It's not a stretch to say that ManpowerGroup Inc.'s (NYSE:MAN) price-to-earnings (or "P/E") ratio of 17x right now seems quite "middle-of-the-road" compared to the market in the United States, where the median P/E ratio is around 17x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

Recent times haven't been advantageous for ManpowerGroup as its earnings have been falling quicker than most other companies. It might be that many expect the dismal earnings performance to revert back to market averages soon, which has kept the P/E from falling. You'd much rather the company wasn't bleeding earnings if you still believe in the business. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

What Are Growth Metrics Telling Us About The P/E?

In order to justify its P/E ratio, ManpowerGroup would need to produce growth that's similar to 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 46%. Even so, admirably EPS has lifted 208% in aggregate from three years ago, notwithstanding the last 12 months. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 22% during the coming year according to the ten analysts following the company. With the market only predicted to deliver 10%, the company is positioned for a stronger earnings result.

With this information, we find it interesting that ManpowerGroup is trading at a fairly similar P/E to the market. It may be that most investors aren't convinced the company can achieve future growth expectations.
