〔財經頻道/綜合報導〕美股散戶正以罕見的狂熱重返人工智慧市場!Citadel Securities最新數據顯示,上週散戶投資人透過該公司平台淨買進美股91億美元(約新台幣2912億),創近15年來最大單週淨買進紀錄,資金主要湧向半導體與AI基礎設施相關股票,顯示散戶重新押注人工智慧投資主線。
外媒報導,Citadel Securities股票與衍生性商品策略主管Scott Rubner指出,這波買盤並非單純反映市場整體交易熱度升高,而是散戶對特定投資方向展現更強烈的信心。隨著資金重新流入AI相關股票及ETF,納斯達克100指數與標普500指數也雙雙刷新歷史高點,儘管市場對AI泡沫的疑慮仍未消退。

半導體與AI基礎設施成為散戶主要加碼標的。 Rubner的數據顯示,上週散戶淨買進半導體股票約26億美元(約新台幣832億),創過去1年第3高的單週買入規模,也讓10月有望成為該平台半導體股票淨買入規模最大的月份。至於AI基礎設施相關股票,同期也吸引約24億美元(約新台幣768億)淨買入。
值得注意的是,這波資金回流之際,晶片股仍面臨壓力,市場也持續關注AI產業景氣能否延續。散戶卻仍集中買進半導體與AI基礎設施相關標的,反映這些族群依舊是部分投資人押注的主要方向。
Rubner進一步指出,散戶買盤的特徵是方向性押注增強,而非整體交易量擴大。上週散戶買進量比賣出量高出2.7%,方向性偏斜程度達到過去1年周度數據的第90百分位;但整體交易活躍度僅處於過去1年的第42百分位,仍低於平均水準。
換句話說,散戶並非全面增加交易,而是更集中地買進看好的股票,尤其是AI相關族群。這也使近期資金流向成為觀察市場投資情緒的重要指標。
不過,散戶大舉買進並不代表AI股後續漲勢已獲保證。在市場對AI投資熱潮的可持續性仍有疑慮之際,這波創紀錄買盤能否延續,將成為後續觀察美股走勢的重要焦點。
