KARACHI- The KSE-100 index hardly managed to close in positive zone on Friday amid intensified operation against militants and limited activity by retail and institutional investors. Benchmark index added 4 points on the last trading day of the week with limited volume of just over 100m shares. Expectation of positive review announcements by MSCI Barra on Pakistan index status next week played a key role in positive closing. However, uncertainty largely affected the market sentiment in the backdrop of PM call for strong action against militants of Swat and Malakand. Cautious investors continued to remain on the sideline keeping in view the permission granted to Pak Army to eliminate Taliban from their roots. The sluggish behaviour of the market resulted in distracted investors as the investors at the market already book considerable losses in 2008, said research analyst Bilal Asif. The KSE-100 share index started the day in the red zone. Benchmark index touched days highest level of 7,196.73 points and sustained the positive note in the end at 7,129.51 points, adding just 3.85 points.
