What is Covariance Cleaning in Minimum Variance Portfolios about?
The document discusses the impact of covariance cleaning techniques on minimum variance portfolios. It introduces shrinkage techniques and random matrix theory cleaning as advanced statistical tools to improve the estimation of covariance matrices compared to simple empirical estimation. It then builds minimum variance portfolios using different covariance estimation methods and compares their realized volatility to assess whether the cleaning techniques can reduce estimation errors and improve portfolio co
