It hasn't been the best quarter for Lerøy Seafood Group ASA (OB:LSG) shareholders, since the share price has fallen 11% in that time. But that doesn't change the fact that the returns over the last five years have been very strong. In fact, the share price is 120% higher today. Generally speaking the long term returns will give you a better idea of business quality than short periods can. The more important question is whether the stock is too cheap or too expensive today. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 15% drop, in the last year.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

Over half a decade, Lerøy Seafood Group managed to grow its earnings per share at 10% a year. This EPS growth is slower than the share price growth of 17% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Lerøy Seafood Group the TSR over the last 5 years was 152%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While it's certainly disappointing to see that Lerøy Seafood Group shares lost 12% throughout the year, that wasn't as bad as the market loss of 18%. Longer term investors wouldn't be so upset, since they would have made 20%, each year, over five years. In the best case scenario the last year is just a temporary blip on the journey to a brighter future. 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.
