With a price-to-earnings (or "P/E") ratio of 34.9x Deluxe Corporation (NYSE:DLX) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 16x and even P/E's lower than 9x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Recent times haven't been advantageous for Deluxe as its earnings have been falling quicker than most other companies. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be very nervous about the viability of the share price.

Does Growth Match The High P/E?

Deluxe's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 61%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 380% in total over the last three years. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Shifting to the future, estimates from the three analysts covering the company suggest earnings should grow by 148% over the next year. Meanwhile, the rest of the market is forecast to only expand by 11%, which is noticeably less attractive.

In light of this, it's understandable that Deluxe's P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

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

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that Deluxe 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. It's hard to see the share price falling strongly in the near future under these circumstances.

Having said that, be aware Deluxe is showing 4 warning signs in our investment analysis, and 1 of those is a bit concerning.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with a strong growth track record, trading on a low P/E.
