This Week's Read — August 17–21, 2026
Stocks fell this week as a chip-stock selloff and escalating US-Iran tensions overwhelmed a mostly strong round of retail earnings. The S&P 500 dropped 1.43% to 7,674.37. The Nasdaq Composite led losses, down 2.05% to 26,180.46. The Dow slipped 0.85% to 53,277.01, and the Russell 2000 fell 1.65%.
Chip stocks bore the brunt of it. Nvidia briefly shed as much as $153 billion in market value in a single session this week, AMD fell more than 4% and broke below the $500 level, and the PHLX Semiconductor Index posted its steepest three-day decline since March. Nvidia itself held roughly flat against the slide — a China thaw and its own August 26 earnings date are giving it some cover peers don't have.
Iran said it's going "fully offensive." The US refused Monday to extend the ceasefire reached in June, and Iran responded by vowing a more aggressive posture in the war; Treasury Secretary Scott Bessent said Washington would impose the "toughest sanctions in history" in response. Oil rose for a second straight week on the standoff — WTI added 2.77% — and the pain showed up at the pump here too: Vermont's statewide average climbed to $4.14 a gallon, within range of an August record.
Retail earnings gave a mixed but mostly reassuring read on the consumer. Home Depot beat Tuesday, with comparable sales up 1.7% — its best number since fiscal 2022 — and reaffirmed full-year guidance. Target beat big Wednesday: comparable sales rose 3.8% against a 2.4% consensus, and the company raised its full-year sales guidance. Walmart's Thursday report was softer at the core — US comparable sales grew 2.6%, the slowest pace in six years — but e-commerce grew 23% and the company still raised its full-year EPS guidance.
Gold jumped 5.61% to $4,665.60, its highest level in two months, as safe-haven demand built alongside the equity selloff. The VIX rose 6.18% to 15.13, and the 10-year Treasury yield ticked up to 4.74% — all consistent with a week where risk appetite cooled.
What's next: Nvidia reports Q2 earnings Wednesday, August 26 after the close, with analysts expecting around $91.8 billion in revenue — the next real test for the AI trade after this week's chip selloff. That same day brings a heavy data slate: the second estimate of Q2 GDP, July Personal Income & Spending (including the Fed's preferred PCE inflation gauge), and preliminary durable goods orders. Then the calendar shifts to Jackson Hole, where the Kansas City Fed's economic symposium runs August 27-29 and new Fed Chair Kevin Warsh delivers his first keynote as chair Friday morning — a signal markets will be parsing closely for where policy goes next.
