韩国KOSPI因AI芯片股抛售盘中暴跌逾7%，三星跌7.7%、SK海力士跌8.8%，亚太芯片股普跌
这是一条对已经发生的盘中系统性板块抛售的事后行情报道，不含新增的、可定位到单一公司的基本面催化；韩国/日本市场正在交易，7%–9%的跌幅在信号到达时已大体兑现。追空是在单日极端超跌后追弱、面临尾盘反弹与SIDECAR熔断后的均值回归风险；抄底则没有任何正向surprise。多空两侧均无正期望edge。

不做 三星电子（005930.KS）
盘中已跌7.7%的板块beta式抛售，无个股新增利空；追空追在7%级超跌与熔断之后、面临反弹，抄底无正向催化，多空均无edge
不做 SK海力士（000660.KS）
跌幅8.8%已盘中兑现且为AI情绪/中国竞争驱动，非个股砍单或指引下修；不满足明确强空催化，亦无做多依据
不做 东京电子（8035.JP）
仅为AI资本开支情绪联动下跌6.6%，无自身订单或基本面事件，做空属追弱、不满足做空红线
不做 软银集团（9984.JP）
作为OpenAI投资方因行业融资担忧跌8%，无公司层面新事实，纯主题联动不构成可交易催化

结论摘要
隔夜美股芯片下跌叠加AI融资/中国竞争担忧，引发亚洲开盘半导体板块系统性抛售，KOSPI盘中暴跌7.4%。这是情绪与仓位驱动的板块beta，跌幅已基本兑现且无个股新催化，追空风险高、抄底无依据，故不做。
消息传播链
- AP发自香港的行情稿，描述亚洲开盘芯片股抛售、KOSPI盘中跌7.4%，属于对正在发生行情的报道而非事件首发
- 归因于中国芯片竞争及路透所称英伟达对华AI加速器出货同比降44%，确认抛售为多因素行业情绪，非单一公司事件
关键理由
- 信号本质是对既成盘中暴跌的新闻复述（KOSPI -7.4%、海力士 -8.8%），并非带来增量信息的一手事件
- 韩日市场仍在交易、跌幅已大体实现，A股/港股午后外溢幅度不可预测，缺乏可定位、有时效edge的交易载体
主要风险
- 若后续曝出具体公司级利空（如海力士/三星砍单、业绩下修），则板块beta可能转为个股强空催化，需重判
- 单日7%–9%暴跌叠加SIDECAR熔断，追空极易遭遇短线技术反弹或政策护盘，做空盈亏比差

先例如何影响了这次决策
对本次决策的影响:先例不足且事件无增量事实，支持回避而非追空或抄底。
方向:无可直接对齐的、由单一公司事件锚定的先例；本条为宏观/行业盘中行情报道，不适用企业事件先例面板。
涨幅量级:缺乏同市场同相位、以一手事件为锚的先例来校准幅度，且跌幅已盘中兑现，不据此设定止盈止损。
形态:无证据可用；单日系统性超跌后既有延续也有反弹，方向不稳定。
