Direct answer
Headlines on Fed policy, earnings, or macro data drive SPY. Focus on breadth and liquidity as leading indicators. Ignore noise unless it shifts sentiment.
Market context before reacting
SPY reflects S&P 500 breadth and macro confidence. Liquidity and earnings revisions are key. Watch for divergence between SPY and underlying breadth.
Headlines that usually matter

Stable inflation
If a headline materially changes expectations around stable inflation, it can genuinely reprice S&P 500 ETF.
Policy accommodation

Headlines that are often noise
- Recycled commentary that does not change expectations
- One-off social media reactions without broad market confirmation
- Low-signal headlines that do not affect the core thesis or positioning
Best workflow after a headline
