Testing the transmission of price fluctuations of physical assets to selected industries (Application of state space approach and ARDL model)

The purpose of this study is to test the transmission of price fluctuations of physical assets to the returns of selected industries including the chemical, pharmaceutical, food, construction and basic metals industries. For this purpose, the data of selected industries return index, dollar rate, Bahar Azadi coin price (representative of gold market), Iranian crude oil price and housing price from mid-December 2008 to March 2019 were prepared with daily frequency and using conditional heterogeneity variance method and state space approach and Kalman filter, conditional standard deviation of returns is considered as a measure of fluctuations. Then, using the ARDL method, how the fluctuations in the price of physical assets are transmitted to the index of returns of selected industries is described. The results show that the chemical industry from the fluctuations of the foreign exchange market, housing and gold, the pharmaceutical industry from the fluctuations of the oil, foreign exchange and housing markets, the construction materials industry from the fluctuations of the foreign exchange market, the food industry from the fluctuations of the oil market and the basic metals industry from the market fluctuations gold has a contagious linear system that provides evidence of information inefficiency in the Tehran Stock Exchange industry.
