Karachi: Prevalent uncertainty on falling crude price resulted in the KSE-100 Index taking a plunge on Monday, shedding 536 points or 1.09% to end at 48,655.72.

Falling crude prices in the international market took their toll on the index-heavy oil and gas sector amid dull trading with cumulative volume dipping to 133 million shares compared with Friday’s tally of 182 million.
