刘纪鹏教授针砭的两个问题：大股东减持和量化交易，大家都很拥护，但本ID只拥护他的第一个议 题。 2. 善于归纳，对成长趋势股的节奏把握更加精准； 这两个优点，可能意味着大A将告别草莽时代，和西方股市的发展历程契合。 量化在短期策略和反应速度上有人类无法比拟的优势，但在中长期策略上，目前来看，人类或者半人码 更加擅长。 所以，本ID是拥护量化的。个人投机者，如果缺乏认知和长期的训练，亏损是大概率的，现在如此， 以前也是如此，和量化其实无关。 从当下的市场表现看，量化交易有两个优点： 1. 速度上抑制游资对垃圾股的炒作； ...

来源：市场资讯 （来源：大公馆） 源自：睿知睿见 11月最后一周，科技板块大幅反弹，行情能持续吗？ 1. 成交额 本周成交额缩量到1.7万亿左右。周五是1.6万亿。 距离地量的1.5万亿还差一些。 2. 换手率 中证全指的换手率下降到1.75%左右，周五是1.72%，距离1.5%还差一些。 3. 波动率 回顾一下本周的行情：从一级行业来看，本周上涨最多分别是通信8.7%；电子6.05%；传媒4.23%。 而表现不好的是偏红利的石油石化，煤炭，交运和银行。 很明显，本周是科技大幅反弹！但市场调整不会一蹴而就！所以还是要保持耐心。 一、指标跟踪 我们先看看一些数据指标处于调整的什么阶段。 波动率下降的速度比较快，今天已经达到15.68。 随着波动率的下降，市场的轮动会明显加速，追涨杀跌很容易连续亏损。因为这个时候是量化掌握主动 权。频繁操作很容易被量化收割。 市场往往会维持较长时间的低波状态才会开启下一轮行情。 4. 两融买入额占比 本周在10%左右震荡。 虽然有所下降，但距离情绪低点还有距离。 5. TMT成交额占比 当下仍然没有有效降低到30%以下。 正所谓多头不死，空头不止。 这种拥挤度，短期内不大容易再次 ...

一、健康科技独角兽的资本盛宴 11月28日那天，我正盯着量化系统里跳动的数据流，突然弹窗跳出轻松健康通过港交所聆讯的消息。这家注册用户1.684亿的数字健康巨头，用54.9% 的年复合增长率向市场展示着什么叫"科技+保险"的黄金赛道。作为见证过无数IPO的量化交易者，我却注意到一个有趣现象：每当这类明星企业上 市，普通投资者的账户往往与市场热度形成诡异反差。 记得2025年上半年，某医疗AI企业上市首日暴涨47%，但同期调查显示78%的散户投资者在这波行情中收益率不足5%。这种割裂感让我想起自己十 年前初入市场时的困惑——明明利好消息铺天盖地，为什么实际操作起来总是差之毫厘？ 二、4000点牛市里的冰冷数据 上证指数突破4000点那天，我的朋友圈被各种庆祝刷屏。但量化系统给出的数据却呈现另一个故事：4月7日至10月30日期间，虽然指数上涨19.6%， 但仅有40%个股跑赢大盘。更值得玩味的是，4200只上涨个股中超过4000只振幅大于30%，这意味着大多数投资者其实是在过山车行情中反复被收 割。 这让我想起行为金融学中的"处置效应"——投资者总是过早卖出盈利股票而过久持有亏损股票。在量化视角下，这种现象的本质 ...

引子 最近金融圈最热闹的话题，莫过于美联储12月议息会议。作为全球资本市场的风向标，鲍威尔的一举一动 都牵动着亿万投资者的神经。但有趣的是，就在市场热议降息概率从40%飙升至80%之际，A股却上演着 一场场惊心动魄的"机构暗战"。作为一名量化交易的老兵，我发现这两件事背后竟藏着惊人的相似之处 ——都是大资金在主导游戏规则。 看着美联储内部愈演愈烈的分歧，我仿佛看到了A股市场的翻版。纽约联储主席威廉姆斯和旧金山联储主 席戴利这些鸽派代表，像极了A股里那些总想"抢跑"的游资；而鹰派官员的担忧，又像极了坐庄主力对跟 风盘的忌惮。 鲍威尔面临的两难选择，恰似我们每天在股市里遇到的灵魂拷问：是该追涨还是该观望？是相信技术面还 是基本面？这种纠结我在2025年那波行情中深有体会——当时上证指数三个月涨了15%，但真正能吃到肉 的散户却寥寥无几。 二、大资金时代的生存法则 记得去年跟踪过一只股票，从5月底的6元涨到8月底的9元，50%的涨幅看似诱人。但用传统技术分析看它 的走势图，简直能把人逼疯——五波说大不大的调整，三番五次的冲高回落。当时很多朋友都在第三次调 整时被洗出局，结果错失了后面30%的涨幅。 一、美联储的困局 ...
