The results of by using GARCH (1,1) indicate that the NFFF variable is the most important determinant for JCI. This is based on observations testing various variations of the GARCH model, the t-test value of NFFF is always higher than the KURS. This finding confirms that the IDX is still driven by foreign investors.
