Last year, the Karachi Stock Exchange had shed over 4500 points and faced many black days as former Prime Minister and his allies allegedly made it rise and fall for personal gains. It was said in those days that people plundered billions of rupees in this scandal. The KSE collapsed thousands of points this year too. The question arises which forces are behind the KSE crash this time? -HIRA BUKHARI, Lahore via e-mail July 23.
