Pakistan's Karachi Stock Exchange (KSE) bucked a three-day bearish trend on Wednesday as Washington made the much-needed payment to Pakistan under Coalition Support Fund (CSF) while bullish sentiments in regional markets following strong Chinese data also helped improve the sentiments. The benchmark KSE 100-Index jumped 1.66 percent, or 436.86 points, to 26,677.27 points Wednesday, as against 26,240.41 points reported Tuesday.
