The purpose of this thesis is to examine if the return is higher for active savers than fornon-active savers in the Swedish premium pension system. The timeframe of the study is 2001 – 2009 and it is presumed that the pension saver only makes one choice of funds in the Swedish premium pension system and then keeps these. No regard has been taken to the different fees associated with funds and the management of them. The study is based on a quantitative approach since it employs numerical secondary data and it has a deductive approach given that it is based on existing theory. The study was conductedby comparing the average return of the Swedish premium savings fund with the average return of three different fund portfolios with different risk levels recommended by Morningstar. The study shows that those who place their savings in the recommended fund portfolios receive a higher return in two out of three fund portfolios. However,being an active saver can be associated with higher risk and an active choice is not always profitable.
