What’s driving the moves
- AI and mega-cap tech remain the equity ballast. Chip and AI-linked buying helped keep indexes near highs even as rate sensitivity stayed elevated.
- Volatility cooled into the weekend. The VIX drop suggests investors are pricing less immediate downside risk despite geopolitical noise.
- Yields are still the spoiler. Reports continue to frame the 10-year yield above 5% as a ceiling on speculative risk appetite, especially for small caps and long-duration growth.
- Precious metals remain supported by geopolitical hedging. Gold and silver are still behaving like insurance assets while conflict risk and currency-debasement concerns stay in view.
