Abstract: In this talk we will discuss how the top eigenvalue/eigenvector pair evolves through time for estimators of covariance and correlation matrices of equity return type data. By this we mean that the matrices have a top eigenvalue which is well separated from the others. Our main results are that both the eigenvalue and eigenvector of a correlation matrix has an extra stability effect,...
