Despite an already strong run, Shanghai Kai Kai Industry Company Limited (SHSE:900943) shares have been powering on, with a gain of 25% in the last thirty days. The last 30 days bring the annual gain to a very sharp 60%.

Although its price has surged higher, Shanghai Kai Kai Industry may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 27.2x, since almost half of all companies in China have P/E ratios greater than 32x and even P/E's higher than 59x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Shanghai Kai Kai Industry certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. 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.

How Is Shanghai Kai Kai Industry's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as low as Shanghai Kai Kai Industry's is when the company's growth is on track to lag the market.

If we review the last year of earnings growth, the company posted a terrific increase of 202%. The strong recent performance means it was also able to grow EPS by 80% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.

With this information, we can see why Shanghai Kai Kai Industry is trading at a P/E lower than the market. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

Despite Shanghai Kai Kai Industry's shares building up a head of steam, its P/E still lags most other companies. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.
