The S&P 500 gained 0.22% to 769.09 and the Russell 2000 led at +0.49% to 301.72, while the Nasdaq (NDAQ) 100 slipped 0.24% to 716.03 as Technology dropped 1.05%. The dominant driver was the Treasury's doubling of its long-bond buyback program, which pulled yields from 20-month highs, weakened the dollar, and sent gold up 3.7% to roughly $4,500. Health Care surged 3.53%, almost entirely powered by Moderna (MRNA) and Merck (MRK) after their combination cancer therapy posted positive Phase 3 melanoma data, with MRNA up as much as 177% in its best day ever. Fed minutes released at 2:00 PM showed growing official support for a rate hike if inflation does not cool, a hawkish undercurrent that likely capped Tech and Financials (-0.61%). The Treasury buyback's dollar-negative, yield-suppressing effect and the Fed minutes' hawkish signal both carry directly into Thursday.

Tomorrow

Thursday, Aug 20, 2026

What is scheduled, with ET times. Not a forecast of how it lands.

No scheduled economic data prints Thursday. Deere (DE) and Walmart (WMT) both report before the open (pre-9:30 AM ET), front-loading event risk to the open. WMT is a consumer bellwether whose guidance will be read against today's soft prints from TJX Companies (TJX) (-2.8% on weak Q3 guidance) and Lowe's (LOW) (lowered guidance). Watch whether DE's report extends or reverses today's Industrials weakness (-0.86%). The next hard macro catalysts are GDP and PCE inflation, both at 8:30 AM on August 26.

Session structure

How the calendar shapes each holding period. Descriptive only: not advice, and not a recommendation to trade anything.

⚡ ScalpWith Deere and Walmart (WMT) both reporting before the 9:30 AM ET open Thursday and no macro data scheduled, volatility is concentrated in the pre-market and at the open. Conditions in consumer and industrial names typically feature wider bid-ask spreads around earnings-driven gaps. VIX closed at 14.89, down from 15.84.
☀️ Day tradeThursday's session structure is shaped almost entirely by the WMT and DE pre-open reports. Consumer Staples, Consumer Discretionary, and Industrials are the sectors most directly in focus at the open. Health Care's 3.53% surge Wednesday, led by an MRNA event, creates a reference point for whether that sector holds or gives back ground intraday.
🌊 SwingSeven of eleven sectors closed higher Wednesday and VIX fell to 14.89 from 15.84, reflecting a broadly improving near-term risk backdrop. However, the Fed minutes released at 2:00 PM Wednesday flagged growing support for a rate hike if inflation does not cool, and GDP and PCE inflation both print at 8:30 AM on August 26, sitting inside any multi-day position opened this week.
🌲 Long termThe Federal Reserve minutes from the July 28-29 meeting, showing officials more open to rate hikes if inflation stays elevated, are the only Wednesday development with potential long-duration portfolio relevance. The Treasury's long-bond buyback program affected near-term yields and the dollar. PCE inflation on August 26 is the next scheduled data point relevant to the rate and inflation outlook.
