The Pakistan Stock Exchange (PSX) experienced a significant downturn during the week ending February 13, 2026, with the KSE-100 index plummeting by 4,526 points, or 2.46%, to close at 179,604 points. This decline was primarily driven by weak corporate earnings and investor concerns over the Reko Diq mining project, as well as rising political and security tensions, according to Tribune Latest. The market began the week with a sharp drop of 1,789 points and continued to face volatility, with a notable rebound on Wednesday before further losses on Thursday and Friday. Arif Habib Limited (AHL) noted that the index's bearish trend was exacerbated by disappointing earnings results and high volatility, with major sectors like banking, oil and gas, and technology contributing negatively to the index.
