台積電 Leads Strong Market Rebound
Taiwan stocks opened strongly on the 28th, with the weighted index opening at 46812.51 points, surging 716.28 points, or 1.55%, showing active buying returning. Heavyweight leader 台積電 (2330) rose 25 to 2425, up about 1.04%, retaking the 2400 level and providing key support for the market rebound. The OTC index representing small and mid-cap stocks rose 10.21 points to 389.41 points, up 2.69%, with large-cap and small/mid-cap stocks rebounding together.
Glass, Plastics and Electronics Groups Rise Together
Among listed sectors, glass led with a 4.62% sector index gain, with 中台玻 up 8.90%. Plastics rose 3.75%, with 南亞 up 4.54%. Electronic components rose 3.73%, with 欣興 surging 5.19%. Optoelectronics rose 3.36%, with 玉晶光 jumping 6.20%. All gains beat the broader market, showing funds spreading from heavyweights to electronic components and optics groups. Among concept stocks, the Google TPU concept index rose 4.0%, third-generation semiconductors rose 3.72%, 5G concept stocks rose 3.71%, and Thunderbolt 5 concept stocks rose 3.36%, with 中華星光 up 4.60%.
Returning US AI Buying Lifts Sentiment
The rebound was mainly driven by stronger U.S. stocks on the 27th, with AI-themed buying returning, plus falling international oil prices easing cost concerns. The S&P 500 rose for a second straight day, while the Dow Jones Industrial Average edged up about 16 points despite a drag from Boeing's sharp drop. 倫元投顧陳學進 noted that Anthropic's IPO filing and Meta's $25 billion bond offering seeing 5x oversubscription, with Broadcom and AMD leading gains and the Philadelphia Semiconductor Index surging over 3.6% to stand above the 10-day moving average, margin balances falling sharply by 20.9 billion in two days combined, and easing foreign-investor selling pressure, all favor a Taiwan stock rebound. He believes AI remains the main investment theme, shifting toward specification upgrades, with upgrade demand in CPO optical communications, power, cooling, PCB and memory.
Sustainability of Rebound Still to Be Seen
On the weak side, sports and leisure stocks fell 0.86%, with 寶成 down 0.58%. Food stocks fell 0.68%, with 統一 down 1.12%. Auto stocks fell 0.47%, with 中華汽車 down 4.00%. Digital cloud stocks fell 0.47%, while GOGOLook rose 1.51%. 啟發投顧容逸燊 said the index is temporarily supported between 45,000 and 46,000 points, the Taiwan dollar has not made a new low, and Japanese and Korean passive-component leaders have not broken new lows, with a chance for a recovery in November to be watched. Going forward, it remains to be seen whether 台積電 can hold steady at 2400 and whether OTC strength continues, with chasing highs not advised, attention to intraday profit-taking sell pressure, and focus on the removal of uncertainty after the U.S. midterm elections and Anthropic listing fund flows.
