Introducing Amarin (NASDAQ:AMRN), The Stock That Soared 726% In The Last Five Years

Simply Wall St

The last three months have been tough on Amarin Corporation plc (NASDAQ:AMRN) shareholders, who have seen the share price decline a rather worrying 31%. But over five years returns have been remarkably great. In fact, during that period, the share price climbed 726%. Impressive! Arguably, the recent fall is to be expected after such a strong rise. But the real question is whether the business fundamentals can improve over the long term.

We love happy stories like this one. The company should be really proud of that performance!

Amarin isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

For the last half decade, Amarin can boast revenue growth at a rate of 36% per year. Even measured against other revenue-focussed companies, that's a good result. Arguably, this is well and truly reflected in the strong share price gain of 53%(per year) over the same period. Despite the strong run, top performers like Amarin have been known to go on winning for decades. On the face of it, this looks lke a good opportunity, although we note sentiment seems very positive already.

A Different Perspective

Amarin shareholders are down 34% for the year, but the market itself is up 6.3%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 53% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
