The Doha-based QE Index reached 8,496.25 on Tuesday. Shares of Qatar Telecom (Qtel) belonged to the driving forces behind the index surge, as Qtel closed 3.08% higher at QR144. Qatar National Bank (QNB) added half a percent to close at QR138. Capital Intelligence (CI), the international credit rating agency, today announced that it has raised QNB’s Financial Strength Rating (FSR) to ‘AA-’ from ‘A+’, as AMEinfo.com reported earlier in the day. The ratings action follows continuous improvement in the Bank’s overall performance and financial condition, as these are reflected by the Bank’s very strong credit metrics. The Bank’s Long-Term and Short-Term Foreign Currency Ratings are affirmed at the same level as the Sovereign Ratings of ‘AA-’ and ‘A1+’, respectively. Al Khaleej Takaful declined 1.11%, ending at QR44.65.
