Yongyue Science&Technology Co.,Ltd (SHSE:603879) shares have had a really impressive month, gaining 29% after a shaky period beforehand. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 49% over that time.

Following the firm bounce in price, given close to half the companies operating in China's Chemicals industry have price-to-sales ratios (or "P/S") below 2.3x, you may consider Yongyue Science&TechnologyLtd as a stock to potentially avoid with its 3.4x P/S ratio. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

What Does Yongyue Science&TechnologyLtd's Recent Performance Look Like?

The revenue growth achieved at Yongyue Science&TechnologyLtd over the last year would be more than acceptable for most companies. It might be that many expect the respectable revenue performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The High P/S Ratio?

Yongyue Science&TechnologyLtd's P/S ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the industry.

If we review the last year of revenue growth, the company posted a worthy increase of 15%. Still, lamentably revenue has fallen 22% in aggregate from three years ago, which is disappointing. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 24% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this information, we find it concerning that Yongyue Science&TechnologyLtd 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. 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.

The Final Word

Yongyue Science&TechnologyLtd shares have taken a big step in a northerly direction, but its P/S is elevated as a result. 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 Yongyue Science&TechnologyLtd 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. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
