Sampo Oyj's (HEL:SAMPO) investors will be pleased with their decent 99% return over the last five years

When we invest, we're generally looking for stocks that outperform the market average. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. To wit, the Sampo Oyj share price has climbed 37% in five years, easily topping the market return of 0.7% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 21%, including dividends.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, Sampo Oyj achieved compound earnings per share (EPS) growth of 8.8% per year. The EPS growth is more impressive than the yearly share price gain of 6% over the same period. Therefore, it seems the market has become relatively pessimistic about the company.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Sampo Oyj's TSR for the last 5 years was 99%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Sampo Oyj shareholders have received a total shareholder return of 21% over one year. And that does include the dividend. That's better than the annualised return of 15% 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. 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.
