Deep Dive
Why did the stock market rebound on January 7, 2025?
The stock market rebounded due to a combination of factors, including restrictions on institutional selling, a surge in AI-related sectors, and increased trading volume. The Shanghai Composite Index rose by 0.71%, the Shenzhen Component Index by 1.14%, and the ChiNext Index by 0.70%. The rebound was also supported by strong performances in sectors like computing power, hardware, and data center power equipment.
What were the key sectors driving the market rebound?
The key sectors driving the rebound were computing power, hardware, and AI-related industries. Specifically, sectors like copper cable high-speed connections, data center power, CPO, and semiconductors saw significant gains. Additionally, sectors such as hydrogen energy, nuclear power, and data center cooling towers also performed well, driven by increased demand for electricity due to AI advancements.
How did ByteDance's plans for a self-built data center substation impact the market?
ByteDance's announcement of plans to build its own data center substation boosted the market, particularly in the HVDC (high-voltage direct current) sector. This move signaled ByteDance's intention to gain greater control over its power supply, leading to a surge in related stocks like Shunna Co., Ltd., Zhongheng Electric, and Wan Kong Intelligent Manufacturing. The substation project is in the early stages of IDC construction, similar to the role of copper cables and optical modules in AI server production cycles.
What role did nuclear power play in the market rebound?
Nuclear power played a significant role in the rebound, driven by AI's increasing demand for electricity. OpenAI CEO Sam Altman's announcement about Helion's potential demonstration of net energy gain nuclear fusion further boosted the sector. Stocks like Xiongtao Co., Ltd. (3 consecutive涨停), Haioo Co., Ltd. (2 consecutive涨停), and others in the nuclear power and data center cooling sectors saw strong gains. Additionally, tech giants like Microsoft, Amazon, and Google are investing heavily in nuclear power, further supporting the sector's growth.
How did the competition between TikTok and WeChat impact the market?
The competition between TikTok and WeChat, particularly in the e-commerce space, stimulated market activity. TikTok introduced its largest-ever merchant support plan, including measures like waiving commissions and offering promotional fee rebates. WeChat also expanded its gifting feature and launched a private domain incentive plan. This competition led to a rebound in related stocks, with high-profile stocks like Mengjie Co., Ltd. and Yuanlong Yatu Co., Ltd. seeing significant gains. The IP economy also rebounded, with stocks like Meibang Apparel and Shifeng Culture performing well.
What were the key trends in institutional and retail investor activity on January 7, 2025?
Institutional and retail investor activity was marked by significant movements in the computing power and hardware sectors. Top investors like Chen Xiaoqun, Ge Laoda, and Zhang Mengzhu were active, with Chen Xiaoqun opening new positions in Maige Mite and Ge Laoda focusing on financial technology. Institutional investors also showed strong interest in stocks like Huijin Technology and Guoxing Optoelectronics, while selling off positions in stocks like Welan Lithium and Hewang Electric. The overall market saw increased activity from both institutional and retail investors, with a focus on AI-related sectors.

大家好,今天是 2025 年 1 月 7 日星期二,欢迎来到 A 股作业帮。昨天说限制机构卖出,今天如期反弹了,是不是 GJD 出手了,感觉自己又行了?其实就是个反弹,先看 3280 点。接下去从 K 线、量能、板块、个股这四个方面做数据复盘。
几乎均以光投阳线报收。
微盘股更是大涨近 4%量能护市两市全天成交额 1.08 万亿较上个交易日放量 180 亿两市成交依靠午后的一波放量才得以维持 1 万亿以上北向资金成交总额 1609.48 亿元南向资金净买额 129.04 亿港元
其中户股通成交总额 712.75 亿元,深股通成交总额 896.73 亿元。板块、三立和端侧硬件为首的 Fan AI 方向全线爆发、铜缆高速连接、数据中心电源、CPU、半导体等板块涨幅居前,大消费、机器人等超跌方向快速轮动、流感、中药、医药商业、创新药等板块跌幅居前。
各股方面,今日共 92 股涨停,联板股总数 16 支,19 股封板未遂,封板率为 83%,两市超白股涨超 10%。尽管联板股晋级率仍仅有 33%,但昨日上演低天板的美邦股份成功实现 4 进 5。昨日放量长阴断板的顺纳股份以低天板形式展开缩量反包,从而带动部分高位人气股尝试展开反核修复。
顺纳股份的低天板反包,也继续刺激数据中心电源设备领涨算力硬件股,进而将强度扩散至铜蓝与光模块等算力硬件端中的传统高热度方向。与此同时,零售概念人气股中百集团尽管盘中多次尝试开板修复,但最终仍收出连续第三个跌停,对整个大消费板块的修复力度形成压制。
随着 FAN、AI 等前期热点板块的大面积修复,近期避险资金主导下的抗流感等医药板块,出现冲高回落与指数在线悄悄板态势,也反映市场整体风偏偏好,出现积极转暖迹象。焦点板块及个股近日,字节跳动采购不信息发布平台,发布自建数据中心变电站设计框架采购巡言公告。
构建自建变电站的计划,意味着字节跳动希望在电力供应上实现更大的自主权和可控性。
直接受益数据中心变电站建设的 HVDC 高压直流数电方向继续强势领涨人气股舍纳股份走出地天板中恒电器三变科技万控制造等多股涨停进而带动阿富斯电源 BBU 电池 BMS 等细分全面发散电站设备等采购处于 IDC 土建的前期阶段与铜缆光模块等在 AI 服务器生产周期的地位类似
此外,随着英伟达 GB300 有望于今年二季度发布,作为新增部分的超级电容器以及增量环节的 MPO、高密度光纤连接器、大尺寸 HDI 等细分也走出一波像样的领涨行情。在算力硬件端完成无差别普涨修复后并不利于次日增量资金的承接,一些此前滞涨的增量逻辑环节反而容易走出独立行情。
OpenAI CEO Sam Altman 透露,他预计其投资的公司 Helion 将很快掩饰技能量增益核聚变。青盟以及核电板块延续强势的同时,可控核聚变概念午后大面积爆发。青盟叠加数据中心 OPS 电池的熊涛股份路德三联版,核电叠加数据中心冷却塔的海鸥股份二联版,九升电器,荣发核电,宏讯科技等大批个股午后上板。
除去 OpenAI 外,微软、亚马逊、谷歌等科技巨头纷纷加码压住核电。而国内方面,2024 年新核准的 5 个核电项目中,民营企业参股比例也首次提升至 10%。因此本轮核电的发展与背后 AI 对电力的渴求密切相关,一些有数据中心和算力题材叠加的品种,在板块内仍具备更高辨识度。
据雷鸟创新微信公众号消息,雷鸟 V3i 拍摄眼镜 1 月 7 日即将发布。Ai 眼镜概念在昨日完成大面积补贴后表现继续分化,此前四联版的比翼股份尽管短暂开板翻滑,
但最终仍封死跌停,不过中科蓝讯、博士演进、卓伊科技等大面积展开向样修复。英伟达 CEO 黄仁勋在 CIS 演讲中,不仅如期发布了最新一代的电脑 GPU GeForce RTX50 系列,
还带来了关于 AI 模型、智能驾驶、AI 机器人、AI 超级计算机等众多惊喜。刺激午后英伟达产业链以及相关的机器视觉等展开异动,东方金工、红博股份双双涨停,和林威那等多股纷纷为居涨幅前列,而今日芯片股的整体性反弹也得益于算力以及端侧硬件的双重加持。
韩 5G 总市值突破 3000 亿序创历史新高,但其尾盘加速不排除存在部分踏空资金回补动作。1 月 6 日,抖音电商退出史上力度最大的商家扶持计划,共包含免佣金、反推广费、社帮扶基金等 9 条措施。
此前微信送礼物功能逐步扩大测试范围,同时微信小店推出四月激励计划。抖音和微信间的电商大战打响,刺激相关概念股展开修复。高位人气股孟杰股份反包涨停走出五天四板,元龙雅图、利欧股份、里南股份等多股涨停。
除去抖音电商以及微信小店外,IP 经济概念也结束,此前低迷展开一波凌厉的超跌反弹,美邦服饰反包涨停走出四天三板,十凤文化、广白股份也双双涨停,随着东北集团、中北集团等高位人弃股,遭遇 A 纱的零售板块形成压制。
作为大消费概念中的新经济细分 IP 文创、微信送礼以及此前一度热炒的首发经济等方向,在此前完成充分调整后,会有望重回资金视野。
资金复盘 1.央行今日进行 71 亿元 7 天 7 逆回购操作中标利率为 1.50%与此前持平因今日有 1577 亿元 7 天 7 逆回购到期实现金回笼 1506 亿元 2.杠杆资金截至 1 月 6 日两融合计 18307 亿元较前一交易日减少 82 亿元

当天机构净卖出前三的股票分别是何旺电气、蔚蓝理星、威士顿,净流出金额分别是 6523 万元、6019 万元、4564 万元。4、顶级油资,陈小群买入麦格米特 9200 万卖出 5700 万。
葛老大,买入惠金科技 7600 万,买入麦格米特 6100 万卖出 2700 万。张盟主,买入杰华特 6000 万,买入中百集团 3600 万卖出 1400 万,买入国光电器 2300 万。肖贤派,买入泰晨光 6100 万,买入东阳光 4000 万,卖出中百集团,亚视光电,动力源,鲁康医药。
方新霞,买入利欧股份 6600 万,卖出一道信息,止损国新光电亏了 1000 多万。佛山,买入的国新光电两亿亏 15%,还在锁仓中,买入的一亿鲁康医药也在锁仓,买入友好集团 3800 万,卖出利欧股份。5. 建平
今天的龙湖榜有进步,陈小群,葛老大,张盟主,肖贤派,方心霞都是上榜一人级别,上榜的游资数量也有所增多。今天的看点,陈小群新开仓了麦格米特,这回手法有变化,玩起来了出底仓。佛山的两亿国星光殿,一亿的鲁康医药都没出,这是手法变了,还是被限制卖出了?
陈小群,葛老大,肖贤派主要做算力,方新霞,是做超跌,葛老大有做互联网金融。好了,今天就到这里了。祝大家早日富可敌国,迎娶白富美,牵手高富帅,走向人生巅峰。我会一直陪着大家,因为陪伴是最长情的告白。
