Post-close recap — 2026-08-18
How the day closed
- S&P 500: 7,691.76, -0.69% (-53.30)
- Nasdaq Composite: 26,289.71, -1.33% (-355.20)
- Dow: 53,343.40, -0.22% (-116.38)
- Russell 2000: 3,017.89, -1.30% (-39.65)
Stocks slid — led by chips and mega-cap tech — as a fresh push higher in long-end yields and firmer oil prices soured risk sentiment ahead of Jackson Hole later this week (Yahoo Finance, TheStreet).
Sectors & breadth
- Winners: Energy the lone bright spot, buoyed by a ~1% pop in crude on Iran/Strait-of-Hormuz risk headlines.
- Losers: Semis and communication services led the drop; consumer staples and financials also under pressure. Ten of eleven S&P sectors finished lower (Benzinga sectors).
- Breadth: Negative across both NYSE and Nasdaq; small caps underperformed alongside high-beta tech (Globe & Mail / Zacks).
Rates, FX, commodities, vol
- 10Y UST: ~4.70%, easing modestly off Monday's spike but still elevated.
- 2Y UST: ~4.19% (FRED DGS2).
- 30Y UST: ~5.29%, hovering near its highest since 2007 (TheStreet).
- DXY: ~99.6 area, little changed (Yahoo DXY).
- WTI: $84.42, +0.81% on Iran/Hormuz geopolitical risk.
- Gold: $4,389.50, -1.88% as real yields firmed (Yahoo Finance).
- VIX: 15.84, +4.28% — bid but still contained.
Drivers & headlines
- Long-end yields are the story. The 30Y sits near a 19-year high around 5.29%, and the back-up in duration risk is squeezing rate-sensitive equities and long-duration tech (TheStreet).
- Chip complex takes the hit. Nvidia off >2% and semis broadly lower on rekindled concern about hyperscaler AI-capex durability into 2027 (Yahoo Finance).
- Oil up on Iran risk. Crude firmed after fresh Trump-administration rhetoric around the Strait of Hormuz, supporting XLE while pressuring the rest of the tape (Yahoo Finance).
- Home Depot beats and reaffirms. HD delivered Q2 sales of $47.9B (+5.7%), adj EPS $4.92, comps +1.7% — the best comp print since fiscal Q3 2022 — and reaffirmed FY26 guidance; stock finished roughly flat, providing a small cushion for the Dow (Stock Titan, CNBC).
- Klarna (KLAR) -20% after trimming guidance — a warning shot on the consumer credit/BNPL cohort (Yahoo Finance).
After-hours
- Toll Brothers (TOL), Keysight (KEYS), and ZTO Express reported after the bell — options market priced ~5.7%, ~9.0%, and ~4.9% implied moves, respectively (TipRanks).
- Index futures were essentially flat post-close, with S&P and Nasdaq 100 pinned near unchanged and no macro tape-bomb after 4pm ET (Stock Analysis after-hours).
Setup for tomorrow
- FOMC minutes (July meeting) land Wednesday afternoon — market will parse for any hint about the pace of cuts and internal debate on the neutral rate against the backdrop of the 30Y at ~5.30%.
- Retail earnings continue (Target, TJX, Lowe's on deck this week) — HD's solid comp keeps the "consumer-still-spending" narrative alive but sets a higher bar.
- Jackson Hole kicks off later in the week; positioning into the keynote is likely to keep duration and USD choppy, and cap risk appetite until the tone is set.
