With a price-to-earnings (or "P/E") ratio of 15.6x Wolong Electric Group Co.,Ltd. (SHSE:600580) may be sending very bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 35x and even P/E's higher than 64x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

Wolong Electric GroupLtd has been struggling lately as its earnings have declined faster than most other companies. It seems that many are expecting the dismal earnings performance to persist, which has repressed the P/E. You'd much rather the company wasn't bleeding earnings if you still believe in the business. If not, then existing shareholders will probably struggle to get excited about the future direction of the share price.
