Ipsen's (EPA:IPN) investors will be pleased with their strong 186% return over the last five years

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 when you pick a company that is really flourishing, you can make more than 100%. Long term Ipsen S.A. (EPA:IPN) shareholders would be well aware of this, since the stock is up 170% in five years. Then again, the 9.5% share price decline hasn't been so fun for shareholders. This could be related to the recent financial results, released recently - you can catch up on the most recent data by reading our company report.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

Check out our latest analysis for Ipsen

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 the five years of share price growth, Ipsen moved from a loss to profitability. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Ipsen's TSR for the last 5 years was 186%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that Ipsen shareholders have received a total shareholder return of 4.4% over the last year. Of course, that includes the dividend. Having said that, the five-year TSR of 23% a year, is even better. Potential buyers might understandably feel they've missed the opportunity, but it's always possible business is still firing on all cylinders. It's always interesting to track share price performance over the longer term. But to understand Ipsen better, we need to consider many other factors.
