The KSE-100 closed the week at 175,329, down 2,368 points or 1.33%. Three of five sessions finished lower, and the damage was concentrated: Monday, Tuesday and Wednesday took 2,920 points out of the index between them.
Two things did it. Oil rose almost 3% on Monday as tension escalated around the Strait of Hormuz, with Brent back above $90 - unwelcome for a net importer. Then Tuesday's inflation print came in at 11.15% for August, up from 9.2% in July, and banks and cement led the market lower. By Wednesday the index had broken below 175,000, with 356 stocks falling against 113 rising.
Refineries were the exception, bid up ahead of expected plant upgrade agreements - Attock Refinery gained 8.44% and the sector rose 8.61% on Monday alone.
Thursday and Friday recovered 552 points as a global rally lifted sentiment. The index is still 21.7% above its 52-week low and 8.2% below July's record close. The IMF's fourth review is the next scheduled test.
