Pulike Biological Engineering, Inc. (SHSE:603566) shareholders won't be pleased to see that the share price has had a very rough month, dropping 27% and undoing the prior period's positive performance. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 44% in that time.

Although its price has dipped substantially, given about half the companies in China have price-to-earnings ratios (or "P/E's") above 32x, you may still consider Pulike Biological Engineering as an attractive investment with its 24.7x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Recent times have been pleasing for Pulike Biological Engineering as its earnings have risen in spite of the market's earnings going into reverse. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

How Is Pulike Biological Engineering's Growth Trending?

Pulike Biological Engineering's P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 42%. As a result, it also grew EPS by 21% in total over the last three years. Accordingly, shareholders would have probably been satisfied with the medium-term rates of earnings growth.

Shifting to the future, estimates from the eight analysts covering the company suggest earnings should grow by 33% over the next year. With the market predicted to deliver 42% growth , the company is positioned for a weaker earnings result.

In light of this, it's understandable that Pulike Biological Engineering's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

What We Can Learn From Pulike Biological Engineering's P/E?

The softening of Pulike Biological Engineering's shares means its P/E is now sitting at a pretty low 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.

As we suspected, our examination of Pulike Biological Engineering's analyst forecasts revealed that its inferior earnings outlook is contributing to its low P/E. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio.
