The main gauge of Tehran Stock Exchange, TEDPIX, lost 25,679 points or 1.88% for the day to end trade at 1,336,778.
The TSE-30 Index logged a bigger loss giving up 2.3%. The index tracks the performance of top 30 TSE-listed companies in terms of market cap.
Large caps, including petrochemical, mineral, steel and metal producers, are very sensitive to forex rates. Steep decline in currency prices on Sunday weakened the sentiment of shareholders of these export-based companies simply because lower exchange rates harm their margins.
Giving a better picture of small caps, the TSE’s equal-weighted index was down 1.66%.
About 4.96 billion shares valued at 29.4 trillion rials ($105 million) changed hands at TSE on Sunday. Leasing Khodro Ghadir Company was the biggest winner as its shares went up 4.93% to 8,300 rials per share.
Sepanta Communication Development Company incurred the biggest loss among all TSE-listed companies and went down 4.97% to 465,370 rials per share.
Persian Gulf Petrochemical Industries Company contributed the most to the benchmark's fall, followed by Mobarakeh Steel Company, Parsian Oil and Gas Development Group Company and National Iranian Copper Industries Company.
