Real estate developer Dar Al Arkan jumped 2.8 percent and was the most traded stock, while Emaar Economic City climbed 2.2 percent. Top lender National Commercial Bank surged 4.2 percent. Local and regional investors are accumulating Saudi equities as the kingdom prepares to allow direct foreign share ownership in the first half of 2015. Savola Group stabilized, falling 1.1 percent.
