When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 34x, you may consider Guizhou Guihang Automotive Components Co.,Ltd (SHSE:600523) as a stock to potentially avoid with its 40.9x P/E ratio. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

Guizhou Guihang Automotive ComponentsLtd has been doing a good job lately as it's been growing earnings at a solid pace. One possibility is that the P/E is high because investors think this respectable 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?

Guizhou Guihang Automotive ComponentsLtd'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, we see that the company grew earnings per share by an impressive 20% last year. Still, incredibly EPS has fallen 13% in total from three years ago, which is quite disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 44% shows it's an unpleasant look.

In light of this, it's alarming that Guizhou Guihang Automotive ComponentsLtd's P/E sits above the majority of other companies. 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. 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

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.

We've established that Guizhou Guihang Automotive ComponentsLtd currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.

It is also worth noting that we have found 2 warning signs for Guizhou Guihang Automotive ComponentsLtd that you need to take into consideration.
