Market Summary: Nasdaq Chip Stock Selloff

Key Developments

The Nasdaq Composite fell 1.4% on Tuesday, June 23, 2026, erasing approximately $680 billion in market value. The index is now down nearly 5% from its early June peak. The decline was driven primarily by a severe semiconductor sector rout, while other tech segments stabilized.

Sector Performance

The Philadelphia Semiconductor Index (SOX) plummeted 6.3%, led by memory chipmakers. Notable declines included:

• Micron (MU): -9% ahead of Wednesday earnings
• SanDisk: -12%
• Western Digital: -11%
• NVIDIA (NVDA): -2.6%, with market cap dropping below $5 trillion
• SOXX ETF: -7.30%

Conversely, mega-cap tech names showed resilience with bargain hunting:

• Microsoft: +2%
• Apple: +0.8%
• Alphabet: -0.4% (after Monday's 5% drop)

Market Implications

The selloff represents an unwinding of the concentrated chip trade that powered 2026's rally. Federal Reserve Chair Kevin Warsh's tighter monetary policy expectations are pressuring rate-sensitive growth stocks. The Nasdaq broke through its 50-day moving average at 25,676.57 for the first time since April 8, a significant technical development signaling potential trend reversal.

SpaceX briefly traded below its $150 IPO price, falling to $147.11 before recovering to $157, having lost over $600 billion in market cap since last week's peak.

Critical Catalyst

Micron's Wednesday after-hours earnings report could determine whether the selloff represents a buying opportunity or trend break, given AI-driven demand expectations. The Nasdaq's ability to close above its 50-day MA will be crucial for near-term direction.
