This paper assesses the role of correlation dynamics in mean-variance sector allocation. A correlation timing framework is deployed to evaluate dynamic strategies against a static constant covariance strategy and the nonparametric RiskMetrics covariance model. We find using sector portfolios in...

This paper assesses the economic value of modeling conditional correlations for mean–variance portfolio optimization. Using sector returns in three major markets we show that the predictability of models describing empirical regularities in correlations such as time-variation, asymmetry and...

This study uses the VAR-BEKK methodology to examine the relationship between equity returns and currency exposure for a sample of U.S., U.K. and Japanese banks and insurance firms during 2003–2011. The findings indicate that banks' equity returns are negatively related to changes in foreign...

The article explores the relationship between short-term interest rates and the equity returns of the UK financial services industry. Based on the arbitrage pricing theory, the present study seeks to answer the sensitivity and pricing questions. The former is tested with a linear two-index model...
