With a price-to-earnings (or "P/E") ratio of 28.5x Interparfums, Inc. (NASDAQ:IPAR) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 19x and even P/E's lower than 11x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

While the market has experienced earnings growth lately, Interparfums' earnings have gone into reverse gear, which is not great. 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.

How Is Interparfums' Growth Trending?

In order to justify its P/E ratio, Interparfums would need to produce impressive growth in excess of 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 5.3%. Still, the latest three year period has seen an excellent 44% overall rise in EPS, in spite of its unsatisfying short-term performance. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Turning to the outlook, the next three years should generate growth of 9.8% per year as estimated by the four analysts watching the company. With the market predicted to deliver 11% growth each year, the company is positioned for a comparable earnings result.

With this information, we find it interesting that Interparfums is trading at a high P/E compared to the market. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

The Final Word

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Interparfums' analyst forecasts revealed that its market-matching earnings outlook isn't impacting its high P/E as much as we would have predicted. 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.
