We propose an econometric model to decompose corporate bond spreads into compensation required by investors for unpredictable future changes in the credit environment and for expected default losses. We use the model to understand whether the significant reduction in corporate bond spreads...

This paper reviews the main dimensions underlying the selection of a classical portfolio performance measure, namely the Sharpe Ratio, Jensen's alpha, the Modified Jensen's alpha, the Treynor Ratio, and the Information Ratio.

This study explores whether conditional correlations between precious metals and stock markets impact upon expected returns on precious metals. The empirical evidence presents that there is no significant trade–off between conditional correlations and expected returns. This study reveals that...

My recent book, Econophysics and Capital Asset Pricing: Splitting the Atom of Systematic Risk, splits beta, the capital asset pricing model's basic unit of systematic risk, into subatomic (or “baryonic”) components, by analogy to the Standard Model of particle physics. This essay offers...

This essay seeks to rehabilitate the capital asset pricing model by splitting beta, the basic unit of systematic risk, into subatomic (or “baryonic”) components. By analogy to quantum chromodynamics and other aspects of the Standard Model of particle physics, this essay bifurcates beta on...
