Semiconductor Cycle: AI Capex, Memory and the SOX Trade
Live coverage of the AI semiconductor cycle — NVDA, AVGO, AMD, ASML, memory demand, capex run rates and overbought signals.
The semiconductor cycle is the largest single-sector trade of the post-COVID era. AI capex from hyperscalers (MSFT, GOOGL, META, AMZN) and sovereign cloud build-outs has pushed NVDA market cap above $5 trillion, AVGO and ASML to record highs, and the SOX index to repeated overbought readings. Every major macro print and earnings cycle revolves around whether the AI capex run rate ($250B+ annually) is sustainable or peaking.
This hub aggregates the narratives behind the cycle: capex announcements, supply-demand for memory (HBM, GDDR), trade-restriction policy on advanced chips, and the technical overbought signals (RSI, SOX vs SPX ratio) that have called every meaningful pullback. Cross-references to ROIC, panic selling, and option Greeks help frame both the long-thesis and the downside risk.

Frequently asked
How big is the AI capex run rate in 2026?
Combined capex from MSFT, GOOGL, META, AMZN, AAPL and sovereign cloud customers is running at roughly $250 billion annualized. Estimates for 2027 range from $300B (bear case) to $450B (bull case). Most of that flows to NVDA, AVGO, ASML and the memory manufacturers.
Why does ROIC matter for semiconductor stocks?
Capital-intensive businesses live and die by their ROIC. NVDA at 60%+ ROIC reinvests profits at extraordinary rates of return; lagging foundries at 8% ROIC compound much more slowly. The market multiple gap between high-ROIC and low-ROIC semis is among the widest in any sector.
What does it mean when semiconductors are overbought?
SOX RSI above 70 across multiple timeframes plus the SOX/SPX ratio at multi-year highs plus single-stock concentration above 35% in mega-caps are classic overbought signals. Every major semi correction since 2018 has been preceded by all three triggering.
Which ETFs give exposure to the semiconductor cycle?
SOXX (iShares) and SMH (VanEck) are the two main semi-ETFs. SMH skews more to NVDA and TSM; SOXX is more diversified across equipment makers. SOXL is a 3x levered version for short-term tactical exposure.
