S&P 500 — daily market movers
Macro backdrop
All three major indices fell. The Nasdaq slumped about 2.14%, the S&P 500 fell about 1.09%, and the Dow held up better at about -0.34%. The selloff was driven by worries over the financing and debt sustainability behind the AI boom — data-center upstart CoreWeave came under pressure from its heavy debt load, sparking a global rout in AI stocks — compounded by a hotter-than-expected CPI print that lifted Treasury yields and weighed on richly-valued growth names, with the tech sector down more than 3% on the day. At the same time, global oil prices surged on rising Iran-related geopolitical risk (Brent testing roughly $110 intraday), making energy the day's standout gainer and lifting defense stocks.

|---|---|---|---|---|
| 1 | TRGP | Targa Resources Natural gas gathering/processing and NGL midstream infrastructure across the US | +4.37% | Rallied with the energy sector (the day's best, up about 2.5%) as crude prices spiked; midstream gas/NGL names benefited from the broad rotation into energy. |

| 3 | EOG | EOG Resources US shale crude oil and natural gas exploration and production | +4.23% | Rose with the oil spike as money rotated into energy away from high-valuation tech. |
| 4 | KMI | Kinder Morgan Natural gas pipelines and energy storage and transport infrastructure | +4.20% | Gained as the energy complex strengthened on the oil rally; pipeline midstream benefited from the sector-wide bid. |
| 5 | APA | APA Corp Oil and gas exploration and production in the US and Egypt | +4.07% | Climbed on the sharp jump in crude prices, a direct tailwind for E&P producers. |
| 6 | NOC | Northrop Grumman Aerospace and defense systems, missiles, and military aircraft | +4.05% | Advanced after President Trump said the US may strike Iranian nuclear facilities again, lifting defense stocks. |
| 7 | RTX | RTX Corp Aerospace and defense; jet engines, missiles, and defense electronics | +3.73% | Rose as escalating Iran tensions boosted expectations for defense orders. |
| 8 | LMT | Lockheed Martin Defense contractor making fighter jets, missiles, and military systems | +3.65% | Gained on the geopolitical escalation around Iran, drawing money into defense names. |
| 9 | EQT | EQT Corp Largest US natural gas producer, focused on the Appalachian basin | +3.53% | Advanced alongside the stronger natural gas and broader energy complex. |
| 10 | NI | NiSource Regulated natural gas and electric utility across the US Midwest | +3.47% | Rose as defensive utilities attracted rotation out of growth and tech. |

Common Themes
Nine of the ten gainers are energy or defense names. Crude's surge — driven by rising Iran-related geopolitical risk — made energy the day's best-performing sector (up about 2.5%), while Trump's comments about potentially striking Iran again lifted defense contractors (NOC, RTX, LMT). A defensive utility (NI) rounds out a clear rotation into energy, defense and value as money fled high-valuation tech.

Common Themes
The losers are almost uniformly high-valuation tech/AI names: AI hardware (SMCI, FLEX, STX), AI and SaaS software (PLTR, DDOG) and cybersecurity (PANW, FTNT, CRWD), plus optical-networking play Coherent. The trigger was mounting worry over AI financing and debt — data-center upstart CoreWeave's heavy debt load sparked a global AI-stock rout — compounded by a hot CPI print lifting yields; the tech sector fell more than 3%. Moderna was the lone non-tech loser, trimmed ahead of vaccine-trial data.
Overall read
A textbook risk-off rotation: capital fled richly-valued, financing-dependent AI and growth names and flowed into energy (on the oil spike), defense (on Iran escalation) and defensive utilities. Doubts about AI 'bubble' and debt sustainability deepened, with the Nasdaq (about -2.14%) sharply underperforming the Dow (about -0.34%) — a stark growth-versus-value split.
