With a price-to-earnings (or "P/E") ratio of 32.9x AIA Group Limited (HKG:1299) may be sending very bearish signals at the moment, given that almost half of all companies in Hong Kong have P/E ratios under 8x and even P/E's lower than 4x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

While the market has experienced earnings growth lately, AIA Group's earnings have gone into reverse gear, which is not great. One possibility is that the P/E is high because investors think this poor earnings performance will turn the corner. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For AIA Group?

The only time you'd be truly comfortable seeing a P/E as steep as AIA Group's is when the company's growth is on track to outshine the market decidedly.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 46%. This means it has also seen a slide in earnings over the longer-term as EPS is down 10.0% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Turning to the outlook, the next three years should generate growth of 36% per year as estimated by the analysts watching the company. With the market only predicted to deliver 15% per annum, the company is positioned for a stronger earnings result.

In light of this, it's understandable that AIA Group's P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Key Takeaway

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of AIA Group's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. Unless these conditions change, they will continue to provide strong support to the share price.
