Regular-session close on Thursday, October 29, 2026, 4:00 p.m. New York time. Stock prices: Yahoo Finance, cross-checked against the closing price on Nasdaq.com. Volume and 30-day average volume: Nasdaq.com. 52-week range: Yahoo Finance daily highs and lows since October 30, 2025. Indices and the 10-year Treasury yield: Yahoo Finance daily closes for the same date.
The stock opened at $431.69, below the previous close of $439.51, and moved between $428.43 and $436.24 during the day. It finished $3.38 above the session low, closer to the bottom of the range than the top. Volume came in at 8.5 million shares, 22.19% below the 10.9 million share average.
The 1.75% decline was 0.37 percentage points deeper than the Nasdaq Composite, which fell 1.38% to 26,184.72. The S&P 500 eased 0.30% to 7,720.39 and the Dow Jones Industrial Average slipped 0.25% to 52,342.56, while the US 10-year Treasury yield fell 5.6 basis points to 4.99%.
Chip names were mostly lower. Nvidia (NVDA) fell 0.80%, AMD (AMD) dropped 2.08%, Broadcom lost 1.94% and Micron declined 4.98%, while lithography supplier ASML (ASML) gained 0.77%. At the close, TSMC sat 11.42% below its 52-week high of $487.47 and 61.84% above its 52-week low of $266.82.
No source we fetched named a TSMC-specific cause for the October 29 decline, so the move is best read against the wider market. Financial media tied the day's tech weakness to Alphabet's third-quarter revenue miss, which revived concerns about heavy AI capital spending, according to Reuters. Alphabet (GOOGL) closed down 12.64% on the day.
Semiconductor stocks snapped a four-day winning streak on October 29, Reuters reported, as investors tried to separate companies that can fund their large AI plans from those burning cash and borrowing to pay for them. TSMC's decline was in line with that sector move rather than tied to an announcement of its own.
TSM Stock Analysis: Supporting Factors and Risks
Supporting Factors
TSMC reported third-quarter revenue of $46.72 billion, up 41.2% year over year in US dollar terms, with a gross margin of 66.4%, according to the company's third-quarter earnings release dated October 15, 2026.
The company guided fourth-quarter revenue of $52.3 billion to $54.3 billion. CFO Wendell Huang said TSMC expects "continued strong demand for our leading-edge process technologies, including the steep ramp-up of our 2-nanometer technology."
Bell Global Equities Fund's third-quarter letter, as reported by Insider Monkey on October 29, cited TSMC's August sales rising 36% year over year and a collaboration with ASML on High-NA EUV lithography, where "commercial adoption is not expected until 2030 onwards."
Risks
Doubts over AI spending weighed on the whole chip group on October 29, and Reuters reported investors were sorting AI spenders that can fund their plans from those burning cash and borrowing.
Four construction workers died at TSMC's new factory site in Kaohsiung on October 20, and the company suspended similar steel structure work at all its construction sites across Taiwan pending its investigation, according to Reuters as published by The Star.
TSMC's own release lists cyclicality and market conditions in the semiconductor industry among the risks that could make actual results differ from its outlook.
