HONG KONG (MarketWatch) -- Mainland Chinese shares suffered their worst decline in more than a year on Friday, as fear of aggressive rate hikes and the impact of the U.S. dollar's rise triggered a sell-off across sectors. But Macquarie strategist Michael Kurtz says the fall was unlikely to be the beginning of a bear market, given strong liquidity conditions. The Shanghai Composite Index SHCOMP, -0.19% tumbled 5.2% to 2,985.43, its worst percentage fall in more than a year, while the Shenzhen Composite Index sank 6.1% to 1,296.95. Shares of Yunnan Tin Co. 000960, -0.89% , China Southern Airlines Co. ZNH, +0.62% 600029, -0.51% and Cosco Shipping Co. 600428, -2.99% fell by or close to the day's 10% limit, while SAIC Motor Corp. 600104, and Jiangxi Copper Co. JIXAY, +37.28% 600362, -0.56% fell nearly 9%.
