Using a unique data set that contains the complete ownership structure of the German stock market, we study the momentum and contrarian trading of different investor groups. Foreign investors and financial institutions, and especially mutual funds, are momentum traders, whereas private...

Is the asset management sector a source of financial instability? This paper contributes to the debate by performing a macroprudential stress test in order to quantify systemic risks in the mutual fund sector. For this purpose we include the welldocumented flow-performance relationship as an...

Asset price processes are completely described by information processes and investors' preferences. In this paper we derive the relationship between the process of investors ́expectations of the terminal stock price and asset prices in a general continous time pricing kernel framework. To...

In a continuous-time representative investor economy with an exogenously given information process, asset prices are derived for alternative characterizations of the pricing kernel. In addition to the characterization of forward prices in a general representative investor economy a detailed...

Mutual fund risk-taking via active portfolio rebalancing varies both in the cross-section and over time. In this paper, I show that the same is true for funds' off- balance sheet risk-taking, even after controlling for on-balance sheet activities. For this purpose, I propose a novel measure of...

We study an optimal liquidation problem under the ambiguity with respect to price impact parameters. Our main results show that the value function and the optimal trading strategy can be characterized by the solution to a semi-linear PDE with superlinear gradient, monotone generator and singular...

We theoretically show that there is a fundamental disconnect be- tween the disposition effect, i.e., investors’ tendency to sell winning assets too early and losing assets too late, and its common empirical measure, namely a positive difference between the proportion of gains and losses re-...
