Dynamic Principal Component Analysis of Multivariate Volatility via Fourier Analysis
AbstractA method is proposed to compute a time-varying correlation matrix between asset prices. The method has a natural geometric interpretation in terms of dynamic principal components analysis. The paper illustrates, via Monte Carlo experiments and data analysis, the potential of the method in computing cross-correlations; and it describes market integration, introducing the concept of reference asset.
