新华财经北京12月18日电 （胡晨曦）A股三大指数12月18日涨跌不一，沪指早间低开，随后震荡回升； 创业板指全天低位调整。沪深两市成交额1.66万亿，较上一个交易日缩量1557亿。盘面上，AI医疗概念 集体走强，华人健康、塞力医疗等涨停；银行板块震荡拉升，上海银行涨超3%；零售概念走强，中央 商场、上海九百涨停；商业航天全线爆发，盛洋科技、天箭科技等涨停。下跌方面，锂电池板块回落， 海科新源、华盛锂电大跌；算力硬件股下挫，生益科技、景旺电子等跌超5%。 截至收盘，沪指报3876.37点，涨幅0.16%，成交7049亿元；深证成指报13053.97点，跌幅1.29%，成交 9506亿元；创业板指报3107.06点，跌幅2.17%，成交4499亿元。 中指研究院：预计未来5年全国城镇住房需求总量约为49.8亿平方米 热点板块 盘面上，医药商业、银行、军工电子、无人零售、IP经济、啤酒等板块和概念股涨幅居前；元件、电 池、汽车整车、海南自贸区、可控核聚变、PCB等板块和概念股跌幅居前。 机构观点 巨丰投顾：周四市场震荡运行，医药商业板块涨幅居前。"十五五"的开局之年经济环境整体良好，预计 2026年国内经济"三驾 ...

其次 ，从热点看，半导体芯片等科技股高位震荡，通信、算力硬件、CPO板块等周三表现活跃，聚集市场人气，对大盘反弹起到引领作用。同时保 险、券商等大金融板块也有走强，显示市场风格以价值和成长双轮驱动。当然，由于成交量较低，热点总体以震荡反复、消化蓄势为主，期待年底过后， 随着流动性回流，展开新一轮上升走势。 首先 ，从全天走势看，下午1点半之前，大盘呈现牛皮盘整态势，围绕周二收盘指数窄幅整理，小盘股走势偏弱。下午1点半后，随着大金融、算力 硬件、有色金属等板块走强，两地股指走出一波强劲上升走势，收盘阶段则强势盘整，最终以全天次高位报收。结合近期市场表现，虽然受年末资金面制 约，大盘成交量一直维持在2万亿元以下，难以发动全面放量走强的上攻行情，但市场也表现出较强韧性，以震荡整理作为年底行情的过渡。从目前看， 短线仍以中性偏强为主，12月下旬后随着为明年投资布局的意愿增强，大盘有望出现"翘尾"行情。 展望后市 ：大盘继续震荡整理，以稳为主。关注盘中热点和量能匹配情况。 风险提示 ：消息面或海外市场表现超预期，流动性的不确定性。 ...
