For the problem of continuous time optimal portfolio selection, we found that the optimal strategies for investors with different performance criterions can be constructed using a limited number of fixed processes (mutual funds), for a incomplete market with a larger number of available risky...

Unknown model parameters, like expected returns, cannot be accurately estimated from short samples. Respective estimation error most likely leads to the portfolio, inconsistent with its target risk/return profile. We investigate the ways of reducing the impact of estimation error on portfolio...

This thesis investigates models of market risk assessment based on genetic algorithms, with specific reference to asset portfolio choice under volatile market conditions. It does so by developing computational simulations of asset portfolios, which are then subjected to stressful price events. A...

This paper investigates the impact of using different risk-adjusted measures of performance on the evaluation of UK investment trusts. Significant negative skewness is probably the most important empirical property of the time series of returns under analysis. Performance results based on the...

This paper focuses on the attitude of non-professional investors towards financial losses and their decisions on wealth allocation, and how these change subject to behavioral factors. Our contribution concerns the integration of behavioral elements into the classic portfolio optimization....

We show that preferred investment styles can be determined by the big five personality traits. Using this result, we build a tool that recommends investment styles. The resulting recommendations are significantly higher rated than random recommendations.We collected detailed personality traits...

We fill a gap in the proof of a (rather critical) lemma, Lemma B.1, in Jin and Zhou (Mathematical Finance, Vol. 18 (2008), pp. 385–426). We also correct a couple of other minor errors in the same paper

In choosing a glide path strategy for asset allocation over their working lives, retirement savers face a tradeoff between the higher expected wealth provided by strategies that maintain or increase equity holdings over time, against the greater potential security offered from shifting into more...

A line of recent studies cast doubt on the efficacy of the lifecycle investment strategy, which calls for switching into a more conservative investment portfolio as retirement approaches, as a suitable way to provide for the retirement needs of workers with defined-contribution pensions. After...
