Taiwan's main index closed at an all-time high, and the market is now the fourth biggest in the world by total value — good news for anyone holding Taiwanese tech stocks.

• The index touched a record intraday level before profit-taking trimmed the gain, still closing at a new high.
• Foreign money is pouring in: big investors bought heavily, with foreign buyers making up most of the inflow over the past three days.
• AI demand is the engine — chip, server, circuit board, memory, and testing stocks are leading, and the list of Taiwan's 50 biggest companies is reshuffling faster than in years.
• Taiwan's central bank held rates steady even as the Fed moved, easing pressure on local borrowing costs.
• Gold steadied near recent highs as oil fell and expectations of further Fed rate hikes cooled.

Outlook: The fourth quarter is usually the strongest stretch for stocks, and Taiwan has averaged the best gains of any major market in that window over the past five years.
