KARACHI:
Pakistan stocks dropped for a second consecutive day on Friday with investors concerned about the possibility of the US Congress imposing more conditions on American assistance and trade with Pakistan, analysts said.
The Karachi Stock Exchange benchmark 100-share index ended 1.32 per cent, or 189.7 points, lower at 14,230.49 points, with a volume of 195.7 million, compared to Thursdays close of 14,420.19 points.
The news of possible strict conditions on American aid to Pakistan kept the mood at the market negative, said Atif Zafar, a research analyst at the JS Global financial services company.
The US House Appropriations Subcommittee for State and Foreign Operations on Thursday approved a bill that would attach additional conditions to any civilian or military aid to Pakistan by demanding it help more in combating militant groups and disrupting networks providing material for homemade bombs being used against NATO forces in Afghanistan.
