The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. One great example is Boston Scientific Corporation (NYSE:BSX) which saw its share price drive 221% higher over five years. Also pleasing for shareholders was the 13% gain in the last three months.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Boston Scientific's earnings per share are down 18% per year, despite strong share price performance over five years.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

In contrast revenue growth of 9.9% 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 49% over the last year. That's better than the annualised return of 26% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
