When close to half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") below 8x, you may consider Hengtai Securities Co., Ltd (HKG:1476) as a stock to avoid entirely with its 19.8x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

For example, consider that Hengtai Securities' financial performance has been poor lately as it's earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do 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.

Is There Enough Growth For Hengtai Securities?

The only time you'd be truly comfortable seeing a P/E as steep as Hengtai Securities' is when the company's growth is on track to outshine the market decidedly.

Retrospectively, the last year delivered a frustrating 34% decrease to the company's bottom line. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 17% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

With this information, we find it concerning that Hengtai Securities is trading at a P/E higher than the market. 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 Final Word

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that Hengtai Securities currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. When we see weak earnings with slower than market growth, 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.
