Genetic algorithms (GAs) are appropriate when investors have the objective of obtaining mean.variance (VaR) efficient frontier as minimising VaR leads to non.convex and non.differential risk.return optimisation problems. However GAs are a time.consuming optimisation technique. In this paper, we...

The rise in popularity of benchmark free and complex trading strategies throughout the last decade has made available a large variety of risk and performance profiles. As a consequence, to account for their complex performance characteristics, a lot of effort has been devoted to classify and...

This multi-faceted analysis of institutional investment defines fiduciary finance institutions as the third pillar of the financial system, alongside banks and insurers. It documents the role played by investment funds and the money management industry during the recent financial crisis, and...

For many years, the cross-sectional Survey of Consumer Finances (SCF) has shown relatively weak or inconsistent changes in the shape of the distribution of net worth, despite many shifts in income and other economic factors. In 2009, households that had taken part in the 2007 SCF were...

The aim of this paper is to show the expected utility theory over time and its evolution onto what is now known as the risk aversion theory. This paper also highlights the importance of the link between the relative risk aversion and the selection of an optimum investment portfolio (Relative...
