With a price-to-earnings (or "P/E") ratio of 7.9x White Mountains Insurance Group, Ltd. (NYSE:WTM) may be sending very bullish signals at the moment, given that almost half of all companies in the United States have P/E ratios greater than 20x and even P/E's higher than 36x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

Recent times have been quite advantageous for White Mountains Insurance Group as its earnings have been rising very briskly. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Is There Any Growth For White Mountains Insurance Group?

The only time you'd be truly comfortable seeing a P/E as depressed as White Mountains Insurance Group's is when the company's growth is on track to lag the market decidedly.

If we review the last year of earnings growth, the company posted a terrific increase of 157%. The strong recent performance means it was also able to grow EPS by 318% in total over the last three years. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

This is in contrast to the rest of the market, which is expected to grow by 15% over the next year, materially lower than the company's recent medium-term annualised growth rates.

In light of this, it's peculiar that White Mountains Insurance Group's P/E sits below the majority of other companies. It looks like most investors are not convinced the company can maintain its recent growth rates.

What We Can Learn From White Mountains Insurance Group's P/E?

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.

Our examination of White Mountains Insurance Group revealed its three-year earnings trends aren't contributing to its P/E anywhere near as much as we would have predicted, given they look better than current market expectations. When we see strong earnings with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. At least price risks look to be very low if recent medium-term earnings trends continue, but investors seem to think future earnings could see a lot of volatility.
