Those holding Zhejiang Yangfan New Materials Co., Ltd. (SZSE:300637) shares would be relieved that the share price has rebounded 38% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. But the gains over the last month weren't enough to make shareholders whole, as the share price is still down 4.6% in the last twelve months.

Following the firm bounce in price, when almost half of the companies in China's Chemicals industry have price-to-sales ratios (or "P/S") below 1.9x, you may consider Zhejiang Yangfan New Materials as a stock probably not worth researching with its 2.5x 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 as high as it is.

How Has Zhejiang Yangfan New Materials Performed Recently?

As an illustration, revenue has deteriorated at Zhejiang Yangfan New Materials over the last year, which is not ideal at all. 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Zhejiang Yangfan New Materials would need to produce impressive growth in excess of the industry.

Retrospectively, the last year delivered a frustrating 14% decrease to the company's top line. Still, the latest three year period has seen an excellent 69% overall rise in revenue, in spite of its unsatisfying short-term performance. Although it's been a bumpy ride, it's still fair to say the revenue growth recently has been more than adequate for the company.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 25% shows it's noticeably less attractive.

In light of this, it's alarming that Zhejiang Yangfan New Materials' P/S sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

The Bottom Line On Zhejiang Yangfan New Materials' P/S

The large bounce in Zhejiang Yangfan New Materials' shares has lifted the company's P/S handsomely. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

The fact that Zhejiang Yangfan New Materials currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these the share price as being reasonable.
