China General Education Group Limited (HKG:2175) shareholders would be excited to see that the share price has had a great month, posting a 34% gain and recovering from prior weakness. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

In spite of the firm bounce in price, China General Education Group may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 6.3x, since almost half of all companies in Hong Kong have P/E ratios greater than 10x and even P/E's higher than 20x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

For instance, China General Education Group's receding earnings in recent times would have to be some food for thought. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. 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.

Does Growth Match The Low P/E?

In order to justify its P/E ratio, China General Education Group would need to produce sluggish growth that's trailing the market.

Retrospectively, the last year delivered a frustrating 21% decrease to the company's bottom line. This means it has also seen a slide in earnings over the longer-term as EPS is down 35% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 23% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's understandable that China General Education Group's P/E would sit below the majority of other companies. 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 Key Takeaway
