The Saudi Arabian bourse ended 0.10% lower at 6,317.67 points due to weak performing real estate developers and insurance firms. In a rare event in Riyadh, Sabic (up 0.85% at SR89.00) was not the most liquid stock but the newly listed Knowledge Economic City (KEC). On its first day of trading, KEC ended at SR10.30, following its Sr1bn ($272m) IPO from May at SR10 per share. The Madinah-based KEC aims to be the core education centre in Saudi Arabia. Its total investment upon completion is SR30bn ($8bn).
