Market Movers

S&P 500 — daily market movers

Macro backdrop

Risk appetite rebounded sharply, with all three indices higher. The Nasdaq jumped +2.26% to a record high — its best day since early August — the S&P 500 rose +1.49%, and the Dow gained +0.71%. The main driver was a sharp drop in oil prices, as Saudi Arabia restored pipeline capacity and crude exports recovered from August lows, while President Trump signaled willingness to meet Iran's president at the UN and set a summit with China this week — easing geopolitical risk premiums and inflation worries. Long-end rates also fell (the 10-year Treasury yield eased from around 5.00% to roughly 4.95%), together fueling buying in tech, semiconductors and growth stocks. Communication services and technology led, while energy lagged on the oil decline.

Top 10 gainers

  • 1. AKAM+12.33%
    Akamai
    CDN content delivery, cloud computing and cybersecurity services
    Surged on an analyst upgrade re-rating it as an AI-infrastructure and security play rather than legacy tech, reinforced by an ITV World Cup streaming (TrafficPeak) deal, and rode the broad growth rally.
  • 2. MRNA+12.27%
    Moderna
    mRNA vaccines and oncology vaccine research
    Extended the cancer-vaccine trade, with FDA vaccine approvals and oncology catalysts plus analyst upgrades piling on.
  • 3. INTC+12.14%
    Intel
    Chip design and foundry/semiconductor manufacturing
    A Wall Street upgrade backing its AI turnaround, improving pricing power and reported SK Hynix partnership talks lifted shares amid the chip rally.
  • 4. META+11.34%
    Meta Platforms
    Social media and digital advertising
    Wells Fargo raised its price target to $796 and AI optimism (its 'Muse' effort) built ahead of the Meta Connect event.
  • 5. WBD+10.79%
    Warner Bros. Discovery
    Film and TV studios, cable networks and streaming
    Media M&A optimism as Paramount Skydance antitrust settlement talks advanced, lifting the sector.
  • 6. AMD+9.95%
    Advanced Micro Devices
    CPUs, GPUs and AI accelerator chips
    Broad AI-chip demand drove a semiconductor-wide rally, pushing the stock to fresh record highs.
  • 7. QCOM+9.29%
    Qualcomm
    Mobile and wireless communications chips
    An Amazon deal, a 'port once' AI software stack and Snapdragon Summit anticipation added to the chip-sector strength.
  • 8. GDDY+7.50%
    GoDaddy
    Domain registration and web hosting for small businesses
    Rode the growth and software rally on falling yields, with no standalone company-specific catalyst on the day.
  • 9. APP+7.18%
    AppLovin
    Mobile ad-tech and AI-driven ad placement engine
    AI ad-tech strength as yields fell; no standalone single-name catalyst on the day.
  • 10. DDOG+6.58%
    Datadog
    Cloud observability and monitoring SaaS
    Software names benefited from lower yields and AI enthusiasm, rebounding with the broader market.

Common Themes

The gainers reflect a clear return of AI/tech risk appetite: the three big semiconductor names (INTC, AMD, QCOM) led, alongside mega-cap and growth software stocks (META, AKAM, APP, DDOG, GDDY), all benefiting from the twin tailwinds of falling oil and lower yields. Two non-tech names stood apart with their own catalysts — MRNA on continued cancer-vaccine momentum and WBD on media M&A optimism.

Top 10 losers

  • 1. MPC-5.30%
    Marathon Petroleum
    Oil refining and fuel marketing
    Crude's sharp drop hit refiners, which gave back gains after an outsized recent run.
  • 2. VLO-4.84%
    Valero Energy
    Crude oil refining and fuel production
    Another refiner pulling back alongside the fall in crude prices.
  • 3. UPS-4.35%
    United Parcel Service
    Parcel delivery and logistics
    Bank of America downgraded the stock to Sell and cut its price target.
  • 4. HPQ-4.22%
    HP Inc.
    Personal computers and printers
    Warned that the PC industry would decline by mid-single digits in 2027.
  • 5. PSX-4.17%
    Phillips 66
    Refining and midstream energy
    Fell with the refining/energy complex as oil prices retreated.
  • 6. CHTR-3.76%
    Charter Communications
    Cable broadband and pay-TV
    Weak cable subscriber trends and rotation out of value/defensive names pushed it toward a 52-week low.
  • 7. UNP-3.49%
    Union Pacific
    Freight rail transportation
    Rotation out of value/cyclical names, with no fresh single-stock catalyst on the day.
  • 8. CF-3.47%
    CF Industries
    Nitrogen fertilizer production
    Materials/value rotation and a softer energy complex weighed on the shares.
  • 9. COP-3.26%
    ConocoPhillips
    Oil and gas exploration and production
    The crude sell-off dragged on oil and gas producers.
  • 10. XOM-3.20%
    Exxon Mobil
    Integrated oil and gas major
    Fell with crude as an integrated oil and gas name.

Common Themes

The losers were dominated by energy: refiners and oil majors (MPC, VLO, PSX, COP, XOM) sold off broadly on the sharp drop in crude. The remainder reflected rotation out of value/defensive/cyclical names (CHTR, UNP, CF). Two were idiosyncratic single-name stories — UPS on a Bank of America downgrade to Sell, and HPQ on its 2027 PC market warning.

Overall read

Money rotated distinctly out of energy and value/defensive sectors and into technology, AI, semiconductors and growth. Falling oil and lower long-end yields simultaneously pressured energy and rate-sensitive value stocks while providing valuation fuel for high-multiple growth and chip names, pushing the Nasdaq to a record high. This was a macro-driven (oil and rates) risk-on rotation rather than an earnings-season sector split.
