When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 26x, you may consider Shenzhen Yan Tian Port Holdings Co.,Ltd. (SZSE:000088) as a stock to potentially avoid with its 32x P/E ratio. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

Earnings have risen firmly for Shenzhen Yan Tian Port HoldingsLtd recently, which is pleasing to see. 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?

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

If we review the last year of earnings growth, the company posted a terrific increase of 16%. Still, incredibly EPS has fallen 33% in total from three years ago, which is quite disappointing. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 41% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Shenzhen Yan Tian Port HoldingsLtd's P/E sits above the majority of other companies. 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 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 Shenzhen Yan Tian Port HoldingsLtd 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.
