The role of stock exchange is so crucial in the investment market. Since the accepted companies in the stock exchange make this process active, it is fundamental to investigate their functions and status and select the best option for the investment. In the present study the best method to rank the accepted companies in the stock exchange of the extraction industry has been applied. At the first step the elitism method has been used to select the most effective indexes to compare the above mentioned companies. Theses selected indexes include: ROA, the ratio of debts to properties as a leveraging ratio, the ratio of sale to asset, currencies, and P/E. At the second step, the companies engaged in this industry are ranked through “Fuzzy Topsis” method, based on the elites’ comments and by having an overview on the literature review of the mentioned ratios. The findings of the previous studies show that the first ranking belongs to the mineral and industrial company of “Chader Melo” with “Kachad” trade mark.
