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 von Kapitalanlagen entwickelt. Die moderneren Performancemaße verlangen keine Konstanz der Risikomaße...

This paper shows how to introduce liquidity into the well known mean-variance framework of portfolio selection. Either by estimating mean-variance liquidity constrained frontiers or directly estimating optimal portfolios for alternative levels of risk aversion and preference for liquidity, we...

Dans cet article, pour etendre la theorie du consommateur a ses choix d'epargne et de placements, on utilise a la fois la theorie usuelle, celle des caracteristiques et celle du raisonnement quantitatif. On en deduit un systeme complet de demandes comprenant simultanement les quantites de biens...

This paper prepared for the Handbook of Statistics (Vol.14: "Statistical Methods in Finance"), surveys the subject of stochastic volatility. the following subjects are covered: volatility in financial markets (instantaneous volatility of asset returns, implied volatilities in option prices and...

Risk a basic parameter of portfolio selection and its modelling involves some difficulties. Thus, more and more researchers try to find a solution to this problem proposing other measures than the classic ones used in portfolio selection. On the other hand, Multicriteria Decision Aid has known a...

Bu çalışmada İMKB’de işlem gören hisse senetlerinin toplam riskleri, 1997-2004 dönemi esas alınarak piyasa riski, endüstri riski ve firma riski bileşenlerine ayrılmıştır. Toplam risk içinde piyasa riskinin ağırlığı kriz dönemlerinde artmakta, istikrar dönemlerinde...

This paper finds evidence that firms may manipulate their systematic risk. This contrasts with previously held views that changes in estimates of systematic risk were an artefact of the estimators used. The central finding is that firms take actions which result in their equity betas adjusting...

Se han analizado 6 grupos de variables en un intento de explicar el retorno futuro de las acciones utilizando el CAPM en España. Específicamente, se han realizado variadas simulaciones históricas y regresiones de corte transversal de los retornos de las acciones componentes de la muestra...

We estimate a state-dependent multifactor model with two endogenous states. Its pricing accuracy is slightly superior to that of the Fama and French (1993, 1996) model. We have evidence for dramatically increased factor loadings for distress factors in one state. These results have implications...

We use semi-parametric bin tests, regression analyses and copula modeling techniques to identify the relationship between temperature and stock market returns. After examining 25 international stock markets, we find that the negative correlation is statistically significant in individual...
