Radian Group Inc.'s (NYSE:RDN) price-to-earnings (or "P/E") ratio of 8.4x might make it look like a strong buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 18x and even P/E's above 33x are quite common. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

With earnings that are retreating more than the market's of late, Radian Group has been very sluggish. The P/E is probably low because investors think this poor earnings performance isn't going to improve at all. You'd much rather the company wasn't bleeding earnings if you still believe in the business. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

How Is Radian Group's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as depressed as Radian Group's is when the company's growth is on track to lag 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 14%. Still, the latest three year period has seen an excellent 103% overall rise in EPS, in spite of its unsatisfying short-term performance. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Shifting to the future, estimates from the five analysts covering the company suggest earnings should grow by 1.3% each year over the next three years. Meanwhile, the rest of the market is forecast to expand by 10% each year, which is noticeably more attractive.

In light of this, it's understandable that Radian Group's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Bottom Line On Radian Group's P/E

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.

We've established that Radian Group maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. It's hard to see the share price rising strongly in the near future under these circumstances.
