📰 Today’s Top 5 Stories

1 US-Iran Tensions Spike Oil & Bond Yields

Renewed US-Iran war concerns drove oil prices sharply higher and sent the 30-year Treasury yield to its highest level since 2007. The risk-off mood weighed on all major equity indices Monday, with energy stocks outperforming while rate-sensitive sectors lagged.

2 PPI Flat in July — Rate Hike Odds Dim

US producer prices came in unchanged for July (vs. expected +0.2%), dragging the annual rate from 5.5% to 4.7%. September rate hike odds declined further, though rising energy prices and Treasury yields complicate the Fed’s path forward.

3 Cisco (CSCO) Beats on AI Networking Surge

Cisco reported FY4Q26 revenue of $17.25B (+17.6% YoY), driven by its Scale-Across AI networking platform. FY27 guidance revenue $72.2–73.4B (+15%). AI revenue FY27 target $7.5B, with 80% backlog coverage. Stock fell 8.4% as market rotated despite the beat.

4 NVIDIA GB300 Supply Constraints Spark Debate

Reports surfaced that NVIDIA’s GB300 GPU shipments may be constrained in H2 2026 as hyperscaler demand accelerates. AI capex from major cloud providers continues to surge, with analysts noting FY27 AI infrastructure spend could top $1 trillion. Price target reiterated at $275.

5 Tapestry (TPR) Surges 14%+ on Strong Coach Brand Results

Tapestry reported FY26 Q4 revenue of $1.88B (+9.3% YoY), with non-GAAP EPS of $1.32 (+26.9% YoY). Coach brand revenue rose 14%, driven by strong international demand. FY27 guidance revenue $8.4–8.5B, EPS $7.80–7.90. Stock surged >6% after-hours then gave back gains in Monday trading (−16.5%).

🎯 Today’s Trading Strategy

  • Energy overweight: Oil surge favors XLE/CVX/XOM as Iran risk premium stays elevated
  • Avoid long-duration bonds: 30-yr yield at 19-yr high signals continued pressure on rate-sensitive sectors (utilities, REITs)
  • AI infrastructure remains core: Networking + power management plays (CSCO, Vertiv, Cisco’s Silicon One) benefit from scale-out demand
  • Watch defensive rotation: PPI cooldown supports consumer staples and healthcare as rate hike fears ease
  • CPI watch (Tue 8:30 AM ET): Hot print could accelerate yield surge; cool print supports risk-on bounce

  • Monitor 30-yr yield above 5%: sustained levels hurt mortgage REITs, utilities, and long-duration growth stocks

Market Outlook

💡 Market Outlook & Risk Factors

Bull Case: Flat PPI supports disinflation narrative → Fed on hold → soft landing intact. AI spending cycle accelerating (Cisco, NVIDIA, Microsoft all confirm robust demand). S&P 500 remains near record highs with strong earnings breadth (87% beat rate, ~30% YoY growth).

Bear Case: 30-yr yield at 19-yr high & WTI surging = stagflation risk. US-Iran escalation could spike oil above $90+, reigniting CPI. Bond market volatility (MOVE ~110) may spill into equities.

Key Watch: Tuesday CPI print is the week’s most critical data point — a hot reading (>+0.3% MoM) would likely pressure equities and push yields higher, while an in-line or cool reading supports risk assets.
