HONG KONG (Nikkei Markets) -- Asian stocks outside of Japan retreated as an overnight slide on Wall Street and drop in global oil prices overshadowed MSCI's decision to include China's domestic shares in its global indexes.
The Nikkei Asia300 Index of 316 influential companies lost 0.5%. Singaporean and South Korean shares paced the region's losses, while the Hang Seng Index slid 0.6% by the midday break in Hong Kong. Going the other way, the CSI 300 Index of large companies listed in Shanghai and Shenzhen added 0.5% after MSCI said late Tuesday in New York it will add 222 yuan-denominated A-shares to its MSCI Emerging Markets Index, whose constituents had a capitalization of $4.6 trillion as of May 31.
