Techtronic Industries Company Limited's (HKG:669) price-to-earnings (or "P/E") ratio of 22.2x might make it look like a strong sell right now compared to the market in Hong Kong, where around half of the companies have P/E ratios below 9x and even P/E's below 4x 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.

Recent times haven't been advantageous for Techtronic Industries as its earnings have been falling quicker than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. If not, then existing shareholders may be very nervous about the viability of the share price.
