For this goal, two short and long-term regimes created and MV-GARCH model and, BEKK solution used for the daily data from 21 March 2001 to 22 December 2014. The results showed that in the short and long run, the oil shocks have negative effects on the Stock Exchange. In addition, the impact of oil price volatility on the Stock Exchange is negative in the long-run. Due to the fact that in the short run oil price volatility has a positive effect on the oil price index, this effect has led to fluctuations in the stock index.
