Deep DiveToday's Market Movers
S&P 500 posts its best day since April as tech rebounds
What Happened
The S&P 500 rose 2.35% to 7,549.94 on Monday, its best day since April 8, as buyers returned to tech stocks after last week's selloff. The Nasdaq Composite gained 2.74% to 25,253.14, and the Dow Jones Industrial Average added 1,104.02 points, or 2.15%, to 52,389.75. Small companies did even better, with the Russell 2000 up about 3.1%, and every one of the 11 S&P 500 sectors finished higher.
Why It Matters
The rally erased part of the damage from last Thursday, when the Nasdaq fell 5.5% into a correction (a drop of 10% or more from a high) on worries about AI regulation. See our guide to what a stock market correction is for more.

Oil sharply lower, helping stocks
Oil plunges as Trump plays down new strikes on Iran
What Happened
Brent crude futures settled down $5.75, or 5.85%, at $92.57 a barrel on Monday after President Trump said new strikes on Iran were unlikely while talks continue. US West Texas Intermediate settled down $3.98, or 4.38%, at $86.85. Brent kept falling after the close and was near $91 on Tuesday, following a 16% drop last week, its steepest weekly fall since the start of the COVID-19 pandemic.
Why It Matters
Cheaper oil lowers fuel costs and eases pressure on inflation, which is a main worry for the Federal Reserve. Reuters also noted signs of extra supply, with a surplus of about 1.4 million barrels a day in October, according to JPMorgan. For the mechanics, see why oil falls and stocks rise when war fears ease.

Nvidia falls after board opens probe into CEO Jensen Huang
What Happened
Nvidia shares closed down 4.27% at $178.67 on Monday, their lowest close since April 7, after the company's board opened an independent investigation into CEO Jensen Huang. The probe follows reports of his relationship with a woman US officials believe is a Chinese spy. The board said it has no reason to believe national security or company secrets were compromised, and Huang said he will cooperate. Shares fell as much as 7.3% at the open.
Why It Matters
Nvidia is one of the largest stocks in the market, so its drop weighs on index gains. Other chipmakers still rallied, which shows buyers were focused on the wider tech rebound. For background on the debate around AI stocks, read Are We in Another AI Bubble?

Treasury yields hold near two-month lows ahead of CPI and a $125 billion auction week
What Happened
The 10-year Treasury yield held near 4.86% on Monday, close to a two-month low and about 40 basis points below early October levels. The 2-year yield was about 4.54% and the 30-year about 5.26%. The Treasury will sell $125 billion of notes and bonds this week, including $42 billion of 10-year notes today and $25 billion of 30-year bonds on Thursday.
Why It Matters
Yields set borrowing costs for mortgages and companies. Large auctions can push yields up if buyers want a better payoff to absorb the supply. Our explainer on bond yield shows why.

October CPI due this morning with a December Fed rate hike in focus
What Happened
The Bureau of Labor Statistics releases the October consumer price index at 8:30 a.m. ET today, with forecasts of a 0.3% rise for overall prices and 0.2% for core prices, which exclude food and energy. September's overall reading was 0.60%, and gasoline prices fell more than 4% in October. No annual rate will be published because of data gaps left by last year's government shutdown. Last Friday's jobs report showed 165,000 jobs added against a forecast of 65,000, with unemployment at 4.1%.
Why It Matters
Strong jobs and sticky inflation are why traders expect the Fed to raise rates again in December. A reading above or below forecast can move stocks and yields quickly. Learn more about CPI, the Consumer Price Index.
Market Impact
Equities
Index futures sensitive to the inflation print

Traders see about an 81% chance of a December hike

Dollar sensitive to the CPI result

Lower gasoline helped October prices
