However, negative values resulting from the transformation may obscure the interpretation of the analysis. This novel study aims to investigate the effects of non-negative dimension reduction methods on the mean-variance portfolio optimization model. Backtesting results for major stock market indices show that reducing dimensionality of asset prices may improve the overall efficiency of the mean-variance portfolio optimization output.
