Despite the downward trend in earnings at Boston Scientific (NYSE:BSX) the stock climbs 3.8%, bringing five-year gains to 224%

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, you can make far more than 100% on a really good stock. One great example is Boston Scientific Corporation (NYSE:BSX) which saw its share price drive 224% higher over five years. Also pleasing for shareholders was the 13% gain in the last three months.

The past week has proven to be lucrative for Boston Scientific investors, so let's see if fundamentals drove the company's five-year performance.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

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

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 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 good to see that Boston Scientific has rewarded shareholders with a total shareholder return of 53% in the last twelve months. That's better than the annualised return of 27% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. It's always interesting to track share price performance over the longer term. But to understand Boston Scientific better, we need to consider many other factors.
