U.S. stocks staged a strong retaliatory rebound during overnight trading on June 29, leading to a rapid stabilization of overseas market sentiment. This directly eased the selling pressure from foreign capital in the Japanese and South Korean markets. Additionally, nearly 20 leading global semiconductor companies have finalized a new round of concentrated price adjustments and hikes starting July 1. This positive catalyst directly stimulated the Japanese and South Korean markets, both of which have a high concentration of tech and chip stocks.
Furthermore, Samsung Group formally confirmed a massive domestic investment plan of up to 2,655 trillion KRW, focusing on semiconductors, HBM4, advanced packaging, and AI data centers, while SK Hynix also announced an investment of 1,100 trillion KRW to expand its semiconductor supply. This record-breaking investment plan, supported by the South Korean government's comprehensive backing in cross-regional ultra-high-voltage power grids and tax incentives, attracted a massive influx of foreign capital and the "national team" into the tech sector at the market open.
