早盘气氛转淡，午后大反转！ 今天早上，A50盘中突然直线杀跌，由涨转跌，恒指、恒生科技指数也是双双转跌。从结构上看，银行股继续 成了空头主力，银行板块早盘一度杀跌近2%，厦门银行跌近4%，青农商行、西安银行、渝农商行等多股跌逾 1%。银行股杀跌也带动了红利指数和大盘权重指数的下行。然而，临近午盘时，中字头突然发力。午后，中 国交建率先涨停，并带动权重指数走强。 然而，临近午盘时分，中字头突然发力。午后，中国交建直线封板，中铁装配飙升逾14%，中国中铁、中国建 筑等快速上扬。这些个股的突然表现，带动A50及A股指数大反攻。 红利指数下午的反弹，煤炭股的贡献度很大。午后，山西焦煤、潞安环能、山煤国际等集体涨停。与此同时， 市场上也流传着一份国家能源局综合司发布的《关于组织开展煤矿生产情况核查促进煤炭供应平稳有序的通 知》，这份通知的内容可能是刺激煤炭大反攻的主要原因。 那么，究竟发生了什么？从消息面上来看，仍有一些积极因素催化。比如欧洲理事会主席科斯塔、欧盟委员会 主席冯德莱恩将于7月24日来华，参加纪念建交50周年的中欧峰会。美国财长表示，会尽快与中国进行谈判 等。从盘面上看，市场的涨跌存在明显的结构性特征。 ...
