0 INVESTMENT RISK MEASURES BASED ON THE FLEXIBLE SKEWED GENERALIZED LOGISTIC DISTRIBUTION Panayiotis Theodossiou Department of Commerce, Finance and Shipping Cyprus University of Technology Limassol, CYPRUS theodoss@gmail.com +357 25002340 June 10. 2018 ABSTRACT This paper presents the analytical equations for the computation of value at risk (VaR), expected shortfall (ES) and downside risk measures for portfolios returns based on the flexible skewed generalized logistic distribution. These analytical equations can be easily incorporated into Excel spreadsheets for easy implementation by researchers and practitioners in the field. Keywords: downside risk, expected shortfall, flexible distributions and value at risk JEL: C46, G10, G20
