KARACHI The Karachi stock market closed slightly lower on Wednesday as the buyers remained cautious throughout the trading session amid increased public sector borrowing, grim law and order situation in the city and uncertainty about the release of next IMF tranche of $ 3.2 billion. The KSE-100 share index shed 10.37 points or 0.08 per cent to close at 12,433.17 points against previous days close of 12,443.54 points. The KSE 30-index fell by 20.72 points to close at 11,865.06 points and KSE all share index shed 7.46 points to close at 8,614.42 points. The market turnover marginally decreased to 83.25 million shares compared to 88.11 million shares of Tuesday. Ahsan Mehanti, Director at Arif Habib Investment Limited, said that bearish activity was witnessed in the earnings announcement session at KSE on institutional profit-taking. Renewed foreign interest in oil sector, recovery in global commodities and capital markets, rising local power tariff, higher local fuel and urea prices provided support in selected scrips, he said. Hasnain Asghar Ali, a senior analyst, said that early hiccups and technical adjustment in various main board stocks led to a mixed-to-negative opening. Corporate influx on dips in high yielding stocks mainly from the fertilizer sector neutralized the negative impact due to sell-off in singled out stocks from energy and petroleum sector, while targeted and syndicated support, and high quantum change of hands on strength in cement sector. He further said cement sector, despite increase in input cost and decline in local and export sales, reported decent turnover besides providing the day traders short term trading opportunity, thus keeping the snap rallies led activity alive through out the session.
