证券研究报告 2025年07月27日 请务必阅读正文之后的信息披露和免责申明 1 摘要 周思考：房地产指数的长期超额与销量增速和房价增速的趋势性变化相关。短期来看，近一年房地产指数超额收益呈现脉冲式锯齿形态，具有周期短、波动剧烈、与 政策强关联三大特征。我们认为，这一现象是因为近期地产股表现主要受短期刺激政策博弈驱动，而基本面复苏较弱则难以支撑行情持续性。具体来看，近6轮上涨波 段中指数超额收益均值达13%，平均持续18天。我们认为，短期来看，若7月政治局会议或相关部委政策释放更积极的房地产刺激信号，地产指数或开启新一轮脉冲式 上行；中长期视角下，当前商品房销量与房价跌幅已现收窄趋势，但指数仍处低位，待基本面止跌回稳态势进一步明确确认后，板块有望迎来持续性行情。 市场回顾：本周（7.14-7.18），全A上涨1.86%，市场继续上攻。板块方面，机器人、稀土相关概念表现强势。当周全A日均成交额达15397亿元，较前周增加466亿元， 市场活跃度高位震荡。市场情绪方面，当周平均上涨家数为2779家，较前周减少275家；平均涨停家数由前周的68家减至61家，赚钱效应有所减弱。资金流向方面， 策略报告：投资策略专题 ...
