This paper establishes general conditions for the validity of mutual fund separation and the equilibrium CAPM. We use partial preference orders that display weak form mean preserving spread (w-MPS) risk aversion in the sense of Ma (2011). We derive this result without imposing any distributional...

This paper analyses the properties of two popular portfolio strategies. They are the Buy and Hold strategy and the Discretely Rebalanced strategy. It is assumed that the underlying stocks have a multivariate lognormal distribution. The distribution of the sum of correlated lognormals plays a...
