When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 29x, you may consider CETC Acoustic-Optic-Electronic Technology Inc. (SHSE:600877) as a stock to avoid entirely with its 66.5x P/E ratio. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.
As an illustration, earnings have deteriorated at CETC Acoustic-Optic-Electronic Technology 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?
In order to justify its P/E ratio, CETC Acoustic-Optic-Electronic Technology would need to produce outstanding growth well 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 4.1%. This means it has also seen a slide in earnings over the longer-term as EPS is down 8.5% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.
Comparing that to the market, which is predicted to deliver 42% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.
With this information, we find it concerning that CETC Acoustic-Optic-Electronic Technology is trading at a P/E higher than 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 very 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 Bottom Line On CETC Acoustic-Optic-Electronic Technology's P/E
We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.
Our examination of CETC Acoustic-Optic-Electronic Technology revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with CETC Acoustic-Optic-Electronic Technology, and understanding should be part of your investment process.
