Jack Henry & Associates, Inc.'s (NASDAQ:JKHY) price-to-earnings (or "P/E") ratio of 34.8x 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 18x and even P/E's below 10x 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, Jack Henry & Associates 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. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is Jack Henry & Associates' Growth Trending?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Jack Henry & Associates' to be considered reasonable.

If we review the last year of earnings growth, the company posted a worthy increase of 4.2%. The latest three year period has also seen a 27% overall rise in EPS, aided somewhat by its short-term performance. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 11% each year over the next three years. Meanwhile, the rest of the market is forecast to expand by 10% each year, which is not materially different.

With this information, we find it interesting that Jack Henry & Associates is trading at a high P/E compared to the market. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

The Bottom Line On Jack Henry & Associates' P/E

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 Jack Henry & Associates currently trades on a higher than expected P/E since its forecast growth is only in line with the wider market. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
