KARACHI: Falling oil prices, thanks to the resumption of energy shipping via the Strait of Hormuz following the signing of the ‘Islamabad MoU’, continued to fuel peace optimism, triggering buying interest across multiple sectors. As a result, the benchmark KSE-100 index maintained its recovery for the fourth straight session on Thursday. Topline Securities Ltd said the Pakistan Stock Exchange (PSX) witnessed another bout of bullish momentum, with investors maintaining a positive stance throughout the session.
