This study adopted the unit root test, Granger causality test, vector autoregression model. The empirical results indicated that Apple-related concept stocks were partially related to one another; however, the movement of these stocks was not consistent. Furthermore, the Taiwan Electronics Sector Index was not easily affected by other individual stocks, but affected other individual stocks substantially. The results obtained in this study can be used by people who intend to invest in Apple-related concept stocks as a reference for determining their investment strategies and stock choices
