本周各家券商策略分析师讨论的焦点在于是否持股过节，整体偏向乐观。 华西策略李立峰团队也指出，可稳步备战节后"红包"行情。 其复盘2017-2025年，万得全A春节后10个交易日平均涨幅3.3%，春节前10个交易日平均跌幅-1.3%，多数年份节后表现优于节 前。从胜率角度看，近九年万得全A春节后5个交易日、春节后10个交易日胜率分别为78%、78%，相较春节前胜率有明显抬升； 行业层面，31个申万一级行业中28个节后胜率高于节前，TMT指数在春节后5个交易日、10个交易日的胜率分别为89%、100%， 相比节前有明显提升，指向科技板块通常在节后阶段表现较好，弹性更足。 银河策略杨超团队称，A股市场上行动能仍较强，春节后上涨概率或大幅提升，"持币"虽可锁定确定性收益，但极有可能部分失 去节后上涨带来的超额收益。以2016年至2025年间历 史规律看，春节前，资金偏好向高股息、消费、防御板块集中，大盘风格表现占优，随着春节将至，A股市场逐步修复回暖，或 出现"节前躁动"；春节后，A股市场上涨概率较大，资金转向小盘风格，周期风格和成长风格表现更优。 广发策略刘晨明团队指出，目前4000点左右的位置，占据天时地利人和。 ...

据上证报2月5日报道，美国数据中心建设热潮引发用电荒，天然气被视为最佳解决方案。全球能源监测 机构的全球油气工厂追踪数据显示，截至2026年1月，美国在建天然气发电装机容量超过29GW，一年 内翻了一番还多。不过这其中许多项目可能几年内都无法开工，主要就是因为制造商缺乏可用的燃气轮 机。GEVernova首席执行官指出，2025年该公司的燃气轮机合同量增长了约80%，然而大部分在过去两 年内签订的高利润订单需要到2027年以后才能开始交付。 西南证券认为，从燃气轮机头部厂商来看，GEV，西门子能源，三菱重工订单加速提升，在手订单排 期已达4-5年，后续将持续扩大产能。GEV原计划于2026Q3实现燃机年产能20GW，现已前移至2026H1 完成目标，并进一步上调扩产计划至2028年24GW。为支撑产能上调，GEV预计于2025年-2028年持续 投入100亿美元资本开支。国内主机厂，成撬商，零部件厂商有望受益于本轮AI数据中心建设驱动的电 力需求上行周期。 公司方面，据上证报表示， 杰瑞股份：公司是国内油气装备龙头企业，钻完井业务，天然气业务，燃气轮机发电机组业务在国内外 市场均实现突破。 联德股份：公司深度 ...
