Sichuan Em Technology Co., Ltd. (SHSE:601208) shareholders are no doubt pleased to see that the share price has bounced 26% in the last month, although it is still struggling to make up recently lost ground. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 23% over that time.

Even after such a large jump in price, Sichuan Em Technology may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 26x, since almost half of all companies in China have P/E ratios greater than 31x and even P/E's higher than 56x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

Sichuan Em Technology has been struggling lately as its earnings have declined faster than most other companies. It seems that many are expecting the dismal earnings performance to persist, which has repressed the P/E. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

How Is Sichuan Em Technology's Growth Trending?

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 11%. Still, the latest three year period has seen an excellent 98% overall rise in EPS, in spite of its unsatisfying short-term performance. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Shifting to the future, estimates from the six analysts covering the company suggest earnings should grow by 46% over the next year. With the market only predicted to deliver 41%, the company is positioned for a stronger earnings result.

In light of this, it's peculiar that Sichuan Em Technology's P/E sits below the majority of other companies. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

What We Can Learn From Sichuan Em Technology's P/E?

Despite Sichuan Em Technology'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.

Our examination of Sichuan Em Technology's analyst forecasts revealed that its superior earnings outlook isn't contributing to its P/E anywhere near as much as we would have predicted. When we see a strong earnings outlook with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. At least price risks look to be very low, but investors seem to think future earnings could see a lot of volatility.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 2 warning signs with Sichuan Em Technology (at least 1 which shouldn't be ignored), and understanding them should be part of your investment process.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
