Vanov Holdings Company Limited (HKG:2260) shareholders won't be pleased to see that the share price has had a very rough month, dropping 27% and undoing the prior period's positive performance. Looking at the bigger picture, even after this poor month the stock is up 67% in the last year.

Even after such a large drop in price, Vanov Holdings may still be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 14.2x, since almost half of all companies in Hong Kong have P/E ratios under 8x and even P/E's lower than 5x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

For example, consider that Vanov Holdings' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. 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 steep as Vanov Holdings' is when the company's growth is on track to outshine the market decidedly.

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 11%. The last three years don't look nice either as the company has shrunk EPS by 10% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 22% shows it's an unpleasant look.

In light of this, it's alarming that Vanov Holdings' 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. 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 Bottom Line On Vanov Holdings' P/E

Even after such a strong price drop, Vanov Holdings' P/E still exceeds the rest of the market significantly. 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 Vanov Holdings 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.
