Shanghai Carthane Co.,Ltd.'s (SHSE:603037) price-to-earnings (or "P/E") ratio of 22.9x 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 32x and even P/E's above 61x 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 limited.

Recent times have been quite advantageous for Shanghai CarthaneLtd as its earnings have been rising very briskly. 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 that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

What Are Growth Metrics Telling Us About The Low P/E?

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

Taking a look back first, we see that the company grew earnings per share by an impressive 35% last year. EPS has also lifted 5.5% in aggregate from three years ago, mostly thanks to the last 12 months of growth. 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 37% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Shanghai CarthaneLtd's P/E sits below the majority of other companies. 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

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.

We've established that Shanghai CarthaneLtd maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.

You always need to take note of risks, for example - Shanghai CarthaneLtd has 1 warning sign we think you should be aware of.
