Despite an already strong run, Changhua Holding Group Co., Ltd. (SHSE:605018) shares have been powering on, with a gain of 28% in the last thirty days. But the gains over the last month weren't enough to make shareholders whole, as the share price is still down 5.3% in the last twelve months.

Even after such a large jump in price, you could still be forgiven for feeling indifferent about Changhua Holding Group's P/E ratio of 34.7x, since the median price-to-earnings (or "P/E") ratio in China is also close to 37x. 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.

With earnings growth that's exceedingly strong of late, Changhua Holding Group has been doing very well. 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?

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

Retrospectively, the last year delivered an exceptional 44% gain to the company's bottom line. However, this wasn't enough as the latest three year period has seen a very unpleasant 37% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Changhua Holding Group is trading at a fairly similar P/E to 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 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 Key Takeaway

Changhua Holding Group appears to be back in favour with a solid price jump getting its P/E back in line with most other companies. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Changhua Holding Group currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. Right now we are uncomfortable with the P/E as this earnings performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
