The Sharpe ratio is adequate for evaluating investment funds when the returns ofthose funds are normally distributed and the investor intends to place all his risky assetsinto just one investment fund. Hedge fund returns differ significantly from anormal distribution. For this reason, other...

Data envelopment analysis (DEA) is a nonparametric method from the area of operationsresearch that measures the relationship of produced outputs to assignedinputs and determines an efficiency score. This efficiency score can be interpretedas a performance measure in investment analysis. Recent...

This paper examines properties of mean-variance inefficient proxies with respect to producing a linear relation between expected returns and betas. The numerical results of a Monte Carlo simulation show that in the CAPM slightly inefficient, positively weighted proxies cause an almost perfect...

Ende der 90er Jahre schien eine intensive Auswahl der Investments kaum notwendig, da fast jede Aktienanlage deutliche Kursgewinne versprach. Nachdem jähen Absturz an den Börsen haben die Anleger einen beträchtlichen Teilihres Aktienvermögens verloren. Damit rücken wieder verstärkt...

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...

Derivatives exchanges often determine collateral requirements, which are fundamental to market safety, with dated risk models assuming normal returns. However, derivatives returns are heavy-tailed, which leads to the systematic under-collection of collateral (margin). This paper uses extreme...

We consider the randomness of market trade as the origin of price and return stochasticity. We look at time series of trade values and volumes as random variables during the averaging interval Δ and describe the dependences of market-based volatilities of price and return on the volatilities...

This work aims to initiate a reflection on the awareness of environmental, social, and corporate governance issues, summarized in the acronym ESG (Environmental, Social, Governance), among Italian SMEs. The integration of ESG issues into business models has led to an expansion of the risk...

We examine novel data on the detailed investment decisions of professional value investors. We find evidence that value investors are not easily defined: they exploit traditional tangible asset valuation discrepancies such as buying high book-to-market stocks, but spend more time analyzing...

Evidence suggests that arbitragers exchange investment ideas. We analyze why and under what circumstances sharing occurs. Our model suggests that sharing ideas will lead to the following: more efficient asset prices, larger arbitrager profits, and correlated arbitrager returns. We predict that...
