Yamada Green Resources Limited (SGX:BJV) shareholders have had their patience rewarded with a 28% share price jump in the last month. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Following the firm bounce in price, Yamada Green Resources' price-to-earnings (or "P/E") ratio of 26x might make it look like a strong sell right now compared to the market in Singapore, where around half of the companies have P/E ratios below 12x and even P/E's below 7x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

Yamada Green Resources certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.
