Sinking Nvidia keeps Wall Street’s gains in check

The U.S. stock market experienced modest gains, with the S&P 500 up 0.2%, as Nvidia's 2.4% decline—triggered by SoftBank's $5.83 billion stake sale—weighed heavily on the index, offsetting broader market strength. While some AI-related stocks like BigBear.ai surged, CoreWeave fell despite strong earnings due to supply chain issues, indicating mixed sentiment within the sector. Concurrently, a softening job market is increasing expectations for a December Fed rate cut, despite persistent inflation and economic data uncertainty stemming from a potential government shutdown, which complicates the monetary policy outlook.

Analysis

The S&P 500 saw a modest 0.2% gain, significantly constrained by Nvidia's (NVDA) 2.4% decline, which, given its near-$5 trillion valuation, was the heaviest index weight. This drop followed SoftBank's $5.83 billion stake sale, despite SoftBank's ongoing AI focus on OpenAI. The broader market exhibited mixed performance, with the Nasdaq down 0.2% and the Dow up 1%, underscoring mega-cap tech's outsized influence.
The AI sector demonstrated divergent performance: BigBear.ai (BBAI) jumped 10.9% on strong results and a $250 million acquisition of AskSage. Conversely, CoreWeave fell 14.8% despite exceeding revenue and loss forecasts, as investors focused on supply-chain issues delaying a data center and deferring future revenue. This highlights a nuanced investor perspective, prioritizing operational clarity alongside growth.

Macroeconomic factors are shaping investor expectations, with a softening job market, including an estimated 50,000 job cut in October, increasing the likelihood of a December Fed rate cut to two-in-three. This outlook persists despite inflation remaining above the Fed's 2% target and economic data uncertainty from a potential government shutdown. The Fed's policy path remains complex amid these conflicting signals.

Key Decisions for Investors

• Monitor Nvidia's price action and its disproportionate impact on broader index funds, given its significant market capitalization and recent volatility.
• Evaluate AI sector investments for operational execution and supply chain risks, as demonstrated by CoreWeave's reaction, rather than solely focusing on growth metrics.
• Factor in the increasing probability of a December Fed rate cut, while closely watching inflation data and government shutdown developments for potential shifts in monetary policy.
