Sinolink Securities Co., Ltd.'s (SHSE:600109) price-to-earnings (or "P/E") ratio of 18.9x 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 30x and even P/E's above 55x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

Sinolink Securities hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It seems that many are expecting the dour earnings performance to persist, which has repressed the P/E. If you still 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?

In order to justify its P/E ratio, Sinolink Securities would need to produce sluggish growth that's trailing the market.

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 10%. This means it has also seen a slide in earnings over the longer-term as EPS is down 34% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 6.6% per year during the coming three years according to the three analysts following the company. With the market predicted to deliver 21% growth per year, the company is positioned for a weaker earnings result.

In light of this, it's understandable that Sinolink Securities' P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Sinolink Securities' analyst forecasts revealed that its inferior earnings outlook is contributing to its low P/E. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
