TSMC Leads TAIEX Rebound After Fed Clarity
TSMC’s 2% gain anchors a 1,000-point TAIEX surge as petrochemical and optical sectors rally, driven by the elimination of Federal Reserve uncertainty and a subsequent futures short squeeze.
The TAIEX index surged 1,025.94 points intraday to a high of 46,874.84, reclaiming the monthly moving average at 46,166 points. This sharp rebound followed the conclusion of the U.S. Federal Reserve's interest rate decision, which removed a key source of monetary policy uncertainty. At 10:54 a.m., the index stood at 46,492 points, up 1.4%, with turnover reaching NT$502.959 billion. Market participants reported that the recovery of short-term moving averages was accompanied by a significant expansion in trading activity across the board.
TSMC (2330.TW) served as the primary driver of this rally, rising NT$50 to NT$2,430 intraday, a gain exceeding 2%. The contract chipmaker’s performance boosted broader market sentiment, prompting investors to chase higher prices. Other heavyweight electronics firms followed suit, with MediaTek (2454.TW) climbing NT$90 to NT$4,620 and Hon Hai (2317.TW) adding NT$4 to NT$252. Delta Electronics (2308.TW) and United Microelectronics (2303.TW) also posted gains, reflecting a broad-based recovery in the sector that tracks the majority of the index’s weight.
Petrochemical and Optical Sectors Lead
Petrochemical stocks emerged as a focal point for buyers, with Formosa Petrochemical and Nan Ya Plastics both surging more than 6% intraday. Formosa Chemicals & Fibre and Formosa Plastics each gained over 3%, contributing to a sharp sector-wide advance. Simultaneously, the optical communications group maintained bullish momentum, driven by Visual Photonics Epitaxy hitting the daily limit and Create Technology rising more than 4%. IET-KY (4971.TW) and LandMark Optoelectronics (3081.TW) also posted double-digit percentage gains, indicating strong demand in these specialized hardware segments.
The AI thermal management sector extended its strength, benefiting from rising power consumption in AI servers. Asia Vital Components (3017.TW) rose over 4%, while Auras Technology (3324.TW) gained nearly 4%, driven by expanding demand for cold plates and coolant distribution units. In individual news, Winbond Electronics (2344.TW) announced the acquisition of Infineon’s NOR Flash and F-RAM businesses. The stock jumped more than 6% in early trading as investors assessed the move’s impact on Winbond’s product portfolio and customer base in the niche memory market.
Futures Short Squeeze Fuels Capital Flows
Market dynamics shifted significantly as prior hedging positions were unwound. Investors who had established short futures positions to hedge against Federal Reserve policy uncertainty progressively covered these bets once policy clarity emerged. This action created a short-squeeze rally that propelled prices higher. According to GN stocks/shares-surge, the dissipation of monetary policy uncertainty triggered a rapid return of capital flows, reinforcing the upward momentum in heavyweight names and expanding overall market turnover.
The TPEx, which tracks small- and mid-cap stocks, rose a modest 0.08% during the session. The electronics sub-index gained 1.2%, while the financial sub-index advanced 0.8%. Analysts projected that full-day turnover could expand to the NT$800 billion level, reflecting the broad participation in the rally. The combination of corporate-specific upgrades, such as Winbond’s acquisition, and macro-level relief from rate uncertainty provided a dual-engine effect for the market’s performance on the 17th.
