The Pakistan Stock Exchange (PSX) experienced a sharp downturn on Thursday, February 19, 2026, as the benchmark KSE-100 index plunged nearly 4% amid heightened geopolitical uncertainty. The index opened lower and faced sustained selling pressure throughout the session, with only brief minor recoveries that failed to hold.
It reached an intra-day low of around 171,647 points before closing at 172,170.29, down 6,682.80 points or 3.74% from the previous close.
This marked a significant reversal after a strong rebound the day before, when the index had climbed to 178,853 points on value-hunting and institutional buying.
Geopolitical Tensions and Oil Price Surge Weigh Heavy
Analysts pointed to escalating US-Iran tensions as a primary driver of investor caution. Rising international oil prices, supported by these regional risks, further eroded confidence in energy-sensitive sectors. Both foreign and local investors turned risk-averse, leading to broad-based selling.
Head of Research at Ismail Iqbal Securities, Saad Hanif, noted that the combination of geopolitical jitters and oil price spikes kept sentiment subdued, with no strong bullish momentum emerging.
Sector-Wide Impact and Key Performers
Heavy selling hit major sectors including cement, commercial banks, fertilizers, oil and gas exploration, oil marketing companies (OMCs), power generation, and refineries. Index-heavy stocks such as OGDC, PPL, PSO, HUBCO, MARI, MCB, and MEBL traded deep in the red, dragging the benchmark lower.
Despite the overall bearish trend, some smaller stocks showed resilience, with gainers like Azgard Nine (up 12.5%) and others in niche segments posting double-digit rises. High-volume trading was seen in stocks like WorldCall Telecom and K-Electric.
The drop reflects broader market vulnerability to external shocks, even as Asian markets elsewhere rose on tech gains. Investors remain watchful for any easing in geopolitical risks or positive domestic cues to support a potential recovery.
