Lingbao Gold Group Company Ltd. (HKG:3330) shares have continued their recent momentum with a 28% gain in the last month alone. The last month tops off a massive increase of 160% in the last year.

Since its price has surged higher, given close to half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") below 10x, you may consider Lingbao Gold Group as a stock to avoid entirely with its 21.6x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

The earnings growth achieved at Lingbao Gold Group over the last year would be more than acceptable for most companies. 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. If not, then existing shareholders may be a little nervous about the viability of the share price.
