Stock market today: Dow eyes record on UnitedHealth surge, S&P 500, Nasdaq fall as rate-cut bets cool

US equities presented a mixed picture, with the Dow nearing a record high, buoyed by UnitedHealth's surge following a Berkshire Hathaway stake disclosure. Meanwhile, the S&P 500 and Nasdaq declined as cooling rate-cut expectations, driven by hotter-than-expected wholesale inflation and solid retail sales, combined with President Trump's announced semiconductor tariffs. This broader market sentiment was further influenced by deteriorating consumer sentiment and notable sector-specific movements, including Intel's gain on potential government investment and Applied Materials' 14% drop due to weak China demand and tariff concerns.

Analysis

US equity markets exhibited significant divergence, with the Dow Jones Industrial Average (^DJI) approaching a record high while the S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) fell 0.3% and 0.4% respectively. This split performance was driven by a recalibration of interest rate expectations following stronger-than-expected economic data, including a hot Producer Price Index and a solid 0.5% rise in July retail sales, which tempered bets for an aggressive Federal Reserve rate cut. Compounding the negative sentiment, particularly for the tech sector, was President Trump's announcement of forthcoming tariffs on semiconductor imports. The impact of this policy risk was starkly illustrated by Applied Materials (AMAT) stock plummeting 14% after issuing a weak fourth-quarter forecast citing sluggish demand in China. Conversely, company-specific catalysts provided powerful upside, with major Dow component UnitedHealth (UNH) soaring after a filing revealed Berkshire Hathaway acquired a 5 million share stake, and Intel (INTC) shares jumping on reports of a potential US government investment, showcasing a market highly sensitive to both macroeconomic headwinds and idiosyncratic news flow.

Key Decisions for Investors

• Investors should re-evaluate exposure to rate-sensitive assets, as recent inflation and retail sales data are reducing the probability of significant near-term Fed rate cuts.
• Exercise extreme caution within the semiconductor sector due to heightened tariff risks, highlighted by Applied Materials' (AMAT) 14% decline, while monitoring for companies like Intel (INTC) that could receive specific government support.
• In this divergent market, consider focusing on fundamentally strong companies with unique positive catalysts, such as UnitedHealth's (UNH) outperformance following the Berkshire Hathaway investment, which may offer insulation from broader macroeconomic volatility.
