Cover Story: Variance and correlation matrices contain a multi-dimensional array of numbers, representing all the information about individual variabilities and pairwise covariabilities; however, it is difficult to interpret them in a concise way. We propose a scalar measure of summarizing the volatilities and correlations in the variance (or correlation) matrix into a single number, which is desirable for easy interpretation of the overall variance (or correlation) in the multivariate system. The scalar measures can be useful tools in many research areas of economics. They can be applied to the issue of regional market comovements during the financial crisis, and they can also be practical tools for fund managers to produce clear measurements of portfolio diversification effects and risk. View this paper
