摘要

This study proposes a novel way to improve investors' total return rate of portfolio optimization by de-noising the data using Ensemble Empirical Mode Decomposition (EEMD). Firstly, the authors briefly introduce risk measure theory and EEMD methodology. Then, empirically demonstrating that the de-noising technique using EEMD surely has some efficient impact on the portfolio, and the cumulative return rate of the portfolio when the objective function is CVaR with the data de-noised 3 Intrinsic Mode Functions (IMFs) is the highest one. It indicates that the impact of de-noising the data using EEMD is much more significant on the portfolio when the objective functions have less powerful risk discrimination, and vice versa.
