Ball Corporation's (NYSE:BALL) price-to-earnings (or "P/E") ratio of 33.1x 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 17x and even P/E's below 9x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Ball 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.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Ball would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings growth, the company posted a terrific increase of 66%. However, this wasn't enough as the latest three year period has seen a very unpleasant 8.8% drop in EPS in aggregate. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 20% per annum over the next three years. That's shaping up to be materially higher than the 10% each year growth forecast for the broader market.

With this information, we can see why Ball 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 Key Takeaway

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Ball 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.
