Bulls tightened their grip on the Pakistan Stock Exchange (PSX) on Monday, with the benchmark KSE-100 Index soaring to an intraday high of 1,622 points before settling 1,547 points higher at a record 146,929, up 1.06%.

According to a Topline Securities report, market sentiment surged after reports emerged that US firms were preparing to invest in Pakistan’s energy sector. This optimism was further reinforced by better-than-expected corporate earnings, adding to the upbeat tone.

Heavyweights MARI, BAHL, OGDC, MEBL, and MCB spearheaded the rally, collectively contributing 959 points to the index’s advance.

Trading activity remained vibrant, with 607 million shares changing hands and a traded value of Rs43.95 billion. LOTCHEM topped the volumes chart with 73 million shares traded.

Ahsan Mehanti of Arif Habib Corp said that strong financial results, coupled with speculation over the positive outcome of US investments under the Pak-US trade deal, pushed stocks to new all-time highs.

“Record $3.2 billion remittances in July 2025, rupee stability, and expectations of an export surge due to the India-US tariff conflict acted as catalysts for the record bullish close at the PSX,” he added.
