U.S. stocks closed higher, with the Dow Jones Industrial Average rising about 1%, reaching a new all-time high. Behind this rebound? The continued surge in AI concepts has become the main driving force. Chip stocks collectively gained momentum and have become one of the recent market focuses. Additionally, the biotechnology and pharmaceutical sector is worth noting, with stocks like Moderna also performing well. Overall, the market's enthusiasm for technological innovation and emerging fields continues to ferment, and the potential signaling effect of this trend on the entire risk asset category is worth investors' consideration.
