When close to half the companies in China have price-to-earnings ratios (or "P/E's") below 34x, you may consider Suzhou TFC Optical Communication Co., Ltd. (SZSE:300394) as a stock to avoid entirely with its 65x 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.

Suzhou TFC Optical Communication certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.
