Geopolitical whipsaw remains the dominant driver, now easing. Brent spiked above $100 (touching $100-120 fear territory) as Iran conflict hit 13 nights, Houthis opened a Red Sea front against Saudi tankers, and Strait of Hormuz traffic collapsed to ~15% of normal. But by Monday (7/27), US-Iran struck a reported hiatus in hostilities (Iran denies formal "10-day ceasefire" but strikes paused), sending Brent/WTI down 5%+ and igniting a broad risk-on rally (Nasdaq futures +1.6%, VIX -5%, Kospi/chip stocks surging). Treat oil headlines as the single biggest swing factor — fade extreme moves in either direction given the pattern of escalation-then-de-escalation. Fed hike odds are volatile (was 80%+, now back to ~62% hold/37% hike) into Wednesday's meeting; Warsh is deliberately opaque, board is split.
Memory/semiconductor sector had its most violent chapter yet. Korean chip stocks (Samsung, SK Hynix) crashed 7-11% Thursday-Friday on Middle East risk-off plus China's CXMT IPO (surged 466-535% on Shanghai debut, ~$488-540B valuation, China's largest tech IPO) drawing rotation. This followed SK Hynix/Samsung/Nvidia/Broadcom announcing ~$950B in AI chip supply deals (HBM, foundry through 2030) — bullish fundamentally but stocks sold the news. By Monday, memory names ripped back on the ceasefire-adjacent rally. New and important: Nvidia's $750B+ deal wave (SK Group $500B+ Korea data centers, OpenAI $250B guarantee + $350B financing for a 10GW Ohio hub) is reviving serious "circular financing" criticism from Chanos, Burry, Zitron — watch this as a growing bear thesis alongside Burry's oil/AI-debt warning. Wall Street (Bernstein, Morgan Stanley, Evercore) broadly still frames memory selloffs as buying opportunities, citing structural DRAM/HBM shortage into 2027-2028, though CXMT is a genuine new competitive threat long-term (Micron/SK Hynix seen as insulated near-term).
Big Tech earnings delivered "good numbers, bad reaction" again. Alphabet and Tesla both fell hard despite beating revenue (Tesla -14-19% week, worst in a year); Alphabet's capex raise ($195-205B) hit Meta/Microsoft/Amazon while boosting memory/industrials — Josh Brown's "market broadening" thesis (insurers, industrials, energy) continues to play out. Nvidia remains a laggard versus every AI-adjacent rally. This week's megacap earnings (Microsoft, Meta, Apple, Amazon) plus Fed decision Wednesday are the key tape-setters — expect elevated volatility given stretched AI capex scrutiny, oil/Fed crosscurrents, and Korea's leverage-driven amplification of every swing.
