Karachi Stock Exchange (KSE) investors this week also kept waiting on the sidelines for the much needed support fund, which saw the trading dull and dreary. KSE-100 index this week closed without any change at 9183 points. The investors were seen cautious and playing safe due to the extension in the index 'floor' until November and the non-availability of support fund. Average turnover this week as compared to the previous one increasing by 24 percent worked out to 1,88,000 shares. Even the financial results of the banks and oil marketing companies this week could not energize the lifeless market trend. Analysts forecast this dull and dreary trading trend persisting until the injection of the support fund in the market.
