The main gauge of TSE, TEDPIX, lost about 12,000 points at the early hours of trading session before clawing back to positive territory later, Financial Tribune reported.
The early collapse was a visible reaction by jittery investors to a decision by Financial Action Task Force, the global anti-money laundering watchdog, to place Iran on its blacklist.
The short-lived jitters soon give way to optimism about future hike in share prices emanating from rising currency rates on Saturday.
TEDPIX closed the session 0.65% higher to reach 481,869.64 points. The equal-weighted index closed higher at 1%. The index gives the same weight to all stocks irrespective of their market caps.
FATF blacklisted Iran on Friday after Tehran failed to comply with international anti-terrorism funding norms.
