ISM Manufacturing PMI & JOLTS Job Openings Due at 10 AM ET

Bond Selloff Deepens — 10-Year Treasury Yield Climbs on Inflation Fears

Rising oil prices are reigniting inflation concerns, driving a bond selloff. The 10-year Treasury yield climbed, increasing borrowing costs and adding pressure to growth equities. Small-cap Russell 2000 is the biggest casualty, down 1.92% at the prior close.

🎯 Today’s Trading Strategy

Defensive posture recommended. Oil-driven inflation fears combined with geopolitical escalation call for caution. Consider:
→ Energy overweight: XOM, CVX, HAL benefit directly from oil spike
→ Reduce growth exposure: High-beta tech sensitive to rising yields
→ Wait for 10 AM data: ISM & JOLTS prints will set the intraday tone
→ PANW binary event: Earnings after-close — high IV, consider neutral options strategies
→ Safe havens: DXY strength and gold may continue as Hormuz risk premium persists
