StarHub Ltd's (SGX:CC3) price-to-earnings (or "P/E") ratio of 15.2x might make it look like a sell right now compared to the market in Singapore, where around half of the companies have P/E ratios below 11x and even P/E's below 7x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

With its earnings growth in positive territory compared to the declining earnings of most other companies, StarHub has been doing quite well of late. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Keen to find out how analysts think StarHub's future stacks up against the industry? In that case, our free report is a great place to start.

Is There Enough Growth For StarHub?

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

Taking a look back first, we see that the company grew earnings per share by an impressive 162% last year. However, this wasn't enough as the latest three year period has seen a very unpleasant 4.8% drop in EPS in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Looking ahead now, EPS is anticipated to climb by 11% each year during the coming three years according to the analysts following the company. That's shaping up to be materially higher than the 8.5% per year growth forecast for the broader market.

With this information, we can see why StarHub is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Final Word

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

As we suspected, our examination of StarHub'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.

There are also other vital risk factors to consider before investing and we've discovered 2 warning signs for StarHub that you should be aware of.
