Earnings Lift The Dow. Memory Melts Down.

Rundown · 2026-07-29

A tale of two tapes: blue-chip earnings beats (KO +5%, SHW +7%, BA +5%) drove the Dow +537 to a 3rd straight win, but a memory-chip rout cratered KOSPI -11% and MU -9%, holding the Nasdaq -0.22%. Oil fell below $80; 10Y eased to 4.60%. Fed decides today.

Market Performance

• S&P 500: 7,428.78 (+0.21%) — broad gains edged out the semiconductor drag
• Nasdaq: 24,876.91 (-0.22%) — chips sank it; recovered from as much as -9.3% intraday
• Dow: 52,747.32 (+1.03%) — +537.24 pts, 3rd straight win; 6 blue-chips = ~460 pts of it
• Russell 2000: +0.19% — small caps joined the broad, non-tech advance
• Sector leaders: Staples (KO), Industrials, Materials (SHW) · Laggards: Semis (SOX -4.5%)
• 10Y yield: ~4.60% — eased for a 3rd day; DXY softer as oil fell
• WTI crude: $79.26 (-4%) — Iran discussed the Strait of Hormuz with Saudi Arabia + Oman
• Megacaps calm: GOOGL +1.85%, MSFT +1.09%, AAPL +0.94% (touched $5T intraday)

Memory Melts Down: China's ChangXin Shock

• KOSPI -10.84% — triggered trading halts; SK Hynix + Samsung crashed; Nikkei -3.95%
• China's ChangXin (CXMT) completed an $8.6B Shanghai IPO — threatens to flood commodity DRAM
• The fear: CXMT scales cheap DRAM + compresses Korean-maker margins regardless of AI demand
• A different threat than an AI-capex slowdown — structural pricing pressure that won't fade
• MU -8.9%, AMD -8.1%, AMAT -7.8%, TSM -3.5%; SOX -4.5%, its 4th straight losing session
• ASML -5.2% — a report that China is building DUV lithography machines widened the scare

Blue-Chip Earnings + Oil Relief Power the Rotation

• KO +5% — top + bottom beat + raised outlook; its best day since 2009
• SHW +7%, BA +5%, PII +4.7%, PYPL up — the non-tech earnings wave lifted the Dow
• Q2 earnings hot: ~a third reported, 85% beating; growth revised to ~37% (from 22%)
• Oil below $80 on Hormuz diplomacy — a 2nd day of energy relief cooling inflation
• META + MSFT report today, AMZN + AAPL Thursday — the megacap-capex reads keep coming

Notable Movers

• (IQV) +14% — Beat Q2 (revenue $4.37B, +8.7% YoY, vs $4.3B est), record bookings + raised guidance
• (BA) +5% — Posted a faster-than-expected return to positive free cash flow
• (MU) -9% — Chinese memory maker ChangXin completed its IPO, reigniting pricing-undercut fears

Private Dealmaking

• Spur Intelligence (IP intelligence) — $200M
• Dwelly (residential letting) — $178M
• Claris Bio (corneal disease tx) — $118M
• Enigma (robot-engagement AI) — $71M
• Paper (agentic-AI design) — $34M
• Nuclidium (radiopharma · Germany) — $33M

TLDR

• S&P +0.21% to 7,428.78; Dow +537 pts (3rd straight win); Nasdaq -0.22% on chips
• KOSPI -10.84% (trading halts) as China's ChangXin $8.6B IPO threatens to flood DRAM
• MU -8.9%, AMD -8.1%, AMAT -7.8%; SOX -4.5% (4th straight loss); ASML -5.2% on China DUV report
• KO +5% (best day since '09), SHW +7%, BA +5% — blue-chip beats powered the Dow
• WTI -4% to $79.26 on Hormuz diplomacy; 10Y eased to 4.60%; megacaps green
• 85% of reporters beating; growth ~37%; META+MSFT today, AMZN+AAPL Thu; Fed decides

The Bottom Line

The rotation thesis got its cleanest print yet — the Dow rose 537 points the same day the KOSPI crashed 11%. Blue-chip beats (KO's best day since 2009, SHW, BA) pulled money into staples, industrials, and value while memory melted down. And the rout is a *new* kind of threat: China's ChangXin flooding cheap DRAM compresses Korean-maker margins no matter how strong AI demand is — structural pressure that, unlike the capex worry, won't ease if hyperscaler guidance improves. With oil below $80 and the Fed deciding today, the tape shows where conviction lives: everywhere but crowded chips.
