The Qatar Exchange (QE) 20 Index declined by 0.34 per cent to 12,520.36 points on Tuesday, June 17. A lack of catalysts left the sector indices mixed when the closing bell rang in Doha. The first lender Qatar National Bank closed flat at QAR177.20. Ooredoo dived 4.90 per cent to QAR136. The share has been under selling pressure since the start of the week, after radical ISIL insurgents seized Iraq’s northernmost city. Ooredoo runs telecom operations in Iraq.
