A Portfolio Approach to Estimating the Average Correlation Coefficient for the Constant Correlation Model
AbstractThis paper presents a portfolio approach to estimating the average correlation coefficient of a group of stocks that are considered for portfolio analysis. The average correlation coefficient has been shown to produce a better estimate of the future correlation matrix than individual pairwise correlations. The advantage of the approach described here is that it does not require the estimation of pairwise correlations for estimating their average. Copyright 1989 by American Finance Association.
