The benchmark of Tehran Stock Exchange, TEDPIX, surged 3.5% on Tuesday, gaining 56,972 points to end trading session at 1,664,559 points.
The rally swept through all small and large cap stocks with large-caps dominant as shown in the 4.2% growth in the TSE-30 index, which tracks the performance of 30 largest companies listed with the TSE in terms of market capitalization.
Tuesday also showed renewed investor interest in small companies with 1.23% growth in the equal-weighted index.
Stocks rally was driven by a combination of factors, namely measures adopted by the regulator to boost demand and spillover effect from parallel markets, namely currency and gold.
During the market downturn, which wiped off 30% of the TSE value, foreign exchange rates soared to historic highs well over two months, absorbing a portion of the capital flight from the share market.
Rise in forex rates gave further rise to inflation expectation and obviously boosted profit margins for giant listed companies involved in the export business.
On Tuesday, about 9.43 billion shares valued at 110.16 trillion rials ($408.03 million) changed hands at TSE.
