The Sino Gas Holdings Group Limited (HKG:1759) share price has softened a substantial 28% over the previous 30 days, handing back much of the gains the stock has made lately. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 15% in that time.

Even after such a large drop in price, it's still not a stretch to say that Sino Gas Holdings Group's price-to-earnings (or "P/E") ratio of 10.7x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

For instance, Sino Gas Holdings Group's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

Does Growth Match The P/E?

In order to justify its P/E ratio, Sino Gas Holdings Group would need to produce growth that's similar to the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 21%. The last three years don't look nice either as the company has shrunk EPS by 30% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 20% shows it's an unpleasant look.

In light of this, it's somewhat alarming that Sino Gas Holdings Group's P/E sits in line with 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. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh on the share price eventually.

The Bottom Line On Sino Gas Holdings Group's P/E

Following Sino Gas Holdings Group's share price tumble, its P/E is now hanging on to the median market P/E. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Sino Gas Holdings Group currently trades on a 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 moderate P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
