US stocks kicked off September trading on a down note, with major indices posting moderate declines in a holiday-shortened week following Labor Day. The sell-off was broad-based but particularly pronounced in tech-heavy sectors, as investors grappled with a fresh court ruling on tariffs that introduced significant uncertainty. Based on the provided data and market reports, here’s a summary of the key index performances:
Market Indices

- S&P 500: Closed at 6,415.54, down -44.72 (-0.69%). The index faced pressure from tech and consumer discretionary sectors, retreating from its recent 52-week high of 6,460.26. Trading volume spiked to 97.36 million shares, reflecting heightened investor activity during the downturn.
- Dow Jones Industrial Average: Closed at 45,295.81, down -249.07 (-0.55%). The index experienced a modest decline, with financial and industrial sectors providing resilience, remaining near the upper end of its 52-week range (45,544.88). Volatility stayed moderate.
- Nasdaq Composite: Closed at 21,279.63, down -175.92 (-0.82%). Tech stocks, especially in AI and semiconductors, drove the decline, with profit-taking following Nvidia’s recent earnings strength. The index remained within its 52-week range (21,455.55) but hinted at a correction.
- Russell 2000 Index: Closed at 2,352.21, down -14.21 (-0.60%). Small-caps pulled back from their 52-week high of 2,366.42, affected by inflation fears and waning rate cut optimism. Moderate volatility underscored market uncertainty.
- VIX (Volatility Index): Closed at 15.25, up +0.75 (+5.17%). The rise signaled increased market uncertainty, likely due to economic data and geopolitical tensions, reversing the recent stability trend from 15.36 on August 29.
Political Factors
- Trump’s Tariff Policy Signals: The Trump administration hinted at revisiting the 90-day tariff pause on China, reigniting trade war fears that pressured manufacturing and export-related stocks, contributing to the day’s losses.
- Fed Policy Uncertainty: Speculation about Scott Bessent’s potential nomination as Fed Chair intensified, raising concerns about policy shifts under new leadership, despite Jerome Powell’s earlier assurances, adding to market jitters.
Diplomatic Factors
- Ukraine Peace Talks Stalemate: Stalled negotiations between Ukraine and Russia heightened geopolitical risks, boosting volatility in energy and defense stocks.
- Middle East Tensions: A minor escalation in Middle East conflicts drove oil price concerns, impacting global markets and adding pressure on energy-dependent equities.
Social Factors
- Labor Day Aftermath: Post-Labor Day (September 1) consumer spending data indicated a slowdown, dampening retail sector optimism and affecting stocks like Walmart and Target.
- Consumer Confidence Dip: A slight decline in consumer confidence due to inflation worries reduced discretionary spending sentiment, influencing market dynamics.
Economic Factors
- Inflation Data Concerns: Revised CPI and PCE data pointed to higher-than-expected inflation, casting doubt on the Fed’s September rate cut timeline and pressuring growth stocks.
- Jobless Claims Rise: Initial jobless claims rose to 245,000, signaling a softening labor market, which fueled recession fears and contributed to the sell-off.
- Commodity Price Surge: Rising oil and metal prices intensified inflation pressures, encouraging a shift toward defensive stocks and away from cyclical sectors.
Stock Price and Corporate Factors
- Nvidia Post-Earnings Pullback: Nvidia’s stock dipped after its strong Q2 earnings as investors locked in profits, dragging the Nasdaq lower.
- Tesla Supply Chain Issues: Tesla faced setbacks from supply chain disruptions, causing a decline despite earlier production expansion news.
- Intel Competitive Pressure: Intel’s stock weakened amid ongoing semiconductor competition concerns, despite a boost from SoftBank investment.
- Palantir Profit-Taking: Palantir saw profit-taking after recent gains from AI contract wins, adding to Nasdaq’s broader decline.
Global Market Influence
- Americas Region: The S&P/TSX (Canada) fell -0.40%, and IBOVESPA (Brazil) dropped -0.75%, aligning with U.S. trends amid commodity price volatility.
- Asia and Europe: Asian markets (e.g., Nikkei 225 -1.20%, Hang Seng -1.50%) and European indices (e.g., FTSE 100 -0.80%, CAC 40 -1.90%) saw steeper declines, reflecting a global risk-off sentiment.
Outlook
Today’s market (September 3, 07:28 AM KST) will likely focus on further Fed commentary and the upcoming ISM manufacturing data. The current downward trend may persist due to inflation and geopolitical risks, though tech and small-cap resilience could cap losses. Investors should also watch for global holiday impacts, including Chuseok in Korea (mid-September), which may affect liquidity.
