iShares PHLX SOX Semiconductor (SOXX) stock analysis, February 6, 2026: SOXX breaks $346 after ASML beat and Nvidia H200 approval — can it retest $359?

Published February 6, 2026 · SOXX chart, levels and live analysis

Key Updates

SOXX has surged 5.21% to $347.60 since the February 5 report, decisively breaking through the $346 resistance level and reversing four consecutive sessions of losses. This sharp recovery was catalyzed by a sector-wide rally following ASML's strong Q4 earnings beat and reports of China approving Nvidia's H200 chip sales to major domestic tech companies. The ETF now trades 15.42% above its 2026 starting level, though still 3.1% below the January peak of $358.83. The rapid reversal from the $330.38 low represents a 5.2% bounce in a single session, suggesting robust institutional buying and renewed confidence in semiconductor fundamentals driven by AI infrastructure demand.

Current Trend

SOXX has recovered strongly from the recent correction, posting a 5.07% single-day gain and maintaining positive momentum across all timeframes: +0.38% over 5 days, +6.99% over 1 month, and +46.71% over 6 months. The YTD performance of +15.42% significantly outpaces broader market indices, reflecting sustained investor appetite for semiconductor exposure. The ETF has reclaimed the critical $346-347 support zone that held during late January consolidation, establishing a technical foundation for potential retesting of the $358.83 January highs. The 6-month performance of 46.71% demonstrates the sector's exceptional momentum, driven by AI infrastructure buildout and memory chip supply constraints.

Investment Thesis

The semiconductor sector remains positioned at the intersection of multiple structural growth drivers: AI datacenter expansion requiring trillions in infrastructure investment, memory chip supply constraints with 2026 HBM fully allocated, and government-backed reshoring initiatives including $250 billion in Taiwanese investments and CHIPS Act funding. Equipment shortages limit production expansion capacity, creating pricing power for manufacturers. Major foundries including TSMC are increasing capital expenditure to $56 billion annually, signaling confidence in sustained demand. The sector benefits from both supply-side constraints (equipment bottlenecks, limited HBM capacity) and demand-side acceleration (AI model training, edge computing proliferation). However, tariff uncertainties and geopolitical tensions introduce policy risk that could disrupt supply chains or increase production costs.

Thesis Status

The investment thesis has strengthened materially with the latest developments. ASML's Q4 orders exceeding expectations and 2026 sales guidance ahead of estimates validate equipment demand projections, while China's approval of Nvidia H200 sales removes a significant $8 billion revenue risk and expands addressable markets. SK Hynix's record 2025 profit confirms memory pricing strength, supporting the supply constraint narrative. The sector's ability to rally 5% in a single session on positive earnings and policy news demonstrates strong underlying demand and institutional conviction. Near-term risks from the recent 5.5% correction have dissipated, though the ETF remains 3.1% below January peaks, suggesting room for further upside if momentum continues. The convergence of strong earnings, favorable policy developments, and equipment constraints reinforces the structural growth thesis.

Key Drivers

The immediate catalyst was ASML's Q4 earnings beat with orders exceeding expectations and 2026 sales forecast ahead of estimates, driving its shares up 5% in European trading. The rally intensified following reports that China approved ByteDance, Alibaba, and Tencent to purchase Nvidia H200 chip systems, a critical development addressing prior concerns over $8 billion in potential lost sales from export restrictions. SK Hynix shares closed more than 5% higher after reporting record full-year 2025 profit, validating memory market strength. These company-specific catalysts reinforced broader sector momentum from TSMC's 35% profit increase and plans to increase capital spending in 2026, signaling sustained confidence in AI-driven demand across the ecosystem.

Technical Analysis

SOXX has executed a sharp reversal from the $330.38 low, reclaiming the $346-347 support zone that previously acted as consolidation support during late January. The 5.07% single-day gain on substantial volume indicates institutional accumulation and marks the strongest daily performance since the January rally. The ETF now trades in the middle of its recent range between $330 support and $359 resistance, with immediate resistance at the $350-352 level. The 1-month gain of 6.99% and 6-month surge of 46.71% maintain the dominant uptrend, while the 5-day performance of +0.38% reflects the recent volatility and consolidation. Key technical levels include support at $346 (previous resistance turned support), $340 (10-day moving average area), and $330 (recent low), with resistance at $352, $359 (January peak), and $365 (psychological level). The rapid recovery from oversold conditions suggests strong buying interest on pullbacks.
