Sanchuan Wisdom Technology Co., Ltd.'s (SZSE:300066) price-to-earnings (or "P/E") ratio of 18.7x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 35x and even P/E's above 64x are quite common. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Recent times have been quite advantageous for Sanchuan Wisdom Technology as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Does Growth Match The Low P/E?

There's an inherent assumption that a company should underperform the market for P/E ratios like Sanchuan Wisdom Technology's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 46% gain to the company's bottom line. As a result, it also grew EPS by 21% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been respectable for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 43% shows it's noticeably less attractive on an annualised basis.

With this information, we can see why Sanchuan Wisdom Technology is trading at a P/E lower than the market. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.
