📊 2026-05-04 │ 偏多 · 吸貨中
【主線】外資持續流入半導體（+165M），撤出玻璃陶瓷（-23M）。散戶恐慌拋售 GTK（-7.6σ），外資同步買進 — 典型聰明資金分歧訊號，共 15 支觸發。UMC 連續 9 天外資買超（累計 +483M）。
【反證】DELTA 股東人數 4 週暴增 +39.7%，大戶持股下降 -1.1% — 若擴散至更多股票則為派發訊號。AOT 出現 -6.1σ 異常賣出，若為先行指標則主線反轉。
【觸發】觀察 UMC 連買是否中斷（中斷 = 建倉完成）。追蹤 DELTA 下週股東變化 — 加速 = 出場訊號。下一交易日 15:00 更新法人買賣超。
【失效】若外資連續 3 天在半導體轉為淨賣超，吸貨主線失效。
