The Ningbo Techmation Co.,Ltd. (SHSE:603015) share price has softened a substantial 26% over the previous 30 days, handing back much of the gains the stock has made lately. Looking back over the past twelve months the stock has been a solid performer regardless, with a gain of 13%.

Although its price has dipped substantially, given around half the companies in China have price-to-earnings ratios (or "P/E's") below 35x, you may still consider Ningbo TechmationLtd as a stock to potentially avoid with its 52.7x 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 as high as it is.

With earnings growth that's exceedingly strong of late, Ningbo TechmationLtd has been doing very well. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. 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?

The only time you'd be truly comfortable seeing a P/E as high as Ningbo TechmationLtd's is when the company's growth is on track to outshine the market.

Retrospectively, the last year delivered an exceptional 122% gain to the company's bottom line. However, this wasn't enough as the latest three year period has seen a very unpleasant 13% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 38% 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 Ningbo TechmationLtd is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. 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 Final Word

Despite the recent share price weakness, Ningbo TechmationLtd's P/E remains higher than 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.

Our examination of Ningbo TechmationLtd 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.
