绿城中国（03900）今日盘中大跌7.12%，引发市场广泛关注。此次股价下跌主要源于公司高层领导的重大变动。
根据绿城中国发布的公告，公司董事会主席发生变更。原执行董事兼董事会主席张亚东因工作安排辞任，由刘成云接任非执行董事和新任主席。同时，周长江辞去执行董事职务，但将继续担任公司执行总裁。这些高层变动可能引发了投资者对公司未来发展方向的不确定性，从而导致股价下跌。
值得注意的是，绿城中国的股票在此次人事变动公告后曾短暂停牌，并于今日上午9时恢复交易。市场对这一突然的领导层变动反应强烈，导致股价开盘后迅速下跌。分析人士指出，新任主席刘成云的背景和未来发展策略将成为投资者关注的焦点，公司需要尽快稳定市场情绪，明确未来发展方向，以重新获得投资者的信心。
