📰 Today’s Top 5 Stories

1

TOP 1 — Walmart Earnings Disappoint, Dragging Markets Lower

Walmart shares tumbled after its quarterly results missed expectations, becoming one of the worst performers on the Dow. The retail bellwether’s miss raised concerns about consumer spending health heading into the back-half of 2026. The Dow dropped over 700 points on the news.

2

TOP 2 — Treasury Yields Surge, Pressuring Rate-Sensitive Stocks

Bond yields resumed their uptrend, wiping out most of the prior day’s decline. Higher oil prices compounded the selling pressure. Rate-sensitive sectors including Technology and Utilities led declines as investors reassessed the Federal Reserve’s rate path.

3

TOP 3 — AI Infrastructure Spending Boom Continues Despite Volatility

Nebius (NBIS) shares surged 34% after earnings showcased rapidly expanding AI compute capacity, with per-MW pricing doubling versus prior year. Oracle confirmed plans to expand into Japanese nuclear power for AI data centers, reinforcing the long-term AI capex supercycle narrative.

4

TOP 4 — Cisco Systems Beats on Revenue & AI Network Demand

Cisco (CSCO) reported strong FY4Q26 results with revenue of $17.25B (+17.6% YoY). The company’s Scale-Across architecture is driving AI cluster interconnect upgrades from 1,000–2,000 ports to 12,000–32,000 ports. FY27 AI revenue guidance of $7.5B was issued.

5

TOP 5 — Tapestry (Coach Parent) Surges After Strong Earnings, Raises Dividend 16%

Tapestry (TPR) delivered FY26 Q4 revenue of $1.88B (+9.3% YoY) and non-GAAP EPS of $1.32 (+26.9%). Coach brand revenue grew 14%. The company raised its quarterly dividend by 16%, signaling management confidence in sustained demand for premium accessories globally.

🎯 Today’s Trading Strategy

Market Context: Risk-Off Day — Yields + Earnings Weakness

• Defensive posture recommended: With Walmart missing and yields rising, broad consumer discretionary and rate-sensitive tech exposure warrants caution. Consider trimming high-multiple names.
• AI infrastructure plays remain structurally intact: Despite the market decline, AI capex stories (Nebius, Cisco, Oracle) showed resilience. Dips in quality AI infrastructure names may offer entry points.
• Watch bond yields closely: The 10Y at 4.52% is approaching a key resistance zone. A break above 4.6% could trigger further equity selling, especially in growth/tech.
• Energy relative strength: Energy was the sole S&P sector posting gains (+0.38%). WTI stabilizing above $86 supports the sector near-term.

✅ Investor Checklist

🔍Monitor 10-Year Treasury yield — if it breaks above 4.6%, expect further pressure on growth stocks and tech valuations.

📊Track consumer spending indicators: Walmart’s miss may signal softening discretionary demand. Watch retail sector ETFs (XRT, XLY).

🤖AI infrastructure thesis remains intact: Cisco beat + Nebius surge = data center capex still accelerating. Consider quality AI supply-chain exposure on weakness.

🎯VIX at 16 — moderate, not alarming. Broad panic selling unlikely unless yields spike further or macro data deteriorates sharply.

🔥 Market Outlook & Risk Factors

Near-Term Outlook: Cautious — Yield + Earnings Crosscurrents

• Bull case: Earnings season winding down with strong Q2 results (+50.4% S&P 500 EPS growth per FactSet). AI capex supercycle shows no signs of slowdown. Fed likely to cut once in Q4.
• Bear case: Rising yields (10Y at 4.52%) compress multiples on high-P/E tech names. Walmart miss raises recession concerns for consumer sector. Dollar strength (DXY ~98.8) headwind for multinationals.
• Tariff risk: Trump administration signaling new drone import tariffs; “de minimis” exemption court ruling reinforces trade uncertainty overhang.
• Key watch levels: S&P 500 support at 7,550 (50-day MA region). Break below could accelerate selling toward 7,400. Resistance at 7,750–7,800 (recent highs).
• Next week catalyst: PMI Flash data (8-23 (Sun)), Fed speakers, and Jackson Hole-adjacent commentary on rate path.
