The general pension supplement introduced in 1960 which introduced the public pension funds in Sweden. In the late 1990s the Swedish pension system was reformed and established the current structure. Today, funds are one of the most common forms of savings in Sweden and mutual funds are the most common type.

The purpose of this study is to analyze the risk-adjusted returns for the AP funds in the period 2003-2009. Study was based on five funds that are most similar and have the same mission. These funds are AP1, AP2, AP3, AP4 and AP7.

The method used in this study is mainly based on a survey of the figures and measurable units of statistical methods that have been carried out by a quantitative approach. The data treated in the study were collected from fund-related websites and fund their own website.

The results showed that there are not major differences between the various funds AP1, AP2, AP3 and AP4. AP1 and AP3 have delivered the lowest average return over the years while AP7 has the highest average yield. The differences between the funds were not great but you could see a major difference when it was risk-adjusted, then AP7 became the worst.

SIXRX or Stockholm Stock Exchange has an average return that is twice the size of the yield AP funds has delivered. All five of the AP-funds underperformed and as a group, on average by 3 % per annum for the period 2003-2009.
