Traditional risk-adjusted performance measures, such as the Sharpe ratio, the Treynor index or Jensen's alpha, based on the mean-variance framework, are widely used to rank mutual funds. However, performance measures that consider risk by taking into account only losses, such as Value-at-Risk...

This paper provides evidence on the hypothesis that many behavioral finance patterns are so deeply rooted in human behavior that they are difficult to overcome by learning. We test this on a target group which has undoubtedly very strong incentives to learn efficient behavior, i.e. fund...

This paper provides survey evidence on the influence of training on behavioral finance on professional fund managers' perception and investment behavior. In particular, it examines whether 'trained' fund managers differ from the 'untrained' ones in their perception of markets and themselves as...

The mutual funds' returns, inter alia, are dependent on fund managers' performance. This makes human capital efficiency very central for consistent risk-adjusted performance. The persistence in performance becomes more critical during periods of high turbulence, like the one we are experiencing...

We examine overconfidence among equity mutual fund managers. While overconfidencehas been extensively documented among retail investors, evidence fromprofessional investors is scarce. Consistent with theories of overconfidence, we findthat fund managers trade more after good past performance....

Neben den klassischen Performancemaßen, wie der Sharpe-Ratio, der Treynor-Ratio und dem Jensen-Alpha wurden in den letzten Jahrzehnten weiterführende Ansätze für die Analyse und Bewertung vonKapitalanlagen entwickelt. Die moderneren Performancemaße verlangen keine Konstanz derRisikomaße...

We argue that active management's popularity is not puzzling despite the industry's poor track record. Our explanation features decreasing returns to scale: As the industry's size increases, every manager's ability to outperform passive benchmarks declines. The poor track record occurred before...
