JEDDAH – Saudi stocks closed lower Saturday, dragged down by losses in petrochemical and banking sectors. The benchmark Tadawul All Share Index ended 0.93 percent lower at 6,774.26 points and the petrochemical index ended 0.8 percent lower at 5,964 points. The Saudi market is "slightly down because of the reduced growth rates in the US," Turki Fadaak, head of research at Albilad Investment Co. in Riyadh, said Saturday. Fed officials lowered their forecasts for US economic growth and raised their predictions for unemployment in each of the next three years. Policy makers now see 1.9 percent to 2.4 percent growth in 2012, down from their April forecast of 2.4 percent to 2.9 percent. Stocks "are clearly responding to downward pressure in oil," Jarmo Kotilaine, chief economist at National Commercial Bank, said. "The oil price is something that fuels the fiscal engine and the broader economic mood." Petrochemical giant Saudi Basic Industries Corp. (Sabic) closed 0.5 percent down. The banking index slipped 0.9 percent to 15,417 points, dragged down by losses in heavyweight Al Rajhi Bank which fell 0.7 percent.
