Harbin Air Conditioning Co.,Ltd. (SHSE:600202) shareholders won't be pleased to see that the share price has had a very rough month, dropping 25% and undoing the prior period's positive performance. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 31% share price drop.

In spite of the heavy fall in price, Harbin Air ConditioningLtd may still be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 67.2x, since almost half of all companies in China have P/E ratios under 29x and even P/E's lower than 18x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For example, consider that Harbin Air ConditioningLtd's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Growth For Harbin Air ConditioningLtd?

Harbin Air ConditioningLtd's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered a frustrating 46% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 59% in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that Harbin Air ConditioningLtd is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Key Takeaway

Harbin Air ConditioningLtd's shares may have retreated, but its P/E is still flying high. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Harbin Air ConditioningLtd revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
