The essence of today's semiconductor collapse is not Broadcom's disappointment alone. INTC -11.28%, AMD -10.86%, and NVDA -6.2% each fell for different reasons — yet all crashed simultaneously.

📊 Top Movers
🧭 Sector Performance
🇰🇷 Korean Investor Perspective
USD/KRW rose +2.96 won (mild USD strength). QQQ's -4.18% USD loss deepens to approximately -4.37% in KRW terms after the currency impact. Korean retail investors with SOXL exposure saw catastrophic losses — SOXL was down roughly -30% on the day. Today's decline was one of the steepest single-session losses for Korean 'seohak gaeam' (overseas retail investors) in recent memory. Holding leveraged ETFs through earnings volatility carries extreme tail risk.
📊 Market Overview
On Friday, June 5, US markets were devastated by a broad semiconductor meltdown. The Nasdaq fell -4.18% — its worst single-session decline since the April 2025 tariff shock. The S&P 500 dropped -2.64%, and the Dow fell 695 pts (-1.35%). The Philadelphia Semiconductor Index (SOX) plunged -10.3%, the largest single-day drop since the March 2020 COVID panic.
🔑 Key Issues
1. Broadcom AI Guidance Shock — Semiconductor Selloff Trigger Broadcom's Q3 AI chip revenue guidance of $16B fell 7% short of the $17.2B consensus. CEO Hock Tan acknowledged that some AI chip business with Alphabet (Google) had shifted to Taiwan's MediaTek. AVGO fell -11.28%, triggering contagion across the entire semiconductor sector.
2. Philadelphia Semiconductor Index (SOX) -10.3% INTC -11.28%, AMD -10.86%, MU -6.30%, NVDA -6.20%, ARM -8.5%. The SOXX ETF posted its worst session since March 2020. By market cap, the semiconductor sector shed approximately $1.3 trillion in a single day.
3. Strong May Jobs Report — Rate-Cut Expectations Plunge May nonfarm payrolls came in at 172,000, well above the 150,000 consensus. Average hourly earnings rose 4.1% YoY, keeping inflation concerns elevated. The 10-year Treasury yield jumped 9 bps to 4.54%, and the probability of a September Fed rate cut fell from 62% to 41%.
4. Defensive Stocks Outperform Consumer staples (XLP) +1.71%, utilities (XLU) +1.40%, healthcare (XLV) +0.60% all held up. MCD +2.61%, KO +1.80%, PG +1.40%, DUK +1.97% attracted risk-off flows.
5. Weekly Recap — AI Mega-Cap Valuation Re-Assessment Semiconductor names averaged >15% weekly declines. The market began questioning who actually benefits from AI infrastructure spending. The narrative shifted: "AI capex doesn't have to accrue exclusively to chip makers."

🇰🇷 Korean Investor Perspective
USD/KRW rose +2.96 won (mild USD strength). QQQ's -4.18% USD loss deepens to approximately -4.37% in KRW terms. SOXL holders saw catastrophic losses (~-30% on the day). Today was one of the steepest single-session losses for Korean overseas retail investors in recent memory. Holding leveraged ETFs through earnings volatility carries extreme tail risk.
⚠️ Investor Cautions
SOX's -10.3% in a single session underscores the speed at which AI capex sentiment can reverse. SOXL and leveraged semiconductor ETFs are not suitable for holding through earnings uncertainty. The strong NFP data has effectively priced out 2026 Fed rate cuts.
👁 Tomorrow's Watch Points
- Is SOX's selloff capitulation or the start of a re-rating?
- Watch for weekend headlines on Broadcom-Google AI supply chain developments
- Any Fed commentary over the weekend on the jobs/inflation outlook
