TEHRAN, August 19 (NIPNA) – Basic metals overtook chemical products to become the largest industry on Iran’s stock market in the first month of summer, with the three biggest sectors accounting for more than half of total market value, according to data from Iran’s Securities and Exchange Organization.

At the end of Tir, the equivalent of July 22, the basic metals sector had a market value of 3,426 trillion tomans, followed closely by chemical products at 3,402 trillion tomans and petroleum products at 1,784 trillion tomans, according to the organization’s Economic Analysis and Risk Department.

The ranking marked a shift from the previous month and the end of the previous Iranian calendar year. Chemical products had ranked first at the end of Khordad and Esfand 1404, while basic metals and petroleum products held second and third place, respectively.

Iran’s listed companies operate across 48 industries on the Tehran Stock Exchange and Iran’s over-the-counter market. The 10 largest industries had a combined market value of more than 14,257 trillion tomans at the end of Tir.

Those 10 sectors represented 84.5% of the total value of Iran’s stock market, down 0.8 percentage point from the previous month. Their share stood at 85.3% at the end of Khordad and 84.9% at the end of Esfand 1404.

The latest figures underscore the continued dominance of commodity-linked industries—including metals, chemicals and petroleum products—in Iran’s equity market, with changes in sector valuations capable of quickly reshaping the ranking of the market’s largest industries.
