US stock markets closed lower on July 17, 2026, as semiconductor shares took a hit following Taiwan Semiconductor Manufacturing Company’s (TSMC) announcement of increased capital expenditure. The Dow Jones Industrial Average slipped 0.20% to 52,552.97, the S&P 500 dropped 0.51% to 7,533.77, and the Nasdaq Composite also declined, reflecting investor caution amid mixed earnings signals.
Alphabet, the parent company of Google, saw its shares fall more than 4%, contributing to the broader tech sector weakness. Other major tech firms including Nvidia and Amazon also experienced declines, with Nvidia down 2.4% and Amazon falling nearly 2%.
Why TSMC’s Earnings Impacted the Market
TSMC, the world’s largest semiconductor manufacturer, reported second-quarter revenue of $40.20 billion, marking a 33.7% increase year-over-year and a 12% rise from the previous quarter. Despite this strong revenue growth, the company raised its capital expenditure forecast for 2026 to between $60 billion and $64 billion, up from the prior estimate of $52 billion to $56 billion.
Wendell Huang, TSMC’s Senior Vice President and Chief Financial Officer, highlighted robust demand for the company’s advanced chip-making technologies, including a significant ramp-up in 2-nanometer process technology expected in the third quarter. However, the increased spending outlook raised concerns among investors about potential pressure on profit margins and future returns.

How This Affects Investors and the Tech Sector
The semiconductor industry is a crucial driver of the technology sector and broader economy, supplying chips used in everything from smartphones to cars. TSMC’s decision to increase capital spending signals confidence in long-term demand but also introduces short-term uncertainty about costs and profitability.
Investors reacted negatively to the higher expenditure forecast, fearing it could weigh on earnings despite strong sales growth. The sell-off in chip stocks dragged down major indexes, highlighting how sensitive markets are to shifts in capital investment plans within this sector.
Alphabet’s sharp decline added to the tech sector’s challenges, as investors weighed concerns about growth prospects and competitive pressures. The drop in SpaceX shares below its IPO price also indicates volatility among newly listed tech companies.
