Key Highlights

● The SPDR S&P 500 ETF slipped 0.37% on the day of the hot CPI report.

● The index rallied 1.31% to 7,619.38 a day later.

● It sits within 2.6% of its record.

● The bigger effect may be on the road ahead.

When the October Consumer Price Index came in hotter than expected on Tuesday, the S&P 500's immediate reaction was mild: the SPDR S&P 500 ETF slipped 0.37% that day. A day later, the index rallied 1.31% to 7,619.38, within 2.6% of its record. The bigger effect of the report may be on the road ahead, as it reshaped expectations for interest rates through the end of the year.

Consumer prices rose 0.4% on a seasonally adjusted monthly basis in October, and core prices increased 0.3%. Within days, markets moved to price about a 90% chance of a quarter-point Fed hike at the December 8-9 meeting, according to CME FedWatch.

What the report changed

Before the release, the debate over the Fed's next move was more open. Afterward, officials sounded markedly hawkish. Chicago Fed President Austan Goolsbee called the data "borderline disturbing," Dallas Fed President Lorie Logan said she sees two more quarter-point hikes, and Philadelphia Fed President Anna Paulson said "further gradual tightening seems appropriate." Goldman Sachs and UBS now expect hikes in December and March.

That turns the final weeks of the year into a period of tightening rather than steady policy. The 10-year Treasury Yield was near 5% Thursday, and the dollar index stood near a 19-month high. Both can weigh on stock valuations and corporate earnings.

For the S&P 500, the key question is whether Earnings growth can keep offsetting higher rates. So far, it largely has. Apple (NASDAQ:AAPL) finished at a record $355.63 on Wednesday and is up 31.1% this year. Wednesday's advance was broad, with energy, industrials and financials joining tech.

The year-end calendar

Several scheduled events will test the market before the Fed meets. Nvidia (NASDAQ:NVDA) reports fiscal third-quarter results November 17 after the bell, a release clouded by reports that its board was weighing whether to remove chief executive Jensen Huang. Those allegations have not been independently confirmed, and the stock was down roughly 6% to 7% premarket Thursday.

Retailers follow. Home Depot (NYSE:HD) and Disney report November 17 before the open, Lowe's (NYSE:LOW) and Target on November 18, and Walmart (NASDAQ:WMT) on November 19. Those results will show how consumers are handling higher prices; the NRF/CNBC retail monitor already showed October retail sales rising just 0.2% from September, the slowest since November 2025.

Anthropic's planned Nasdaq debut on November 19 could also draw attention and capital, with pricing set for November 18.

There is a more optimistic reading. A hike that is fully expected may not disrupt the market much. Stocks rallied strongly after the November 3 midterm elections, with Amazon (NASDAQ:AMZN) up 7% and Apple and Microsoft (NASDAQ:MSFT) up 5% on November 4, showing that investors have been willing to buy despite rising rates. Some economists also argue that slowing consumer spending will cool Inflation on its own, limiting how far the Fed needs to go.

On the other hand, the risk of a bigger move is not zero. One market analyst said "the possibility of a 50-basis-point increase in December has also entered the conversation." A sharper tightening path could pressure valuations more than currently expected.

What to Watch Next on S&P 500 Outlook

Near term, Friday's producer price index, expected to rise 0.4% on the month, will show whether wholesale prices confirm the CPI signal. Thursday's jobless claims at 8:30 a.m. ET and a slate of Fed speakers, from Governor Michael Barr at 10 a.m. to New York Fed President John Williams at 6:30 p.m. ET, will add detail. Fed officials Susan Collins and Michelle Bowman speak Friday as well.
