Stock market today: Dow slides 500 points, S&P 500 notches 4th day of losses as Nvidia earnings loom

U.S. equities slid as risk‑off sentiment around an apparent AI bubble and macro uncertainty hit markets: the Dow fell about 1.1% (nearly 500 points), the Nasdaq dropped roughly 1.2% and the S&P 500 clocked a fourth consecutive loss of about 0.8%; Bitcoin briefly dipped below $90,000, erasing its year‑to‑date gains. Investors are focused on two near‑term tests — Nvidia’s Q3 results on Wednesday (NVDA shares were down ~2.7% in the session, with Amazon and Microsoft off ~4.3% and ~2.7%) and the delayed September jobs report on Thursday — which will recalibrate expectations for Fed policy after traders pared rate‑cut odds to roughly 50/50; ADP data showed private‑sector job losses slowing. Retail earnings, highlighted by Home Depot’s earnings miss and full‑year profit guidance cut, will further inform views on consumer resilience into the holiday season, making this week pivotal for positioning and macro policy outlooks.

Analysis

U.S. equities moved decisively lower on Tuesday with the Dow Jones Industrial Average down about 1.1% (nearly 500 points), the Nasdaq Composite off roughly 1.2%, and the S&P 500 falling about 0.8% to record a fourth straight daily loss. Bitcoin briefly dipped below $90,000 for the first time in seven months, erasing year-to-date gains and reinforcing the session's risk-off tone.

Market participants cited concerns about an AI-driven valuation bubble as Nvidia (NVDA) prepares to report Q3 results on Wednesday; NVDA shares fell roughly 2.7 in the session while peers Amazon and Microsoft declined roughly 4.3% and 2.7%, respectively, amplifying downside in mega-cap tech. The timing of Nvidia’s print and concentrated exposure to AI narratives make near-term volatility likely for high-multiple names.

Macro catalysts compound the uncertainty: Thursday’s delayed September jobs report will inform Federal Reserve policy expectations after traders pared rate-cut odds to about 50/50, while ADP data showed private-sector job losses slowing. Retail earnings are a secondary risk vector after Home Depot missed estimates and cut full-year profit guidance, with Walmart and Target results this week set to refine views on consumer health ahead of the holidays.

Key Decisions for Investors

• Reduce near-term exposure to AI-concentrated and high-momentum tech names (including NVDA, AMZN, MSFT) and size positions conservatively ahead of Nvidia Q3 results and the delayed September jobs report; consider short-dated option protection to hedge downside risk
• Avoid initiating new cyclical consumer positions until Walmart and Target earnings clarify demand trends, and consider trimming existing retail exposure after Home Depot's earnings miss and full-year profit guidance cut
• Increase liquidity or defensive allocation and monitor the jobs report, ADP trends, and Fed guidance closely — with market-implied rate-cut odds near 50/50 and crypto volatility (Bitcoin < $90k) as potential triggers for broader risk-off flows
