This study aims to forecast Portfolio VaR using Noise-reduced Correlation Matrix based on Denoising Autoencoders, which helps anticipate extreme losses in the future. The dataset comprises the US stocks with daily adjusted closing prices. The portfolio weights for each asset were calculated by applying the Risk Parity method to the entire asset group using the Noise-reduced Correlation Matrix. Forecasting VaR through Delta-Normal, Historical, GARCH, and Denoising Autoencoders methods, and subsequently conducted Backtest VaR. Empirical analysis revealed that DAE-GARCH-VaR (Student’s T Distribution) exhibited a significant noise reduction effect on the correlation matrix and the superior performance.
