Abstract

Iran Stock Exchange is the most important component of Iran capital market and more attention has been paid to it in recent years. Many factors affect the Iran stock exchange. In this paper, the effects of oil price and gold price on stock market index are investigated and a three regime Markov Switching Vector Error Correction model is used to examine the nonlinear properties model during the period January 2003 to December 2014. The results of the study shows that the relationships between variables can be analyzed in three different status, so that the three regimes, respectively, represents the “great depression”, “mild depression” and “expansion” period. The results of the model show that the impact of oil price on stock returns is negative and significant in all three regimes; this means that with rising oil price, stock market returns are reduced. But the relationship between gold price and stock market returns varies during the period, according to market conditions. It means that positive shock inflicted on the price of gold in the short-run (10 months) leads to reduce the stock returns and in the medium-term and long-run, it leads to increase the stock returns.
