This study investigates the effects of the market portfolio being unknown on the estimation of beta in the CAPM. Providing an analysis of the impact of using a proxy for the market portfolio when the market portfolio is known. This allows one to ask and answer 'if what' questions, such as if...

In the paper the exponential risk measure of Damant and Satchell is used to formulate an investor's utility function and the properties of this function are investigated. The utility function is calibrated for a typical UK investor who would hold different proportions of equity. It is found...

This paper presents information on institutional investorsí and investment consultantsí attitudes towards and their performance assumptions for the alternative asset classes, property, and the mainstream markets. It also gives estimates of UK institutional exposures to these asset classes....

We examine a simple measure of portfolio performance based on prospect theory, which captures not only risk and return but also reflects differential aversion to upside and downside risk. The measure we propose is a ratio of gains to losses, with the gains and losses weighted (if desired) to...

We study the question of which asset pricing factors should be included in linear factor asset pricing model. We develop a simple multivariate extension of a Bayesian variable selection procedure from the statistics literature to estimate posterior probabilities of asset pricing factors using...

This paper investigates the presence of momentum return when priced for common components. Using a sample period from 1926 through 2005 for all stocks listed in the NYSE, AMEX and NASDAQ we show significant momentum return remains both at the portfolio level and at the individual stock level. We...

This paper investigates the contribution of common components and stock specific components in generating momentum return. Using a decomposition approach in a multi-dimensional framework we report that momentum return resulted from all stocks listed in the NYSE, AMEX and NASDAQ from 1926 through...

In this study I show that Fama and French's (1992) conclusion that betas do not explain the cross-section of asset returns may be due to a few implementation methods used for their tests. First, I show that post-formation portfolio returns tend to be much higher than market portfolio returns,...

The role of selling (or marketing) period uncertainty in understanding risk associated with property investment is examined in this paper. Using an approach developed by Lin and Vandell [2001, 2005] and Lin [2004], combined with a statistical model of UK commercial property transactions, we show...
