Malion New Materials Co., Ltd. (SZSE:300586) shareholders won't be pleased to see that the share price has had a very rough month, dropping 25% and undoing the prior period's positive performance. Longer-term shareholders will rue the drop in the share price, since it's now virtually flat for the year after a promising few quarters.

Even after such a large drop in price, given close to half the companies operating in China's Chemicals industry have price-to-sales ratios (or "P/S") below 2.2x, you may still consider Malion New Materials as a stock to potentially avoid with its 3.1x 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 as high as it is.

What Does Malion New Materials' P/S Mean For Shareholders?

For example, consider that Malion New Materials' financial performance has been poor lately as its revenue has been in decline. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Revenue Growth Forecasted For Malion New Materials?

The only time you'd be truly comfortable seeing a P/S as high as Malion New Materials' is when the company's growth is on track to outshine the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 14%. Regardless, revenue has managed to lift by a handy 6.1% in aggregate from three years ago, thanks to the earlier period of growth. Although it's been a bumpy ride, it's still fair to say the revenue growth recently has been mostly respectable for the company.

This is in contrast to the rest of the industry, which is expected to grow by 25% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this in mind, we find it worrying that Malion New Materials' P/S exceeds that of its industry peers. 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 Malion New Materials' P/S

There's still some elevation in Malion New Materials' P/S, even if the same can't be said for its share price recently. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Malion New Materials revealed its poor three-year revenue trends aren't detracting from the P/S as much as we though, given they look worse than current industry expectations. 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 there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.
