Opera Limited's (NASDAQ:OPRA) price-to-earnings (or "P/E") ratio of 7.1x 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.

Opera certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

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

How Is Opera's Growth Trending?

In order to justify its P/E ratio, Opera would need to produce anemic growth that's substantially trailing the market.

If we review the last year of earnings growth, the company posted a terrific increase of 343%. Pleasingly, EPS has also lifted 294% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Turning to the outlook, the next three years should bring diminished returns, with earnings decreasing 8.7% per year as estimated by the six analysts watching the company. With the market predicted to deliver 10% growth per year, that's a disappointing outcome.

With this information, we are not surprised that Opera is trading at a P/E lower than the market. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

What We Can Learn From Opera's P/E?

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 Opera's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. 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.
