The stock market surged today as cooler-than-expected inflation data fueled optimism for a Federal Reserve rate cut. The S&P 500 climbed higher, notching its fourth consecutive day of gains after the Personal Consumption Expenditures (PCE) report showed inflation moderating. Investors are now betting heavily on interest rate relief heading into the Fed’s December meeting.
🔥 Quick Facts
- Core PCE inflation fell to 2.8% annually in September, below the expected 2.9%

The delayed September PCE report, released today on December 5, 2025, delivered welcome news for equity markets. The core PCE price index, which strips out volatile food and energy costs, came in at 2.8% year-over-year, down from expectations of 2.9%. The headline PCE also increased only 0.3% monthly, keeping annual inflation at 2.8% as well.
This softer reading on the Fed’s preferred inflation gauge immediately energized investors. The data suggested that persistent inflation pressures are finally cooling, making the case stronger for the Federal Reserve to lower borrowing costs. Stocks interpreted the report as a green light for policy accommodation ahead of the central bank’s December 10 decision.

The stock market’s reaction was swift and powerful. S&P 500 futures jumped following the inflation data release, with the index heading toward record territory as trading concluded today. The stronger performance reflected investor confidence that the Federal Reserve will indeed cut rates by 25 basis points next week.
According to market pricing from the CME FedWatch tool, odds of a December rate cut surged to approximately 87-89% after today’s PCE report and stronger consumer sentiment data. This represents a significant increase from earlier estimates and signals that traders believe inflation has cooled enough to warrant the Fed taking its foot off the rate-hike brake.

How Today’s Rally Positions Investors for Next Week
Today’s stock market rise represents investor confidence that the Federal Reserve can afford to cut rates without reigniting inflation concerns. The S&P 500‘s four-day winning streak, coupled with advances in the Dow Jones and Nasdaq, suggests broad-based optimism about easier monetary policy ahead. Bond markets also reacted, with Treasury yields moving higher as investors repriced expectations for future rate cuts.
Markets are now focused on next week’s Federal Reserve meeting on December 10. Beyond the rate decision itself, investors are closely watching what Fed Chairman Jerome Powell says in the post-meeting press conference about the future path of interest rates. The signal will help determine whether a single quarter-point cut marks the beginning of a broader easing cycle or remains an isolated move.
What Does This Inflation Report Mean for Your Portfolio?
The cooler PCE inflation data combined with today’s market surge suggests that equity investors who were anxious about rate risks can breathe easier for now. Sectors that suffered during the rate-hike cycle, particularly growth stocks and technology names, stand to benefit from lower borrowing costs. Bond investors also saw yields surge higher on rate-cut expectations, signaling potential price improvements for fixed-income portfolios.
However, investors should remember that a single positive inflation reading doesn’t guarantee permanent rate cuts. The Federal Reserve remains data-dependent, meaning future economic releases could shift the trajectory. Markets are pricing in about 25 basis points of cuts by yearend, but the exact pace and magnitude of rate reductions will depend on upcoming labor data, consumer spending trends, and other economic indicators through the end of 2025 and into 2026.
