The dimensionality reduction of nonstationary stock market price was performed by using generalized dynamic principal component (GDPC), adapting Brillinger dynamic principal component (BDPC) concept based on the reconstruction of the stock market price. The results shows that GDPC have a higher percentage of explained variance percentage (above 90%) and lower mean squared error among the other methods. Thus, this shows that a direct application may also achieved better result performance.
