AI Semiconductor Stocks Have Fallen Sharp, Yet AI Infrastructure Spending Continues Growing. Is This a Buying Opportunity? Semiconductor stocks suffered a sharp selloff on November 5, with the Philadelphia Semiconductor Index (SOX) plunging 12%. The immediate catalyst was Democratic victories in the US midterm elections, raising concerns about tighter regulation and slower data-center construction. Voters favored restrictions on data-center development in 40 of 41 local ballot measures, reflecting growing concerns about electricity prices, power-grid capacity, and water consumption. The correction has been substantial. From their 52-week highs: $SNDK -65%, $ARM -61%, $INTC -60%, $MRVL -57%, $AMAT -55%, $KLAC -55%, and $LRCX -54%. AI leaders also suffered: $MU -45%, $AVGO -41%, $AMD -32%, $ASML -29%, $NVDA -23%, and $TSM -23%. However, political uncertainty is only part of the problem. Hyperscaler CAPEX is growing significantly faster than operating cash flow, raising concerns about financing requirements and long-term returns on AI investments. High valuations have further increased market sensitivity to execution risks. Yet AI demand is strong. J.P. Morgan forecasts $900B in global AI CAPEX in 2026, with cumulative investment reaching $5.5T by 2030. Jefferies called the move "reactionary, not a fundamental reset". Demand for GPUs, HBM, custom accelerators, and advanced semiconductor manufacturing continues supporting industry growth. Is the Market Overreacting to Political and Financing Risks?
