Karachi: Pakistan's benchmark stock index closed unchanged as emergency trading limits continued for the sixth day to halt a slide in shares that has dragged the gauge down by almost a third this year.

The Karachi Stock Exchange 100 index rose 0.11 point to close at 9,239.26. Seventy-three of the benchmark index's 100 constit-uents were unchanged yesterday.

"Investors remain on the sidelines and the situation will continue like this at least until Tuesday'' when officials meet to discuss the curbs, said Farhan Rizvi, an economist at JS Global Capital.

"The board of the exchange will meet after trading hours on Sept. 9,'' Shehzad Chamdia, a board member of the Karachi Stock Exchange said.

"I hope by then the situation will clear up and the market will have some stability. We will decide then whether to keep the limits.''

Shell Pakistan, the second-biggest fuel supplier in Pakistan, fell 2.6 per cent to Rs422.45.

Pakistan State Oil Ltd. the nation's biggest fuel retailer, fell 0.4 per cent to Rs279.99.
