Stock Futures Reopen Tonight After Worst Week Since April — Volatility Is the Story

U.S. stock futures reopen Sunday night after the worst week for the S&P 500 since April 2025, with investors bracing for more volatility as questions over the AI trade, a new Democratic-controlled Congress, and Tuesday's inflation report collide. Futures had not yet opened when the Sunday preview was published, so there is no opening print to report yet — the story tonight is the setup, not a number.

What happened last week, in numbers

The Dow Jones Industrial Average closed down 0.9% for the week at 51,285.73, dropping 3.9% over its last two trading days, according to Dow Jones Market Data reported by Barron's. The S&P 500 fell 2.7% to 7,376.86 — its largest one-week point and percentage decline since the week ending April 4, 2025. The Nasdaq Composite dropped 3.4% to 24,579.42, its largest one-week point and percentage drop since the week ending October 16. An independent weekly wrap from GAMSG, citing YCharts data for November 2 to November 6, put the same moves at S&P 500 down 2.68%, Nasdaq down 3.37%, and Dow down 0.94% — matching Barron's figures within rounding.

Thursday did most of the damage. Barron's noted Thursday's rout was the biggest one-day percentage drop for stock indexes since April 4, 2025, the week after the so-called Liberation Day tariffs were announced. GAMSG put Thursday at S&P 500 down 4.4% and Nasdaq down about 5.5%, with technology leading all three averages lower. Friday steadied somewhat after a stronger-than-expected jobs report, but not enough to repair the week.

Why it's blowing up tonight

Sunday night is the first chance for traders to react with fresh positioning after a weekend of digesting three things at once. First, unease over the artificial-intelligence trade and future spending on AI data centers, now under an incoming Democratic-controlled Congress and Democratic-led state governments, as Barron's put it. Second, skepticism that has been building for months: Fiduciary Capital Management, in a Saturday note cited by Barron's, said the Nasdaq essentially made all its 2026 gains in April and May — up more than 27% in those two months — and was down 8.1% from June 1 to November 1. The firm said conditions for a broad equity bounce are not on the near-term horizon, and doubted any meaningful recovery in sentiment soon given the scale of money, debt, and spending promises committed to the AI trade.

Third, rates. Markets see the Federal Reserve raising interest rates again in December, Barron's reported, with solid growth and inflation persistently well above target described as a recipe for further hikes. That makes Tuesday's data more than a routine release.

What's next

The futures open itself is only an early signal — overnight moves can reverse before Monday's opening bell, and a quiet Sunday print would not settle whether Thursday was a steeper step in a broad rerating of AI prospects or a capitulation, as Fiduciary framed it. The harder tests come during the week: Tuesday's CPI will show whether inflation is still running well above target heading into the Fed's December meeting, Friday's PPI adds the producer-side view, and Thursday's reports from Cisco and Applied Materials give a fresh read on AI infrastructure demand from inside the sector itself. Until those land, volatility — not direction — is the consensus expectation for tonight.
