A Broadband Vision of the DAX over Time

We present an analysis of the performance of the DAX, German's major stock market index, over the last two years. Our analysis is broader than conventional benchmark approaches because we study the properties of all feasible portfolios, i.e. portfolios composed given the same investment opportunity set and also given the same constraints as implied by the definition of the DAX. We estimate the distribution of performance values of all feasible portfolios according to different performance measures and evaluate the position of the DAX with respect to this feasible set. As in existing approaches, our analysis describes the 'average' development of the market over time. In addition, our analysis provides an insight into the development of the dynamics of the market over time by following the dispersion of the performance distributions over time.
