Investor sentiment was weighed down by state-owned enterprises' (SOE) losses, coupled with weak oil and global equities, with caution compounded by worries over a potential US government shutdown and tariff risks

"Weak global crude oil prices and weak global equities amid fears over the outcome of the US Govt shutdown, US tariffs played a catalyst role in bearish activity at PSX,” he added.
