Ger högre risk verkligen en högre avkastning? : En kvantitativ studie om risk och avkastning på Frankfurtbörsen

Sammanfattning: As an investor, the goal is to get as high return at as low risk as possible on an invested stock. Theories show a positive relationship between high risk and high return. However, there are studies that contradict this statement, which creates misleading investors. The purpose of this quantitative study was to investigate the relationship between risk and return, to see if increased risk really leads to a higher return. The study is limited to the Frankfurt Stock Exchange between the period 2010-2019. The index examined is Germany's largest index DAX, which comprised 30 shares on 1 January 2015. Four portfolios have been created: two low-risk portfolios and two high-risk portfolios, where fictitious investments were made to then measure the return after a period of five years. The two risk measures used in the study for calculation are beta value and volatility. The beta value has been used in CAPM to calculate the expected return. The results of the study using correlation and multiple regression analysis obtained a negative significant relationship between risk and return. The portfolios also showed a negative relationship between higher risk and higher return. The results from this study are consistent with many previous studies, but the variables used to measure and define risk can be questioned.
