We present a geometric approach to discrete time multiperiod mean variance portfolio opti-mization that largely simplifies the mathematical analysis and the economic interpretation of such model settings. We show that multiperiod mean variance optimal policies can be decom-posed in an orthogonal...

Despite the enormous growth of the asset management industry during the pastdecades, little is known so far about the asset pricing implications of investmentintermediaries. Investment objectives of professional asset managers such as mutualfunds differ from those of private households. However,...

We find that stocks exhibiting high dispersion in analysts’ earnings forecasts do not onlyunderperform in the U.S. but also in many European countries. Testing for the dispersioneffect in many countries calls for adequate multiple testing controls and we show that theU.S. dispersion effect...
