TSE's main index, the market cap-weighted TEDPIX, fell 0.9% for the day under mounting selloff pressure in blue chips.
Its equal-weighted index gained close to 0.2%, as small-sized listed companies, especially pharma, agro and tire companies, performed comparably better.
Bruising selloff in large caps is best shown in a 1.5% decline in TSE-30 Index, which tracks the performance of top TSE-listed companies.
Prices in 65% of listed companies at both TSE and the junior equity market Iran Fara Bourse dropped on Tuesday, comprising 319 tickers, according to Eghtesad News website.
The asymmetrical daily price spread set in favor of the market’s positive side prevented TEDPIX from further collapse.
Share prices spread asymmetrically from -2% to +6% per day instead of the previous ±5% since the beginning of trading week on Saturday.
