Hanwei Electronics Group Corporation (SZSE:300007) shareholders are no doubt pleased to see that the share price has bounced 28% in the last month, although it is still struggling to make up recently lost ground. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 13% over that time.

After such a large jump in price, Hanwei Electronics Group may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 33.8x, 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. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

As an illustration, earnings have deteriorated at Hanwei Electronics Group over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Hanwei Electronics Group's Growth Trending?

Hanwei Electronics Group's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 44%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Hanwei Electronics Group is trading at a P/E higher than the market. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From Hanwei Electronics Group's P/E?

Hanwei Electronics Group shares have received a push in the right direction, but its P/E is elevated too. 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.

Our examination of Hanwei Electronics Group revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
