KARACHI: The Pakistan Stock Exchange (PSX) ended lower on Friday, in line with a bearish trend across most Asian markets, snapping a four-session winning streak as investors resorted to panic selling ahead of the weekend amid renewed tensions in the Middle East and rising oil prices. According to Topline Securities, the market remained under pressure after overnight tensions between the US and Iran near the Strait of Hormuz fuelled concerns about the stability of the fragile ceasefire and prospects for a lasting peace agreement. The benchmark KSE-100 index fell 1.03 per cent, or 1,777 points, to close at 171,115.82.
