Those holding China Publishing & Media Holdings Co., Ltd. (SHSE:601949) shares would be relieved that the share price has rebounded 26% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Looking back a bit further, it's encouraging to see the stock is up 39% in the last year.

Although its price has surged higher, China Publishing & Media Holdings may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 20.2x, since almost half of all companies in China have P/E ratios greater than 30x and even P/E's higher than 55x are not unusual. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

China Publishing & Media Holdings has been doing a good job lately as it's been growing earnings at a solid pace. One possibility is that the P/E is low because investors think this respectable earnings growth might actually underperform the broader market in the near future. If you 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.

How Is China Publishing & Media Holdings' Growth Trending?

There's an inherent assumption that a company should underperform the market for P/E ratios like China Publishing & Media Holdings' to be considered reasonable.

If we review the last year of earnings growth, the company posted a terrific increase of 15%. Still, EPS has barely risen at all from three years ago in total, which is not ideal. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 41% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we are not surprised that China Publishing & Media Holdings is trading at a P/E lower than the market. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

The latest share price surge wasn't enough to lift China Publishing & Media Holdings' P/E close to the market median. 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 China Publishing & Media Holdings revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. 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.
