The Impact of OPEC Oil Price Fluctuations on Different Industry Groups in the Seasonally More Active Companies on the Tehran Stock Exchange

In this study, we use the world oil price index to assess the impact of OPEC oil price volatility on companies included on the list of the fifty most active stocks on the Tehran Stock Exchange. We use a linear model with twenty dependent variables to measure the impact of oil price fluctuations, as the independent variable, for the period 2010 to 2016. We notice that rising oil prices are associated with increasing share of groups such as multi-family housing construction, real estate, chemicals, investment funds and conglomerates while declining prices are associated with increasing share of  companies active in pharmaceuticals and metal products. It is therefore useful for the Tehran Stock Exchange to reflect the values of OPEC oil index on its website.
