When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Boston Scientific Corporation (NYSE:BSX) share price has soared 182% in the last half decade. Most would be very happy with that. In more good news, the share price has risen 12% in thirty days. But this could be related to good market conditions -- stocks in its market are up 14% in the last month.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, Boston Scientific actually saw its EPS drop 15% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

In contrast revenue growth of 11% per year is probably viewed as evidence that Boston Scientific is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

A Different Perspective

It's nice to see that Boston Scientific shareholders have received a total shareholder return of 39% over the last year. That's better than the annualised return of 23% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
