When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 32x, you may consider Guomai Technologies, Inc. (SZSE:002093) as a stock to avoid entirely with its 64.1x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Guomai Technologies certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

In order to justify its P/E ratio, Guomai Technologies would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings growth, the company posted a terrific increase of 46%. As a result, it also grew EPS by 29% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 38% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that Guomai Technologies' P/E sits above the majority of other companies. 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.

The Key Takeaway

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.

We've established that Guomai Technologies currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
