Investors need performance measures particularly as a means for funds selection in the process of exanteportfolio optimization. Unfortunately, there are various performance measures recommended for differentdecision situations. Since an investor may be uncertain which kind of decision problem is...

The requirement of positive marginal utility only makes it possible to derive a restricted twofundseparation theorem for portfolio selection problems replacing the original separation theorem ofCass and Stiglitz (1970). We use our findings for a re-examination of the bias-in-beta problem in...

We consider investors with mean-variance-skewness preferences who aim at selecting oneout of F different funds and combining it optimally with the riskless asset and direct stock holdings.Direct stock holdings are either exogenously or endogenously determined. In our theoretical section,we...

The most relevant practical impediment to an application of the Markowitz portfolio selectionapproach is the problem of estimating return moments, in particular return expectations. We analyzethe consequences of using return estimates implied by analysts’ dividend forecasts under the...

In the literature, implied rates of return are suggested as estimators for future expected oneperiodreturns because of their property not being prone to the discount rate effect. The discount rateeffect describes the problem that changes in expected future one-period returns lead to...
