Hong Kong equities surged on Wednesday after the BoJ announced stimulus measures to boost faltering economy. However, continuous uncertainty whether Spain will ask for financial aid capped the upswing of the Hong Kong blue chips. The Hang Seng Index rallied 1.17% to end the session at 20,841.91. Six out of nine business sectors included in the index surged. The largest gains posted telecommunication and oil and gas companies, advancing by 2.24% and 1.58%. China Mobile and China Unicom Hong Kong spiked 2.22% and 2.34% while CNOOC and PetroChina climbed 1.12% and 2.71%. Lenders also moved higher, with Construction Bank of China and Industrial and Commercial Bank of China rising 2.51% and 2.48%. At the same time, consumer services pushed the index lower, with Sands China tumbling 2.19%.
