30-second brief

Taiwan stocks opened higher but moved lower on the 29th, plunging 667 points to close at 46368, with combined listed and OTC turnover exceeding 1 trillion yuan, TSMC, UMC and other heavyweights leading declines, OTC falling 1.83%, with brokerages noting AI valuation concerns persist and advising risk control until stabilization before rebuilding positions

Weighted Index Plunges 667 Points, Turnover Exceeds 1 Trillion Yuan

Taiwan stocks opened higher but moved lower on the 29th, with the weighted index closing at 46368.33 points, down 667.25 points, or 1.42%. The broader market trended lower in early trading, falling below the 46000-point mark intraday, before bargain buying emerged and losses narrowed slightly. Turnover in the listed market reached 7891.52亿元, plus 2127.33亿元 in the OTC market, totaling 1兆18.85亿元. A total of 912 listed stocks fell and 320 rose, while 728 OTC stocks fell and 352 rose, showing more decliners than advancers, as market willingness to chase higher turned cautious.

OTC Weakens in Sync, Small- and Mid-Caps Under Pressure

The OTC index, representing small- and mid-cap stocks, weakened in sync, closing at 387.37 points, down 7.24 points, or 1.83%, indicating selling pressure was not confined to large-cap heavyweights. Although major U.S. stock indexes closed higher across the board on the 28th for a third straight gain, Taiwan stocks failed to follow the international rally. The U.S. Federal Reserve kept interest rates unchanged as expected, with Chair 華許 reiterating determination to fight inflation, but without clearly signaling whether rates will rise again in December, as the market continues to watch future rate direction, while Oracle surged nearly 11% on its long-term revenue outlook and semiconductor stocks strengthened in tandem.

Electronics Heavyweights Lead Declines, Mixed Performance Among Stocks

Heavyweight stocks were the main drag, with TSMC closing at 2415 yuan, down 10 yuan, or 0.41%. UMC closed limit-down at 115.5 yuan, down 12.5 yuan, or 9.77%. MediaTek closed at 4045 yuan, down 190 yuan, or 4.49%. Delta Electronics closed at 1480 yuan, down 70 yuan, or 4.52%. Elite Material closed at 745 yuan, down 33 yuan, or 4.24%. Kinsus closed at 959 yuan, down 76 yuan, or 7.34%, reflecting rising short-term profit-taking pressure on electronics stocks. There were still bright spots, with Win Semiconductors surging 54 yuan to close at 594 yuan, hitting the daily limit with a 10% gain, Walsin Technology rising 25 yuan to close at 423 yuan, up 6.28%, and Nanya Technology closing at 477 yuan, flat.

Brokerages Cite AI Valuation Noise, Watch 46000 Level

Lun Yuan Investment Advisor 陳學進 believes that mixed earnings from tech giants, with Microsoft up over 4% after hours, SK Hynix ADR and Oracle soaring over 10%, while Alphabet fell over 7% after hours on weaker-than-expected advertising revenue, combined with the upcoming U.S. midterm elections, unresolved Middle East tensions, elevated energy prices, slower-than-expected AI monetization progress and excessive capital expenditures, have again raised concerns about overvalued AI and bubble risks. Qifa Investment Advisor 容逸燊 believes Asian stocks pulled back on Google earnings, with both yesterday's rebound and today's decline on shrinking volume, and the outlook not yet bearish unless 45000 is breached, but individual stock volatility has increased, so investors should watch whether TSMC can stop falling and whether 46000 can hold, while controlling position risks.
