S&P 500 Hits Record High as AI Momentum and Bond Calm Offset Inflation Fears
The S&P 500 closed at a record high of 7,820.85 on Tuesday, its first all-time peak since mid-August, driven by AI enthusiasm and easing bond volatility. The Nasdaq and Dow also hit records, while oil prices rose slightly due to geopolitical tensions. Analysts note the rally is narrow, heavily reliant on mega-cap tech, while broader market segments have suffered significant drawdowns.
Key points
- The S&P 500 rose 0.6% to 7,820.85, the Nasdaq added 0.5% to 27,599.79, and the Dow gained 0.5% to 51,521.22, all closing at record highs.
- The rally was fueled by a rebound in the AI trade, muted oil prices, and a pause in the steep sell-off of U.S. Treasuries, with the 10-year yield falling to 5.276%.
- A softer September jobs report reduced expectations for immediate Federal Reserve rate hikes, supporting equity markets despite high bond yields.
- Brent crude rose 0.5% to $101.13 per barrel due to attacks on ships in the Strait of Hormuz and supply concerns in Yemen, despite G7 emergency reserve releases.
- Skydance closed 2.7% lower after completing its $110 billion acquisition of Warner Bros. Discovery, while Constellation Energy surged 12% following a 20-year power deal with Google.
Background
This record close follows a muted September and marks the fourth year of a bull market that began in 2022. Earlier in October, the S&P 500 had already gained every trading day, recovering from a historic sell-off in U.S. Treasuries. The current rally contrasts with a broader market weakness, where cyclically oriented stocks have faced sharp corrections, creating a divergence between mega-cap tech performance and the average stock's drawdown.
Why it matters
The record high underscores the dominance of AI-driven mega-caps in supporting broad market indices, even as underlying economic stress and high bond yields pose risks to other sectors. The narrowness of the rally, with the average S&P 500 member experiencing a 14% maximum drawdown since August, highlights potential fragility. Upcoming earnings from major banks and continued bond volatility will be critical in determining whether this record close signals a sustainable trend or a temporary relief rally.
What to watch
Investors will focus on the start of the U.S. quarterly earnings season next week, beginning with major banks like JPMorgan and Bank of America. Market sentiment will also depend on whether bond and oil volatility continues to compress, as well as any diplomatic developments between the U.S. and Iran that could affect oil supply and prices.
