• 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.
