Markets Digest the Path of Interest Rates & the Next Phase of the AI Cycle

Monthly Market Summary - December 1, 2025

The S&P 500 Index returned +0.2% in November, its seventh consecutive monthly gain. Large Cap Growth declined -1.8% as AI-related names came under pressure, while Large Cap Value rose +2.7%. The Russell 2000 and the Dow Jones Index both outperformed the S&P 500 as mega-cap tech stocks weighed down the index.
Health Care led all S&P 500 sectors with a +9.3% return. Eight of the eleven S&P 500 sectors outperformed the index, while the Technology, Consumer Discretionary, and Industrials sectors each traded lower and underperformed the index.
Bonds traded higher as Treasury yields ended the month lower despite intra-month volatility tied to uncertainty around a December rate cut. The U.S. Bond Aggregate gained +0.6%, increasing its year-to-date return to +7.5%. Investment-grade bonds matched the Aggregate’s +0.6% total return, edging out high-yield’s +0.5% gain.
International stocks were mixed. Developed Markets gained +0.6%, modestly outperforming the S&P 500, while Emerging Markets fell -2.4%. Year-to-date, both regions are outperforming the S&P 500 by more than +10%.

The Market's Tug-of-War with the Federal Reserve

The stock market was volatile in November as the Federal Reserve managed investor expectations for a December rate cut. The volatility started after the Fed’s late-October meeting, when Chair Powell said a December rate cut was “not a foregone conclusion”. Market-implied odds for a third consecutive rate cut fell from 98% in late October to around 40% in mid-November, as multiple Fed officials questioned the need for another rate cut. The uncertainty weighed on the stock market, with the S&P 500 trading lower and eventually bottoming on November 20th. Sentiment then shifted again late in the month as comments from influential Fed members, rising unemployment, and favorable inflation data pushed the odds of a December cut back above 80%.

The market’s reaction wasn’t just about a -0.25% rate cut, but rather what the Fed’s decision signaled about the future. A December cut would affirm the bullish narrative that the Fed was pulling off a “soft landing”, whereby the central bank proactively lowers interest rates to reduce the risk of recession. When the odds of a December cut initially fell, the market sold off as investors reassessed that optimistic outlook. Leaving rates unchanged would keep financial conditions tighter for longer, potentially slowing the economy and earnings growth. The late month rebound, fueled by rising expectations of a December cut, reflected increased clarity and confidence about the path ahead.

The AI Trade Moves to the Next Phase as Investors Become More Selective

Artificial intelligence remains a key market driver with 7 of the 10 largest S&P 500 companies, or nearly 30% of the index, tied to the AI industry. In November, there was a noticeable shift in investor sentiment toward AI stocks, moving from broad enthusiasm to increased scrutiny and selectivity. The month began with concerns over the expensive valuations of the Magnificent 7 tech giants, particularly those most reliant on the AI infrastructure buildout. Questions emerged about whether the massive capital spending on data centers and cloud infrastructure will translate into profits strong enough to justify the companies’ high valuations. This skepticism around AI’s economics led to a sell-off across the AI industry, with companies like Nvidia and Amazon down over -10% at times. Given the S&P 500’s extreme concentration in mega-cap technology stocks, the focused weakness was a major factor dragging down the index. Figures 1-5-Dec-03-2025-08-31-17-6417-PM
