Taiwan's stock market jumped sharply, a clear positive for tech and chip investors as memory stocks and TSMC led the charge back above a key technical level.

• Taiwan's benchmark index surged over 750 points (about 1.6%) in early trading, with TSMC, MediaTek, Foxconn, and Delta Electronics all climbing; memory chip makers like Nanya Technology and Winbond also rallied hard.
• US markets closed higher too, driven by AI and chip stocks after Anthropic filed for its IPO, lifting Broadcom and pulling AMD, Micron, and Nvidia along with it; oil prices fell on hopes of an Iran ceasefire.
• Markets widely expect the Fed to hold rates steady this week, with a possible rate cut in December, while Chinese AI models are rapidly gaining global market share thanks to lower cost, squeezing US firms on pricing.
• Nanya Technology and Winbond remain in favor as memory demand returns, while bulls argue Taiwan's market has found a short-term bottom even though Wall Street figures like Jamie Dimon and Jeremy Grantham are warning of an AI bubble and a possible sharp stock drop.
• Corporate news: a major stake in Taipei 101 is changing hands to a Ting Hsin Group-linked investment firm, chipmaker Macronix posted record quarterly profit, and passive-component maker Yageo rallied on a bullish foreign brokerage price target.

Outlook: Taiwan's market looks set to stay volatile, with the key support zone intact for now but a reclaim of the longer-term trend line still unconfirmed.
