This article documents the stochastic properties of bivariate returns to international stock market indices. In particular, the article searches for the best fit among a class of higher-order VARMA(u,v)-EGARCH(p,q) models with normal errors and a constant conditional correlation using MSCI...

Long memory is found in the conditional volatilities of financial returns measured at daily or higher frequencies, as well as in residual cross-products in bivariate series. We test for long memory in conditional correlations by extending the fractionally integrated GARCH model to include...

One of the consequences of the Capital Asset Pricing Model (CAPM) is that the expected excess return of a financial instrument is proportional to the expected excess market return. The proportionality constant, called the instrument's beta, is the coefficient in the linear least-squares fit of...

We investigate the impact of shrinkage estimation techniques for the moments of asset returns on risk-parity portfolios …. In contrast to mean-variance portfolios, the risk contributions of individual assets in risk-parity portfolios are fixed … a priori. This additional restriction stabilizes empirical portfolio weights in time. We show that the marginal risk …
