The large caps rally pushed up the main gauge of Tehran Stock Exchange, TEDPIX, by 0.5%. The market cap-weighted index gained 5,866.17 points on Sunday to end trade at 1,175,590.
Penny stocks were lukewarm as seen in the subtle 0.02% rise in TSE's equal-weighted index, which gives the same weight to all shares regardless of their market cap.
Top gainers were stocks in refinery, petrochemicals, metal and technical engineering companies while almost all other share categories dropped.
Blue chips were buoyed up largely by demand from institutional traders. Fixed income funds reportedly are among the buyers as they were obliged last week to allocate a bigger portion of their portfolio to stocks by the end of current calendar month on March 20.
Despite the slight increase in TSE's benchmark, liquidity continued to flow out the market for 16 sessions in row with net capital outflow rising 21% compared with the previous session to reach 8.4 trillion rials ($18 million), according to Eghtesad News website.
