This paper evaluates the impact of oil prices on the industry and the total index of the Tehran Stock Exchange. In addition, the
impact of oil shocks on the Tehran Stock Exchange is also studied. The analyzed data are the weekly crude oil price data in the
industry and the index of the Tehran Stock Exchange during the 10-year period from 2005 to 2015. For data analysis, this paper
proposes an appropriate mathematical model based on the non-parametric technique of data envelopment analysis (DEA),
which is a powerful mathematical tool for ranking decision-making units (DMUs). Ultimately, we used the proposed model to
calculate the efficiency and ranking of 10 companies active in the food and beverage industry (except for the sugar group) and
analyzed the results with the CCR model. Following that, the final ranking was done using the weighted average method.
According to the results of the research, Mahram Production Group Company was ranked 1st in the weighted average method,
and Shir Pegah West Azerbaijan was ranked second, and Nab Industrial Companies, Pars Livestock Feed, Georgian Biscuits,
Iran Behnoosh, Pak Dairy, Behpak, Salemeen and Shir Pegah Isfahan ranked 3rd to 10th
, respectively.
