With a price-to-earnings (or "P/E") ratio of 67.6x Boston Scientific Corporation (NYSE:BSX) 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 18x and even P/E's lower than 10x 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 have been pleasing for Boston Scientific as its earnings have risen in spite of the market's earnings going into reverse. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Boston Scientific's Growth Trending?

In order to justify its P/E ratio, Boston Scientific 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 108%. Pleasingly, EPS has also lifted 236% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Looking ahead now, EPS is anticipated to climb by 26% each year during the coming three years according to the analysts following the company. Meanwhile, the rest of the market is forecast to only expand by 10% per year, which is noticeably less attractive.

With this information, we can see why Boston Scientific is trading at such a high P/E compared to the market. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

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.

As we suspected, our examination of Boston Scientific's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E.
