The Hengbao Co.,Ltd. (SZSE:002104) share price has fared very poorly over the last month, falling by a substantial 25%. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 31% share price drop.

Even after such a large drop in price, it's still not a stretch to say that HengbaoLtd's price-to-earnings (or "P/E") ratio of 28.1x right now seems quite "middle-of-the-road" compared to the market in China, where the median P/E ratio is around 28x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Recent times have been quite advantageous for HengbaoLtd as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to wane, which has kept the P/E from rising. 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 not quite in favour.

Does Growth Match The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like HengbaoLtd's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 59% gain to the company's bottom line. The latest three year period has also seen an excellent 118% overall rise in EPS, aided by its short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

This is in contrast to the rest of the market, which is expected to grow by 42% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it interesting that HengbaoLtd is trading at a fairly similar P/E to the market. It seems most investors are ignoring the fairly limited recent growth rates and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as a continuation of recent earnings trends is likely to weigh down the shares eventually.

The Bottom Line On HengbaoLtd's P/E

HengbaoLtd's plummeting stock price has brought its P/E right back to the rest of the market. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that HengbaoLtd currently trades on a higher than expected P/E since its recent three-year growth is lower than the wider market forecast. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
