Dow Jones Today: Stock Indexes Little Changed on 2nd Day of Government Shutdown; S&P 500, Nasdaq Hit New Record Highs

Major stock indexes were largely flat Thursday after earlier highs, as the second day of the U.S. government shutdown delayed key economic data, complicating Federal Reserve interest rate decisions. Sector-specific movements were prominent: chip shares rallied globally following OpenAI's partnership with SK Hynix and Samsung for its Stargate AI project, while Fair Isaac (FICO) surged 20% after announcing new models that bypass credit bureaus, causing TransUnion and Equifax to tumble. Additionally, Occidental Petroleum fell 7% as Berkshire Hathaway acquired its OxyChem unit for $9.7 billion, marking Berkshire's largest acquisition since 2022, and OpenAI's valuation reportedly reached $500 billion.

Analysis

The market is exhibiting a classic divergence between muted macroeconomic sentiment and high conviction on specific corporate catalysts. While major indices remain range-bound due to the U.S. government shutdown delaying key economic data and complicating the Federal Reserve's upcoming interest rate decision, specific sectors and stocks are experiencing significant price action. The artificial intelligence theme remains a powerful driver, with OpenAI's partnership with SK Hynix and Samsung for its Stargate project triggering a global rally in chipmakers, including AMD (+4%) and Nvidia (+1%). In a major market disruption, Fair Isaac (FICO) shares surged 20% on its announcement of a new direct-to-lender model, which in turn caused shares of credit bureaus TransUnion (TRU) and Equifax (EFX) to plummet 10% and 8% respectively. M&A activity was also a key focus, with Berkshire Hathaway's $9.7 billion all-cash acquisition of Occidental Petroleum's (OXY) chemical division leading to a 7% drop in OXY's stock, suggesting a 'sell the news' reaction to the divestiture. In contrast, Tesla (TSLA) shares fell 3% despite beating third-quarter delivery estimates (497,000 vs. 440,000 forecast), indicating that after a 40% Q3 rally, the stock's valuation is more sensitive to its long-term growth narratives like robotaxis than to immediate operational performance.

Key Decisions for Investors

• Investors should immediately reassess long-term positions in credit bureaus like Equifax (EFX) and TransUnion (TRU), as Fair Isaac's (FICO) new direct-to-lender model poses a significant structural threat to their role as intermediaries.
• Maintain exposure to the semiconductor sector, which continues to benefit from the AI infrastructure build-out, but be mindful of near-term profit-taking in stocks like Intel (INTC) that are showing overbought technical signals.
• Recognize that Tesla's (TSLA) valuation is increasingly decoupled from near-term delivery figures and is instead driven by future growth catalysts, implying that positive operational news may not prevent profit-taking after significant share price appreciation.
• Exercise caution with broad market index positions given that the government shutdown is withholding crucial economic data, creating significant uncertainty for the Federal Reserve's next policy move and potentially increasing market volatility.
