Abstract

The stock market is one of the most prominent examples of financial markets, which has always attracted economists’ attentions in terms of understanding its nature, the mode of its performance, and factors affecting it. Meanwhile, the foreign exchange market can be considered as a competitor for the stock market and, depending on the export or import-based nature of the economy, may affect the country and the stock market differently. Empirical research has indicated positive and negative effects of the exchange rate on stock price index. Therefore, considering the significance of this issue, the aim of this study was to analyze the asymmetric effects of the exchange rate on stock price index in the period of 2001/1-2017/3using seasonal data for Iran's economy. To this end, the nonlinear autoregressive distributed lag (NARDL) model was estimated and the effects of exchange rate, interest rate, real liquidity and consumer price index on the stock price index were investigated. The results show that the decrease in the exchange rate has a positive and significant effect on the stock price index in the short and long-run, but the increase in the exchange rate in both periods has not significant effect on the stock market. Therefore, the exchange rate has an asymmetric effect on the stock price index.
