美股收涨，AI基础设施与芯片股领涨反弹
US stocks rally as AI shares rebound
Saham-saham AS ditutup lebih tinggi pada hari Rabu, dipimpin oleh saham infrastruktur AI dan semikonduktor. Indeks Nasdaq 100 naik 2,28%, Indeks Komposit Nasdaq naik 1,60%, dan Dow Jones naik 0,48%. CoreWeave melonjak 24,71% karena pendapatan yang lebih kuat, panduan yang lebih tinggi, dan sebagai respons terhadap masalah pendanaan. Tujuh saham terkait AI termasuk Nebius, Sandisk, Arm, dan Micron semuanya mencatatkan kenaikan dua digit. Luasnya pasar menunjukkan 83 keuntungan dan 17 penurunan di Nasdaq 100, namun Microsoft, Meta dan Amazon berakhir lebih rendah di Mag 7.
US AI infrastructure and chip stocks led the rebound, with the Nasdaq 100 up 2.28% and market breadth at 83 advancers versus 17 decliners, indicating broad participation in the rally, but Microsoft, Meta and Amazon closed lower among the Mag 7, suggesting capital favored the AI computing supply chain over large platform stocks. For gold and forex traders, this pickup in risk appetite may weigh on safe-haven demand, but the diverging structure of the rebound means sustainability still requires observation of follow-through conditions.
