Semiconductor Stocks Plunge Amid Political Fears and Weak Guidance
Semiconductor and AI stocks suffered a sharp sell-off driven by weak Intel guidance, U.S. midterm election results, and mechanical selling in leveraged ETFs.
Semiconductor stocks experienced a severe downturn starting October 30, 2026, when the PHLX Semiconductor Sector index dropped 7% in one session. The initial decline was triggered by Intel providing financial guidance that fell below market expectations due to a shrinking personal computer market, leading to price drops for Micron Technology, Broadcom, and Nvidia.
Market volatility intensified on November 5 as shares of Advanced Micro Devices (AMD) fell 13.08%. This second wave of selling followed a Democratic sweep in the U.S. midterm elections, sparking investor fears that a Democrat-controlled Congress might restrict the AI buildout. The sell-off impacted major exchange-traded funds, including the VanEck Semiconductor ETF and the iShares Semiconductor ETF. This occurred despite AMD reporting strong quarterly revenue of $13.377 billion on November 3.
Analysts at Academy Securities attribute the continued pressure to mechanical selling within leveraged ETFs linked to the semiconductor index. They warn that a slowdown in compute spending could damage the broader economy and suggest the volatility will persist until the AI industry improves community outreach and secures state-level commitments for energy and water infrastructure. Despite the short-term turmoil, long-term projections remain high, with Bank of America estimating U.S. semiconductor revenue could reach $3.2 trillion by 2030.
