美國銀行（BofA）分析師團隊研究指出，過去2年形成的大型科技股泡沫仍在擴大，美國大型科技股還有上漲空間，投資人或可布局獲利。
根據《彭博》報導指出，美銀分析過去一個世紀的十次股市泡沫，發現股票被極端高估的泡沫期間，平均漲幅為244%。再觀察這波美股科技七巨頭的波動，由2023年3月低點到現在，漲幅為223%，仍有上漲空間。
美股七巨頭其中包含蘋果（Apple）、輝達（Nvidia）、微軟（Microsoft）、Alphabet 、亞馬遜（Amazon）、Meta 和特斯拉（Tesla）等大型科技股 。
就科技七巨頭目前的估值來說，支持了股價再往上攻的可能。美銀分析師表示，歷史上的股市泡沫通常以58倍的本益比、股價較200日移動均線高出29%，迎來泡沫破裂。現在的美股科技七雄本益比為39倍，股價較200日均線高出20%。
上周美銀公布基金經理人調查，42%受訪者認為近兩個月最擁擠的交易是在「做多」科技七巨頭。分析師也提醒，投資人若要對沖風險，應配置部分「不良價值股」，以應對大型科技股泡沫。
