Using high-frequency data, we decompose the time-varying beta for stocks into beta for continuous systematic risk and beta for discontinuous systematic risk. Estimated discontinuous betas for S&P500 constituents between 2003 and 2011 generally exceed the corresponding continuous betas. We...

We evaluate the impact of extreme market shifts on equity portfolios and study the difference in negative and positive reactions to market jumps with implications for portfolio risk management. Employing high-frequency data for the constituents of the S&P500 index over the period 2 January 2003...

This study evaluated the relationship between inflation and infrastructure sector stock returns in emerging markets in the long and short run. It employed a panel autoregressive distributed lag (PARDL) model applying the mean group (MG), pooled mean group (PMG) and dynamic fixed effects (DFE)...

In Cascon and Shadwick (2006) we extensively discussed the use of models in finance. We pointed out how ideas that have become generally accepted often depend on assumptions that, as time passes, are likely to be unstated or even forgotten entirely, with potentially significant consequences. In...

We provide first empirical evidence of the long-term realized performance of alternative beta strategies. Despite diversified risk premia portfolios achieving satisfactory Sharpe ratios of 0.80 – 1.07 over the past decade, we show that up to two thirds of the performance can be explained by...

Beta has been a controversial measure of risk ever since it was proposed almost half a century ago, and we do not pretend to settle with this article what decades of research has not. We do, however, take advantage of the recent trend of investing in countries and industries through index funds...
