Market Summary
U.S. equities remained under broad pressure at midday Monday as a fresh flare-up in U.S.-Iran hostilities sent crude oil sharply higher and rattled sentiment to open the holiday-shortened week. As of 12:00 ET, the S&P 500 traded at 7670.20, down 41.56 points (-0.54%), the Dow Jones Industrial Average fell 341.49 points (-0.64%) to 53218.50, and the Nasdaq Composite declined 131.59 points (-0.50%) to 26291.88. All three major averages were hovering near session lows heading into midday before paring losses modestly on resilience in select technology names.
The primary catalyst was a jump in oil prices after the U.S. and Iran traded military strikes over the weekend, with President Trump raising the specter of further escalation around Kharg Island. WTI crude touched as high as $86.51-$86.63/bbl, up roughly 2.6%-3.9% on the session, feeding inflation concerns that pushed Treasury yields to fresh 2026 highs across the belly and long end of the curve. That combination of rising oil and higher yields weighed on nine of eleven S&P 500 sectors, with only Energy showing a clear gain and Information Technology trading roughly flat.
Beneath the index-level weakness, stock-specific developments dominated the tape. CrowdStrike (+3.80%) extended its post-earnings rally on a wave of AI-platform announcements, Aon (-7.07%) slid on the size and financing of its $17.0 billion USI Insurance Services acquisition, and Take-Two (-6.88%) dropped following leaked footage of Grand Theft Auto 6. Small- and mid-cap stocks underperformed the majors, with the Russell 2000 down roughly 0.9%, underscoring a continuation of the narrow, mega-cap-led leadership that characterized the prior week.

Key Earnings & Movers
- CrowdStrike (CRWD) — $226.69, +$8.29 (+3.80%): Extending post-earnings rally on expansion of Project QuiltWorks and launch of Falcon IQ, integrating telemetry from 12 additional security vendors and 50+ Charlotte AI agents with NVIDIA Nemotron models.
- NVIDIA (NVDA) — $219.19, +$1.64 (+0.75%): Holding gains after last week’s earnings surge even as broader semiconductors lagged (PHLX Semiconductor Index -0.2%).
- Aon (AON) — $330.29, -$25.11 (-7.07%): Sliding on $17.0 billion cash acquisition of USI Insurance Services from KKR; deal funded with new debt, no near-term buybacks, EPS accretion not expected until 2028.
- Take-Two Interactive (TTWO) — $219.19, -$16.20 (-6.88%): Pressured by leaked footage of upcoming Grand Theft Auto 6.
- Eli Lilly (LLY) — $1,152.04, -$22.56 (-1.92%): Lower despite agreeing to acquire Merida Biosciences for up to $2.875 billion and reporting encouraging Phase 3b Taltz/Zepbound combination data.
- Edison International (EIX) — $53.90, -$16.27 (-23.19%): Sharply lower after California lawmakers advanced a narrower wildfire package omitting proposed insurer-recovery limits.
- PG&E (PCG) — $13.42, -$3.18 (-19.16%): Same wildfire-legislation catalyst as EIX.
- Alphabet (GOOG) — $334.44, -$8.44 (-2.46%): Weighing on communication services sector.
- Science Applications International (SAIC) — Rallying after a broad Q2 beat; raised FY27 adjusted EPS guidance to $10.65-$10.75 (from $9.90-$10.10) and revenue guidance to $7.2-$7.3 billion.
Stock Spotlight
CrowdStrike (CRWD) is the standout mover of the session, rallying 3.80% to $226.69 and extending its post-earnings advance. The gains are being driven by a broad set of product and partnership announcements that reinforce the narrative of Falcon evolving from a pure endpoint-security tool into a full AI-era cybersecurity operating platform. The centerpiece is the expanded Project QuiltWorks initiative alongside the launch of Falcon IQ, which combines real-time telemetry from 12 additional security vendors with more than 50 Charlotte AI agents and NVIDIA’s Nemotron models to automate risk assessment, prioritization, and remediation — while potentially activating additional Falcon modules and partner services.
The move is notable not just for CrowdStrike’s own strength but for its read-through to the broader technology tape: it is helping anchor the Information Technology sector near flat territory even as nine of eleven S&P 500 sectors trade lower on the day. NVIDIA is also participating, up 0.75% to $219.19, holding onto gains from last week’s earnings surge even as the PHLX Semiconductor Index slips 0.2%, underscoring a continued bifurcation between AI-infrastructure software/platform plays and the broader chip complex.
Bond Market & Treasuries
Treasuries sold off sharply through the morning, with the long end sliding to fresh highs for the year. As of the 10:21 ET update:
- 2-yr: 4.34% (-1 bp)
- 3-yr: 4.40% (unchanged)
- 5-yr: 4.50% (+2 bps)
- 10-yr: 4.76% (+4 bps), price -6/32
- 30-yr: 5.26% (+6 bps)
Yields on 3s, 5s, 7s, and 10s hit fresh 2026 highs, with the 2-year on the verge of doing the same. The move follows an overnight advance in crude oil tied to the U.S.-Iran conflict, feeding inflation concerns just days after Fed Chair Kevin Warsh’s hawkish Jackson Hole remarks lifted September rate-hike odds to 60% from 40%. Currency markets showed USD/JPY at 159.79 and EUR/USD at 1.1603.
