US Stocks open lower as Walmart's comparable sales miss — the weakest in four years — triggers a 6% premarket selloff in the world's largest retailer and puts the S&P 500 on track for its fifth straight losing session, even as Treasury yields pull back on the Department's emergency buyback expansion and Asian markets staged a broad rebound overnight on the same relief.

The S&P 500 slumped 0.3% at the open, Nasdaq-100 futures fell 0.4%, and Dow futures dropped nearly 300 points as Walmart's disappointing comparable sales data offset the yield relief from the Treasury's bond buyback announcement. Bloomberg noted the S&P 500 is now down 4% from its July 31 record closing high — its worst August stretch since 2015 — with the Nasdaq Composite on track to notch its fifth consecutive losing session. The major indexes fell below their 50-day moving averages this week for the first time since May, and all 11 S&P 500 sectors have declined over the past week with consumer discretionary taking the hardest fall.
Walmart (WMT) fell nearly 6% in premarket after beating Q2 EPS estimates but posting US same-store sales growth of just 2.6% — far below the 3.8% consensus — with average spending per transaction rising only 1.1% versus a 3.1% increase a year ago. Brian Jacobsen of Annex Wealth Management said bluntly: "For the consumer economy, this is like Nvidia posting a slowdown. Walmart has been winning the trade-down trade, but that tailwind may be fading." The miss puts the "resilient US consumer" thesis under its most direct pressure of the year and set a negative tone for the open even as the company maintained its full-year guidance.
The US Treasury Department announced it will more than double repurchases of 10-, 20-, and 30-year debt over the coming months — a direct intervention to cool the bond market after the 30-year Treasury yield surged to 5.336% on Tuesday, its highest since 2007, before reversing sharply. The move pulled the 30-year yield down to around 5.18% and the 10-year to approximately 4.63% ahead of Thursday's open, providing temporary relief for equities but stopping short of addressing the underlying inflation and geopolitical drivers of the yield surge. Wednesday's FOMC minutes from the July 28–29 meeting revealed the three dissenting members had argued strongly for an immediate hike, with their inflation concerns centered on energy costs tied to the Iran war — minutes that markets initially read as hawkish before the Treasury announcement reversed the yield move.
Alibaba (BABA) surged in premarket after reporting Q1 fiscal 2027 results that beat across every line — revenue growth accelerated, cloud computing revenue surged, and AI-related product revenue tripled year-over-year for the sixth straight quarter — with Alibaba becoming the first Chinese technology company to publicly disclose paying over 1 billion yuan in AI inference costs to third-party suppliers in a single quarter. The result drove Chinese tech names broadly higher in both Hong Kong and mainland trade. Deere & Company (DE) and Ross Stores (ROST) also report before today's open, alongside Coty (COTY) — which fell 18% after missing Q4 estimates and declining to provide fiscal 2027 guidance — and Wolfspeed (WOLF), which slipped 11.1% after a wider-than-expected quarterly loss. Weekly initial jobless claims, the Philadelphia Fed Index for August, and the Conference Board Leading Indicators for July all print at 8:30 a.m. and 10:00 a.m. ET respectively.
Brent crude held near $92 a barrel — on track for a fifth straight daily advance — as Washington stepped up economic pressure on Iran and there remained no clear path toward reopening the Strait of Hormuz. Iran's navy conducted what state media described as a live-fire exercise in the eastern Strait on Wednesday, a show of force that further complicated diplomatic efforts even as Oman continued mediation. The next major policy signal event for markets is now Friday's opening of the Federal Reserve's Jackson Hole Economic Symposium in Wyoming, where Chair Kevin Warsh is expected to speak — his most consequential public appearance since the July FOMC meeting, and the first chance investors will have to assess whether the FOMC minutes' hawkish tone reflects his own view or that of the three dissenters.
Japan's Nikkei 225 surged 791 points or 1.21% to close at 66,118 on Thursday, led by Sumitomo Metal Mining jumping 10.87%, Toho Zinc gaining 10.71%, and Kioxia climbing 5.7% — a broad-based recovery driven by the Treasury buyback news pulling yields lower and a US-Canada tariff reduction signal lifting automakers. Honda Motor jumped 4.7% to its highest level since July 2024 and Toyota rose 3.7% after Washington moved closer to reducing tariffs on Canadian-made vehicles from 25% to 15%. Sony gained 2.8%. The Topix added 0.8%.
South Korea's KOSPI surged on Thursday's open, recovering sharply from Wednesday's 5.4% crash that briefly triggered a program-selling sidecar halt — the rebound was driven by the same yield relief that lifted Japan, alongside Samsung Electronics and SK Hynix stabilizing after weeks of extraordinary volatility. The Investing.com Asia report noted "Asian stocks rebound as Treasury buybacks revive risk appetite; KOSPI surges." China's CSI 300 gained 0.2% and the Shanghai Composite rose 0.3% as Alibaba's results lifted tech sentiment broadly. Hong Kong's Hang Seng climbed 1.1%, with Alibaba up 2.3%, Xiaomi gaining 3.8%, Baidu advancing 3.5%, JD.com adding 2.8%, and Tencent also rising. Australia's S&P/ASX 200 was flat to modestly lower, having given back some of its prior record-high gains as iron ore softened and the energy sector remained under pressure from elevated oil prices.
