Abstract (Summary)
Introduction: Sweden has a long tradition of pension systems, as early as 1914 was the first system implemented. The system has been changed a number of times and in 1998 was the Premium pension authority (PPM) system introduced. PPM is a mixture of a distribution-based system and fund-based system. 16 per cent of an individual’s income is devoted to the distribution-based system for financing today’s pensions. 2.5 per cent of an individual’s income is looked in the fund-based system and can be invested by the individual in different funds. The PPM system has been a target for much criticism since earlier studies has shown that the Swedes do not make an active choice nor have the demanded knowledge. Diversification is best explained through the saying; not to place all your eggs in the same basket. Diversification is a measure of how well an investor has succeeded to spread the risk of the portfolio by allocating assets in different securities. Purpose: The purpose of this thesis is to study whether the Swedish inhabitant’s pension portfolios within the PPM system are diversified. This purpose has been chosen because no studies have been made with an identical aim and also that the risk with holding a poorly diversified portfolio is grave. Methodology: A quantitative approach has been chosen since the aim of the thesis is to draw conclusions based on large sample numbers. Solitary secondary data, received from PPM, has been used to conduct the empirical study. To simplify the study limitations of information have been made; in the study samples of 100 individuals and 50 funds have been used. A Delimitation of the study is that only fund data for the last three years has been used. Despite the scarcities of the thesis the authors claim that the thesis has high validity and reliability. Conclusions: When benchmarking the individual portfolios against the efficient frontier a number of results were revealed and they all ended up in the same conclusion that the Swede’s pension portfolio within the PPM system is insufficient diversified. Implication for management of the PPM system To conduct further studies with the aim to get knowledge; why the investments are poorly diversified and find ways to transform the suggestions of the study into practice.
