This paper provides a review of the methods for measuring portfolio performance and the evidence on the performance of professionally managed investment portfolios. Traditional performance measures, strongly influenced by the Capital Asset Pricing Model of Sharpe (1964), were developed prior to 1990. We discuss some of the properties and important problems associated with these measures. We the...

Alternative investments have proved their worth.

And yet, standard risk-adjusted performance indicators often prove unsuitable for hedge funds, which rely on highly specific tec...

It was hypothesized that involuntary psychiatric admission patterns from the Sharpe Hospital catchment area do not have a direct correlation with county population.

Unlike previous research, the general case where differential information leads to the problem of "forecasting the forecasts of others" and to non-trivial dynamics of higher order expectations is studied. In particular, it is proved that the model...
