Japanese Stocks Jump Over 1,000 Points Intraday as Chip Buying Ignites

Japanese stocks jumped over 1,000 points intraday, with buying in AI and chip-linked names—the climax of the same story: a record US Dow lifting global risk appetite, strong AI data-center demand, and a weak yen boosting exporters' FX, pushing the market toward record highs.

Notably the leaders are again the chip supply chain—the very names (Taiyo Yuden, Furukawa) atop the H1 gainers list. The engine is highly concentrated on the AI axis: a strong theme, but deep index dependence on one sector. For Taiwan readers: opportunity, as linked Taiwan-Japan chip chains reflect AI's pull on all of Asia; and risk, since the more concentrated the rally, the sharper the potential fall if AI cools or US stocks retreat. Enjoy the tailwind, but know where the wind comes from.
