Karachi Stock Exchange (KSE), after the index 'floor', appeared trading positively, yet the overall business activity doesn't seem to be picking up, as it remained lackluster even today. The market opened on a positive note, but the persistent political uncertainty in the country and the wait-and-see attitude of the investors in view of the impending presidential election contributed a great deal towards restraining the market to a highly cautious trading. KSE-100 index at close of business today making a nominal gain by 10 points wrapped up at 9239.
