Key Points

01Moonshot AI's Kimi K3 model release triggered sharp intraday declines in large chip stocks and pushed the Philadelphia Semiconductor Index into a technical bear market.
02Renewed US-Iran hostilities and refinery/export-route reports lifted Brent and WTI, supporting energy outperformance and leaving XLE the only major US ETF higher.
03CPI, core CPI and PPI declines alongside modest retail gains and falling initial jobless claims reinforced a disinflationary yet solid-activity backdrop.
04A scrubbed Starship test flight and heavy put-option activity pushed SpaceX (SPCX)-linked SPCX lower, erasing over $1 trillion from its peak valuation.

Global Market Summary

US equities retreated as oil spiked and an AI-driven semiconductor selloff weighed on risk, with the S&P 500 (SPX) down 1.0%, the Nasdaq Composite (^IXIC) off 1.4%, and the Dow (DJIA) lower by 0.8%.

Asian indices also sold off, with NKY down 4.0%, HSI falling 1.8%, and 000001.SS lower by 3.0%, while in Europe FRA40 slipped 0.5% and DAX eased 0.3% but UKX gained 0.3% helped by strength in energy as Brent and WTI rallied.

Top Movers

Energy led sector performance as XLE rose 1.2% and was the only major US ETF higher, while XLC fell 1.8%, XLY declined 1.6%, VGT lost 1.0%, and XLP, XLF, XLV, XLI, VNQ, and XLU all closed modestly lower. Among single stocks, LCID jumped 13.9%, SLS gained 12.3%, ORKA rose 11.6%, DNTH advanced 10.8%, and COAG added 10.7%, while ISRG slumped 14.2%, CDNS dropped 9.5%, PENG fell 8.4%, SNPS lost 7.9%, and NFLX declined 7.3%.

Macro highlights

US data reinforced a disinflationary yet solid-activity backdrop as June headline CPI fell 0.4% month-over-month to 3.5% year-over-year, core CPI was flat month-over-month at 2.6% year-over-year, PPI declined 0.3% month-over-month, the retail control group rose 0.5% with headline retail sales up 0.2%, and initial jobless claims dropped to 208,000 versus 217,000 expected.

July Michigan Consumer Sentiment prelim improved to 54.4 from 49.5, beating the 51 consensus and 50.4 forecast, while markets assigned roughly 90% odds that the ECB and Fed would keep policy rates unchanged at upcoming meetings, still pricing only about a 12% chance of a July Fed hike from the current 3.50%–3.75% target and a 25 bp move later in 2026 as Fed hawks argued inflation remains too high.

Globally, Brent and WTI crude climbed to about $88.10 and $82.47, marking roughly 15–16% weekly gains amid renewed US–Iran hostilities, even as the dollar index DXY00 held near 100.77, 10-year and 2-year US Treasury yields hovered around 4.53% and 4.12%, gold and silver futures GCQ26 and SIU26 traded close to $4,018.8, and China’s Q2 GDP slowed to 4.3% from 5.0% with soft domestic demand keeping focus on potential PBOC support and BOJ inflation risks.

News that moved markets

Growth and tech sentiment weakened after Chinese startup Moonshot AI unveiled its Kimi K3 model, triggering sharp intraday declines in large chip stocks, pushing the Philadelphia Semiconductor Index into a technical bear market, and contributing to broad losses in the Nasdaq and S&P 500 (SPX).

SpaceX (SPCX)-linked shares SPCX dropped 5.4% to $123.99, trimming the company’s value to about $1.63 trillion and erasing more than $1 trillion from its peak as a Starship test flight was scrubbed and put-heavy options activity topped 500,000 contracts with roughly $350 million in premium.

Oil-related assets firmed as Brent for September settled up 4.6% at $88.10 and WTI for August rose 4.5% to $82.49, alongside a 75,996-contract build in long-only Brent positions to 357,154 and reports of US–Iran clashes, Iraqi pipeline and export-route deals, and an extended turnaround at Irving Oil’s Saint John refinery tightening refined-product expectations. BOXABL Inc. (BXBL) completed its business combination with FG Merger II Corp. at a $3.5 billion valuation, and Aura closed its acquisition of Qoria. On the announced side, Truecaller entered into an agreement to acquire US-based TextPlus Inc. and NNS agreed to acquire shares in OCI, while TXNM Energy and Blackstone Infrastructure extended their merger agreement. A PokerStars and Ladbrokes veteran also agreed to buy into Finnish news outlet Rahapelisanomat.
