Dow Rallies on Political Shifts While Chip Stocks Plunge Amid Earnings Disappointments
The Dow posted its strongest gain in 19 months after a Democratic congressional sweep, boosting investor confidence. However, semiconductor stocks declined sharply as Qualcomm and Arm missed earnings expectations, triggering a broad selloff across Asian tech markets. Chinese tech shares rose on hopes of tariff relief, with Tencent advancing on the launch of its new AI model.
On November 4, 2026, the Dow Jones Industrial Average surged 3.19%—its best performance in 19 months—following a decisive Democratic sweep of both chambers of Congress, which lifted investor confidence and triggered broad risk-on sentiment across consumer services, healthcare, and financials. However, this macro optimism was sharply offset by a steep selloff in semiconductor stocks, driven by disappointing earnings from Qualcomm and Arm. Qualcomm missed handset revenue forecasts, while Arm’s forward guidance fell short, sparking a wave of sell-offs that extended to Asian markets, with South Korea’s KOSPI hitting a trading halt and SK Hynix dropping 7.2% and Samsung Electronics sliding nearly 6%. Meanwhile, Chinese tech stocks rose on hopes of tariff relief, led by Tencent, which gained 6% after launching its Hunyuan AI model. In contrast, Microsoft declined to expand its AI partnership with UK-based Nscale or proceed with a Texas data center lease, signaling caution in the AI infrastructure space despite rising demand. Other notable moves included SoftBank’s 5.1% drop after China blocked its $5.4 billion acquisition of ABB’s robotics unit, and NextDC surging 43% on strategic investments from Goodman Group and Digital Realty. The energy sector also faced headwinds, with CNOOC and PetroChina falling 2.9% and 3.4% respectively due to a sharp drop in crude oil prices, which simultaneously boosted airline stocks like Alaska Air (+9.1%) and JetBlue (+10.1%).

The market’s bifurcated reaction—strong macro momentum from political clarity versus deep sector-specific distress—highlights the fragility of investor confidence in an era of rapid technological transition. While the Democratic sweep may ease trade tensions with Japan and China, boosting exporters and tech firms reliant on global supply chains, it also raises uncertainty around defense spending and AI infrastructure investments, particularly in politically sensitive regions like Texas. The semiconductor selloff underscores how earnings quality can override political optimism, especially in capital-intensive industries where margins are under pressure. This dynamic echoes the 2018–2019 tech correction, when strong macro trends were undermined by inventory glut and margin erosion in semiconductors. Looking ahead, the market may continue to oscillate between policy-driven rallies and microeconomic disappointments, particularly as AI firms like OpenAI prepare for a potential 2027 IPO amid
