a) Questions to be addressed

• How well do in-sample optimized Markowitz portfolios perform compared to naive strategies?
• Different methods are to be compared empirically using performance and risk measures.
• Reasons for differences in the performance of different portfolio optimizations (e.g. parameter uncertainty) are to be worked out on the basis of the literature and empirically.

b) Data set to be used

•  A data set is to be selected independently on the basis of the literature.
•  For this purpose, stock, commodity, currency and index returns are conceivable.

c) Additional information to be processed

It is necessary to use a true out-of-sample methodology to evaluate portfolios with R: "Rolling Window" or "Expanding Window" methods should be used here. These have to be programmed using the statistical software R.
