1 TOP STORY

U.S.-China Trade Optimism Sparks AI & Tech Rally

Renewed optimism over U.S.-China diplomatic talks is lifting AI and semiconductor stocks in premarket trading. Nasdaq 100 Futures surged +2.09%, with names like Nvidia, Meta, and Apple gaining meaningfully ahead of the open.

2 OIL & MACRO

WTI Crude Oil Drops ~2% — Relief for Inflation Outlook

Oil prices pulled back sharply as fears of a broader Iran supply disruption eased. WTI crude near $94/barrel. Lower energy costs reduce inflation pressure and improve consumer spending outlook, supporting equities broadly.

💡 Today's Trading Strategy

Bias: Cautiously Bullish
→ Futures rally (+1.4% to +2.1%) suggests a positive open, but watch for fade after initial gap
→ AI/Semiconductor names (NVDA, AMD, SMCI) likely to see early strength — watch for follow-through
→ Energy sector may underperform as oil weakens; consider underweighting XLE
→ Fear & Greed at 29 (Fear) — contrarian signal; long-term buyers may view this as entry zone
→ Keep stops tight; post-triple-witching Monday can be volatile in early hours

Risk Factors to Watch

⚠ Geopolitical Reversal: Any re-escalation in Iran — or surprise tariff news from U.S.-China talks — could rapidly reverse the morning rally
⚠ Post-Triple Witching Volatility: Last Friday was triple witching expiration; early-week rebalancing flows can be unpredictable
⚠ Treasury Yields: Watch 10Y yield; if it rises above 4.6%, it could pressure equity multiples in tech & growth
⚠ Fear & Greed at 29: While contrarian-bullish, it reflects underlying investor anxiety that could lead to quick sentiment reversals
⚠ Earnings Miss Risk: If AutoZone (AZO) or Micron (MU) disappoint, sector-wide selloffs are possible mid-week
