Although the pharmaceutical industry is not one of the largest industries in the country in terms of market volume, but with about 39 companies active in the stock market has always been one of the industries of interest to investors. The total market value of this industry is about 133 thousand billion tomans and in this regard is among the middle industries. One of the characteristics of the pharmaceutical industry is the high competition between companies. The number of initial supply of pharmaceutical materials and products has increased in recent years, which indicates the widespread success of major actors in this field in the capital market. Pricing of pharmaceutical products is usually done by the government and with the interaction between the Ministry of Health, insurance companies and companies active in this industry. In recent years, the start of drug exports by some companies and the resulting foreign exchange earnings have attracted much attention to the pharmaceutical group.
