China's main stock index surged 1.54 percent in heavy trade on Wednesday, hitting a new all-time high, as yuan strength boosted the property sector and positive local media reports about the share market buoyed sentiment. The Shanghai Composite Index reached an intra-day high of 4,175.444 points before ending at 4,173.709, bringing its rise this year to 56 percent.
Gainers outnumbered losers by 704 to 133 with over 35 shares jumping their 10 percent daily limits. Turnover in Shanghai A shares was large at 213.0 billion yuan ($27.8 billion), though down from Tuesday's 223.6 billion yuan.
Zhou Lin, analyst at Huatai Securities, said investors continued to believe authorities would permit a continued uptrend in the market, and that any official attempts to cool it would not produce a big pull-back. On Wednesday, positive newspaper reports encouraged buying. The official China Securities Journal reported that from start of this year to May 21, around 1,083 A shares - 78 percent of the total in Shanghai and Shenzhen - had doubled.
