With a price-to-earnings (or "P/E") ratio of 37x China Resources Microelectronics Limited (SHSE:688396) may be sending bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 31x and even P/E's lower than 19x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

Recent times haven't been advantageous for China Resources Microelectronics as its earnings have been falling quicker than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. If not, then existing shareholders may be very nervous about the viability of the share price.

How Is China Resources Microelectronics' Growth Trending?

In order to justify its P/E ratio, China Resources Microelectronics would need to produce impressive growth in excess of 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 43%. Still, the latest three year period has seen an excellent 34% overall rise in EPS, in spite of its unsatisfying short-term performance. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Looking ahead now, EPS is anticipated to climb by 14% during the coming year according to the eight analysts following the company. With the market predicted to deliver 40% growth , the company is positioned for a weaker earnings result.

In light of this, it's alarming that China Resources Microelectronics' P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. There's a good chance these shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Key Takeaway

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 China Resources Microelectronics currently trades on a much higher than expected P/E since its forecast growth is lower than the wider market. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
