Commercial loan interest and US dollar were determined as the control variable. Johansen-Juselius cointegration test, Granger causality test and variance decomposition tests were used in this study. According to the results of the analysis, there was a long-term relationship between the BIST 100 index yield and foreign portfolio investments, but there was no Granger causality among the variables. In the variance decomposition test, it was determined that the effect of foreign portfolio investments on BIST 100 index return was only less than the effect of the effect of exchange rate on the effect of foreign portfolio investments.},author={Nevin ÖZER},year={2018},journal={The Journal of Social Sciences}}
