彭博：国家队上周借道9只ETF净流入1287亿元，为2025年4月关税战抛售以来最大单周买入，周一创业板指仍收跌逾1%
这是对上周已发生资金流的事后统计报道，非新增买入承诺；A股周一完整交易日已在护盘预期下运行完毕，结果是沪指仅微涨0.19%、创业板指与深成指跌超1%、成交缩量超3400亿元、超3100股下跌，说明1287亿元护盘未能扭转负螺旋——连报道正文都引述分析师称干预不足以反转。直接载体（宽基/创业板ETF）A股已收盘无可执行窗口，美股中概ETF盘前无工具报价且隔夜高开风险大。无明确受益个股，方向（政策托底偏多 vs 市场仍在下坠偏空）相互对冲，不具备正期望edge。

不做 华泰柏瑞沪深300ETF（510300.SH）
事后资金流数据（上周1287亿元）非新增催化，A股周一已收盘且当日盘面显示护盘未稳（创业板跌超1%、缩量普跌），无可执行窗口且edge不足；ETF无行情工具报价。
不做 iShares中国大盘ETF（FXI）（FXI.US）
美股盘前不可成交、无工具核验真实盘前价；消息为上周旧数据，隔夜高开易成卖点，且周一A股成长股走弱，风险收益不对称。

结论摘要
彭博确认国家队上周1287亿元护盘为2025年4月以来最大，但属事后资金流数据；周一A股在该背景下创业板仍跌逾1%、缩量普跌，托底未确认反转，且A股已收盘、美股ETF无可靠报价，不做。

消息传播链
- 彭博首发汇编数据：9只国家队ETF上周净流入1287亿元，为2025年4月以来最大；发布时点北京为周一午间，A股当日已完整交易。市场反应:周一A股收盘沪指+0.19%、创业板指/深成指跌超1%，成交1.61万亿缩量3475亿，超3100股下跌
关键理由
- 若国家队本周延续同等强度买入，宽基ETF有政策托底支撑，上周五尾盘放量转涨显示干预对短期情绪有边际效果
- 1287亿元规模与2025年4月危机级别相当，代表政策底信号，历史上该级别干预后通常有阶段性反弹窗口
主要风险
- 正文明确引述分析师与投资者警告此类干预不足以扭转负螺旋，周一创业板再跌逾1%、缩量3475亿元已初步验证该担忧
- 买入数据为上周（10/19-10/23）历史流量，本周力度未知，若国家队停手则托底预期落空，追买者接盘
反向证据
先例如何影响了这次决策
对本次决策的影响:先例缺位结合当前事件内的冲高回落证据，压低置信度并支持AVOID，而非据名义规模追多。
方向:未构建可用先例面板：本次为宏观资金流事后报道，缺少同市场、同相位（护盘数据公布时点）且锚点为一手首发的对齐样本；2025年4月干预仅在正文中作为背景出现，无独立首发日期与时刻可锚定。
涨幅量级:不足，无法用先例校准幅度
形态:正文自身提供的最近一个样本（上周五干预→创业板+4.2%→周一再跌超1%）已显示托底反弹持续性弱，但这是当前事件内观察而非外部先例。

China’s state-led funds stepped into the market with the heaviest buying since the April 2025 rout, as authorities ramped up efforts to stem a market freefall.
Inflows into nine exchange-traded funds known to be actively traded by the national team reached 128.7 billion yuan ($19 billion) last week, according to data compiled by Bloomberg. That’s the most since the nearly 140 billion yuan recorded during April 2025, when US President Donald Trump’s trade war battered markets and Beijing took a slew of actions to prop up investor sentiment.
Analysts and investors had earlier warned that such intervention would be insufficient to reverse the negative spiral, but signs are emerging that the buying is helping ease the decline. Chinese stocks swung into gains late Friday as turnover in a basket of ETFs favored by the national team picked up pace.
The ChiNext Index jumped 4.2% on Friday, snapping a nine-session losing streak. The tech-heavy gauge pared an early loss of as much as 3.1% on Monday to trade 1.7% lower as of the mid-day break.
