Foreign institutional investors poured a net NT$69.3 billion into Taiwan equities in the final full week before the Mid-Autumn market closure, helping the TAIEX finish at 48,024.6 points even as on-screen turnover thinned, according to brokerage notes circulated ahead of Monday’s reopening. Dealers now frame the index between 47,000 and 49,000 points as a test of whether overseas funds keep buying once local day traders return from the four-day break.
Holiday hangover for volume
The Taiwan Stock Exchange logged sub-trillion-dollar sessions in the days before the break, a sharp contrast with the NT$1.02 trillion peak seen when TSMC first pushed through NT$2,500. SinoPac Investment Consulting strategist analysts told clients that quarter-end window dressing supported large caps, but many retail accounts stayed sidelined waiting for clearer U.S. tech earnings and Middle East oil headlines.
Monday’s cash session is the first chance to see whether that foreign bid persists without local momentum traders. Historical patterns after long Taiwanese holidays show a one-day volume spike, then a reversion toward the pre-holiday average unless a new thematic story emerges.
Heavyweight chip narrative intact
TSMC shares settled at NT$2,475 on the last session, down 1 percent on profit-taking, while MediaTek closed at a record NT$5,285. AI server supply-chain names including thermal and PCB makers still dominate gainers’ lists in research decks, reflecting continued optimism about 2-nanometer ramp schedules even as the parent foundry negotiates capacity with Apple and Nvidia.
Domestic investment trusts remained net buyers through the holiday week, partially offsetting foreign sales on Thursday. That split matters because trust funds often anchor mid-cap AI hardware names that do not appear in global ETF baskets.
Macro crosswinds
Taiwan traders enter the week watching U.S. Treasury yields and Brent crude after a brief pullback during the break. Higher oil feeds electricity-cost worries for exporters, while firmer yields can pull capital toward dollar assets. Neither shock has broken the TAIEX’s upward channel yet, but both cap how aggressively funds chase multiples above 20 times forward earnings on select AI names.
Practical read for holders
Index investors are less focused on daily point swings than on whether foreign buying repeats for a third consecutive month. A failed follow-through day on Monday would not erase the record highs set in September, yet it would confirm strategists’ view that the rally’s next leg needs volume, not just narrative.
Local banks’ wealth desks are advising clients to stagger entries rather than chase opening gaps, citing the thin liquidity that often appears when Tokyo and Taipei overlap only in the morning session after Japanese holidays.
Calendar ahead
September sales data from major electronics assemblers land later this week, giving a ground-truth check beyond AI press releases. Until then, the NT$69.3 billion foreign inflow figure is the headline number bulls cite—and the thin tape is the caveat bears repeat.
