Jiangsu Broadcasting Cable Information Network Corporation Limited's (SHSE:600959) price-to-earnings (or "P/E") ratio of 42.8x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 29x and even P/E's below 18x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

We'd have to say that with no tangible growth over the last year, Jiangsu Broadcasting Cable Information Network's earnings have been unimpressive. It might be that many are expecting an improvement to the uninspiring earnings performance over the coming period, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Jiangsu Broadcasting Cable Information Network's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as high as Jiangsu Broadcasting Cable Information Network's is when the company's growth is on track to outshine the market.

Taking a look back first, we see that there was hardly any earnings per share growth to speak of for the company over the past year. Still, the latest three year period has seen an excellent 127% overall rise in EPS, in spite of its uninspiring short-term performance. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Comparing that to the market, which is predicted to deliver 34% growth in the next 12 months, the company's momentum is pretty similar based on recent medium-term annualised earnings results.

With this information, we find it interesting that Jiangsu Broadcasting Cable Information Network is trading at a high P/E compared to the market. Apparently many investors in the company are more bullish than recent times would indicate and aren't willing to let go of their stock right now. Nevertheless, they may be setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

The Final Word

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.

Our examination of Jiangsu Broadcasting Cable Information Network revealed its three-year earnings trends aren't impacting its high P/E as much as we would have predicted, given they look similar to current market expectations. When we see average earnings with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
