Jiangsu Broadcasting Cable Information Network Corporation Limited's (SHSE:600959) price-to-earnings (or "P/E") ratio of 46.5x 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 33x and even P/E's below 19x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

Jiangsu Broadcasting Cable Information Network has been doing a good job lately as it's been growing earnings at a solid pace. It might be that many expect the respectable earnings performance to beat most other companies over the coming period, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders may be a little nervous about the viability of the share price.

Is There Enough Growth For Jiangsu Broadcasting Cable Information Network?

Jiangsu Broadcasting Cable Information Network's P/E ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 15%. The latest three year period has also seen an excellent 38% overall rise in EPS, aided by its short-term performance. 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 44% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that Jiangsu Broadcasting Cable Information Network's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with recent growth rates.

What We Can Learn From Jiangsu Broadcasting Cable Information Network's P/E?

We've established that Jiangsu Broadcasting Cable Information Network currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
