First American Financial Corporation's (NYSE:FAF) price-to-earnings (or "P/E") ratio of 78.4x might make it look like a strong sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 19x and even P/E's below 11x are quite common. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

First American Financial hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like First American Financial's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 61%. This means it has also seen a slide in earnings over the longer-term as EPS is down 92% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 394% during the coming year according to the three analysts following the company. That's shaping up to be materially higher than the 15% growth forecast for the broader market.

With this information, we can see why First American Financial is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Final Word

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that First American Financial maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. 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.
