The China Tangshang Holdings Limited (HKG:674) share price has fared very poorly over the last month, falling by a substantial 29%. Looking back over the past twelve months the stock has been a solid performer regardless, with a gain of 14%.

In spite of the heavy fall in price, it's still not a stretch to say that China Tangshang Holdings' price-to-earnings (or "P/E") ratio of 9.5x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

China Tangshang Holdings certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. 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.

How Is China Tangshang Holdings' Growth Trending?

The only time you'd be comfortable seeing a P/E like China Tangshang Holdings' is when the company's growth is tracking the market closely.

Retrospectively, the last year delivered an exceptional 311% gain to the company's bottom line. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Comparing that to the market, which is predicted to deliver 25% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

With this information, we find it interesting that China Tangshang Holdings 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. They may be setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Key Takeaway

Following China Tangshang Holdings' share price tumble, its P/E is now hanging on to the median market P/E. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of China Tangshang Holdings revealed its three-year earnings trends aren't impacting its P/E as much as we would have predicted, given they look worse than current market expectations. 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.
