| Abstract: | In the pst years, the understanding of risk as standard deviation or variance has been questioned frequently. Instead of these measures, the probability of failure to attain a prespecified target return has been proposed as a more intuitive measure of risk. This paper shows under which conditions the traditional Mean-Variance-approach according to Markowitz can be applied to identify Safety-First- Portfolios according to Roy. A graphically motivated methodology, called Tangent-Method, is developed to calculate the efficient frontier. According to the modified understanding of risk, a new presentation of portfolios in generalized Mean-Lower-Partial-Moment-World with varying targets is proposed. |
