligent TechnologyLtd's P/S?

Shares in Zhejiang FORE Intelligent TechnologyLtd have seen a strong upwards swing lately, which has really helped boost its P/S figure. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Zhejiang FORE Intelligent TechnologyLtd currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. 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.
