Japanese and South Korean stock markets suddenly launch a broad comeback! SoftBank surges, is the AI rally back?

After the pullback in recent days, Japanese and South Korean stocks quickly staged a “deep V-shaped rebound.” On September 4, the Nikkei 225 rose 1.26%, the KOSPI rose 1.64%, and SoftBank became the market’s main focus.
The core keywords behind this rally remain technology and AI. After Federal Reserve officials sent relatively dovish signals, U.S. Treasury yields fell and sentiment toward U.S. tech stocks recovered, naturally giving Asian semiconductor and AI supply chains a “recharge.”
SoftBank’s sensitivity was particularly evident, as the company itself is viewed by the market as an important barometer for AI investment. After plunging more than 6% the previous day, it quickly rebounded, showing that investors’ enthusiasm for AI assets has not disappeared—they are simply searching for a new short-term price balance.
However, a rebound does not mean the risks have disappeared. Bank of Japan policy, the yen’s trend, and developments in the Middle East will continue to affect risk appetite.
So is this wave more like a “sentiment recovery,” or the starting point of a new rally?
I’m more focused on whether SoftBank can turn this rebound into a trend, rather than merely being a one-day firework.#日韩股市走强软银涨近6%
