There's Reason For Concern Over Poly Plastic Masterbatch (SuZhou) Co.,Ltd's (SZSE:300905) Massive 49% Price Jump

The Poly Plastic Masterbatch (SuZhou) Co.,Ltd (SZSE:300905) share price has done very well over the last month, posting an excellent gain of 49%. The last 30 days bring the annual gain to a very sharp 35%.

After such a large jump in price, Poly Plastic Masterbatch (SuZhou)Ltd may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 38.8x, since almost half of all companies in China have P/E ratios under 29x and even P/E's lower than 18x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

Poly Plastic Masterbatch (SuZhou)Ltd certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

Poly Plastic Masterbatch (SuZhou)Ltd's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 87%. However, this wasn't enough as the latest three year period has seen a very unpleasant 39% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 35% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Poly Plastic Masterbatch (SuZhou)Ltd is trading at a P/E higher than the market. 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/E falls to levels more in line with the recent negative growth rates.

The Bottom Line On Poly Plastic Masterbatch (SuZhou)Ltd's P/E

The large bounce in Poly Plastic Masterbatch (SuZhou)Ltd's shares has lifted the company's P/E to a fairly high level. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Poly Plastic Masterbatch (SuZhou)Ltd currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
