▼ 亏 -2.71%入场 07-14 盘后首笔 @69.57 → 离场 07-15 常规开盘 @67.90
日 K 取自复盘打分切片 · 蓝点/蓝虚线 = 纸面入场价 · 灰虚线 = 纸面离场 · 持有期红底 = 赚(价格在入场线上方)、绿底 = 亏
💡 交易逻辑MidCap纳入带来被动买盘，盘前未充分反应
怎么买 限价买入 不高于 71.73、仅下一个交易日，不成交作废
怎么卖 止盈 +3%(半仓)/+6%(清仓) · 止损 -3% · 时间止损 2日
不做 Karman Holdings（KRMN.US）
虽有SmallCap 600纳入利好，但标的近13周持续下行、近5日跌10.96%，指数层级和资金强度较弱，做多edge不足，不做。
不做 Chart Industries（GTLS.US）
GTLS删除源于BKR收购即将完成，股价已按并购对价锚定，指数删除不是新的同向交易催化，不做。

消息传播链
- S&P Dow Jones正式宣布BTSG调入S&P MidCap 400、KRMN调入S&P SmallCap 600，2026-07-17开盘前生效。市场反应:公告发布在美股盘后；行情工具显示BTSG 7月14日收69.67美元、当日+0.04%，KRMN收45.83美元、当日+1.55%。
- 2026-07-15 01:21 ET市场反应Futu非一手盘前未连续成交时点，BTSG最新价69.67美元，KRMN最新价45.83美元；尚未看到常规盘内充分反应。市场反应:BTSG近5日-0.71%、近20日+10.19%；KRMN近5日-10.96%、近20日-4.18%。
关键理由
- S&P Dow Jones公告BTSG将于2026-07-17开盘前从SmallCap 600调入MidCap 400，指数被动资金换仓形成明确同向买盘。
- 同市场同相位先例显示公告后次日中位反应约+3.2%，但+3日中位转负，适合只抢开盘后短窗口、严控追高。
- BTSG现价69.67美元、市值约136.7亿美元，近20日涨10.2%但近5日未抢跑，事件本身为盘后新公告，仍有隔夜反应窗口。
主要风险
- MidCap/SmallCap指数纳入不是基本面增量，先例中ROKU、SANM等出现高开后回落，若开盘跳空超过3%不追。
- KRMN虽被纳入SmallCap 600，但近13周趋势持续下行且5日跌10.96%，指数流入不足以覆盖趋势风险，暂不做。
反向证据
- 做多前查反向 · 来源 web · 影响 weakens
未找到足以证伪指数纳入的单一新利空，但行情显示KRMN近13周趋势持续走弱、近5日跌10.96%，削弱做多边际。

未发现足以改变BTSG指数纳入交易方向的近期反向证据；主要反证来自先例层面，MidCap纳入后+3日胜率偏低。
