倒车接人还是进入调整阶段？ 港股市场午后亦明显走弱。港股午后随A股跌幅扩大，恒生指数一度跌超400点。恒生科技指数回吐逾2%涨势转跌0.5%，AI、机器人、半导体行业冲高回落。 昨晚，美联储降息，但外围大宗商品集体大幅回落，美元指数亦反弹至97上方。分析人士认为，这可能是一次博弈美联储降息之后的兑现操作。从人民币走势来 看，虽然美元指数大幅反弹，但人民币贬值力度并不大。中国8月Swift人民币在全球支付中占比2.93%，前值2.88%。 从杀跌结构来看，红利板块大幅走弱，可能是市场杀跌主因。午后，金融科技全线走弱，加大了市场回调压力。成份股中荣科科技、银之杰、指南针、同花顺、财 富趋势等皆出现大跌行情。 消息面上，反而有利好消息传出。德国万亿欧元资产管理机构DWS首席执行官Stefan Hoops日前透露，今年10月将于欧洲推出跟踪中证A500指数的ETF，为海外投 资者提供布局中国资产的新工具，届时DWS或成为全球首家推出跟踪中证A500指数的ETF的海外机构。 今日（9月18日）午后，A股突然回调。上证指数、创业板指盘中双双跌超1%，机器人、半导体产业链大幅回落，有色行业跌幅进一步扩大，场内上涨个股 降至 ...
