The recent US Midterm Elections have sent shockwaves through global financial markets, particularly impacting the AI and [semiconductor](/topic/semiconductors) sectors. Following the Democratic Party's decisive victory, a massive sell-off ensued, resulting in a staggering $2.5 trillion loss in wealth across Wall Street and other major stock exchanges worldwide. This article delves into the ramifications of the election results on various indices and sectors, highlighting the significant losses incurred by key players in the technology market.
US Stock Market Reaction to Midterm Election Results
The immediate aftermath of the US Midterm Elections on November 5, 2026, saw the tech-heavy Nasdaq Composite index plummet by over 5.50%, closing at 24,315 points. This marked one of the worst days for the index since 2025, as investors reacted to the implications of a Democratic-controlled Congress. The Dow Jones Industrial Average also felt the brunt of the sell-off, dropping nearly 3.50% to finish at 51,523, while the S&P 500 index fell by 4.36%. The overall market sentiment was grim, with major indices collectively erasing approximately $2.5 trillion in market capitalization.
Among the hardest hit were flagship AI and semiconductor stocks. [NVIDIA](/topic/nvidia), often regarded as the poster child of the AI revolution, saw its share price drop from $200.13 to $181.60, reflecting an intraday loss of 9.26%. Similarly, Advanced Micro Devices (AMD) shares fell from $452.50 to $404.40, a staggering 17.26% decline. Micron Technology Inc. was not spared either, with shares closing down 17.46% at $656.39.
Global Market Impact: Asia Takes a Hit
The repercussions of the US election results were not confined to American shores. Asian markets, particularly those heavily invested in technology, experienced significant declines. The Japanese Nikkei 225 index fell from 62,188 to 57,269, marking a 7.90% loss. South Korea's KOSPI index suffered even more, crashing from 5,683 to 5,069, a dramatic 10.80% drop over two trading sessions.
Taiwan's TAIEX index also reflected the turmoil, nosediving from 42,948 to 39,701, a loss of 7.56%. The sell-off in these markets was largely attributed to the heavy exposure to AI and semiconductor stocks, which were already under pressure from the US market's decline.
Semiconductor Stocks in Focus: A Closer Look
In Japan, the sell-off was particularly pronounced among semiconductor stocks listed on the Nikkei 225. SoftBank Group shares plummeted from 4,269 Japanese Yen to 3,564 Yen, a decline of 16.51%. Advantest Corp shares fell nearly 18.50%, finishing at 28,200 Yen, while Tokyo Electron shares dropped from 9,663 Yen to 8,290 Yen, a loss of 14.20%.
The situation was dire in South Korea, where the KOSPI's heavy reliance on semiconductor manufacturing led to emergency circuit breakers being activated to halt trading. SK Hynix's shares crashed 13.40% on Friday alone, contributing to an overall decline of nearly 18% over two sessions. Samsung Electronics also faced a significant downturn, with shares falling around 13.50% following the election results.
Mixed Reactions in Chinese Markets
Interestingly, while the global tech sector faced a rout, Chinese markets displayed a mixed reaction. The CSI 300 Index in mainland China fell by 1.45% on Friday, but it had seen gains on Thursday after the election results. Investors appeared to rotate out of global semiconductor positions, favoring deeply discounted Chinese internet platforms that are less tied to the US supply chain.
In Hong Kong, the Hang Seng Index experienced a slight decline of 0.92% on Friday, although it had seen strong buying activity the previous day. This divergence highlights the complexities of the global market landscape, where local factors can sometimes buffer against broader trends.
