CNBC Daily Open: The U.S. government shuts down after stocks end September buzzing

The U.S. government has shut down, potentially delaying September's jobs report and leaving the Federal Reserve and investors without critical labor market data. Despite this, markets largely shrugged off concerns, with the Dow Jones Industrial Average hitting a new high and the S&P 500 gaining over 3% in September, driven by a surge in AI-related deals, including record closes for Nvidia. Separately, Berkshire Hathaway is reportedly pursuing a $10 billion acquisition of OxyChem, and the Reserve Bank of India maintained its interest rates at 5.5% as anticipated.

Analysis

The U.S. financial markets are exhibiting a significant disconnect from emerging macroeconomic and political risks. Despite a U.S. government shutdown that will delay the release of September's jobs report, creating uncertainty for Federal Reserve policy, the Dow Jones Industrial Average reached a new high. This market resilience appears largely attributable to sector-specific momentum, particularly in artificial intelligence, which propelled the S&P 500 to a 3% gain in September, strongly outperforming its historical average of a 4.2% decline. Key catalysts include Nvidia (NVDA) achieving a record high and CoreWeave (CRWV) jumping nearly 12% on an AI infrastructure deal with Meta. In parallel, the M&A landscape remains active, evidenced by Berkshire Hathaway's reported pursuit of a $10 billion deal for Occidental Petroleum's (OXY) petrochemicals unit. This bullish sentiment, however, contrasts with a mixed global picture, including weakening business sentiment in Japan and persistent geopolitical concerns surrounding Russia's threat to European security.

Key Decisions for Investors

• Investors should monitor for heightened volatility around Fed policy expectations, as the government shutdown's delay of the September jobs report has removed a critical data point for upcoming monetary decisions.
• Given the market's strong performance is narrowly driven by the AI theme, it is prudent to assess concentration risk in technology portfolios and acknowledge the divergence from broader macroeconomic uncertainties.
• Closely watch developments related to Occidental Petroleum (OXY), as the reported $10 billion acquisition interest from Berkshire Hathaway for its OxyChem unit represents a potential valuation catalyst.
