The S&P 500 fell by 4.4%, marking its worst daily decline since April 2025, while the tech-heavy Nasdaq entered correction territory. The sell-off was particularly brutal for AI stocks, leading to a staggering loss of approximately $2.9 trillion in market capitalization across the S&P 500. #### Earnings Magnolia Oil & Gas reported positive developments in its Q3 2026 earnings call, noting that wildfire integration is progressing faster than anticipated and that it has met its debt targets ahead of schedule. Meanwhile, NorthWestern Energy faced challenges in its Q3 2026 earnings, citing Colstrip losses and mild weather as factors that pressured its margins. #### Macroeconomics As inflation continues to impact the economy, the 2027 tax brackets have been released, indicating a steeper adjustment compared to this year. This change highlights the ongoing presence of inflation in the economic landscape. Additionally, the October jobs report is set to be released on Friday, which could either provide relief to investors or exacerbate current market concerns following the tech-stock rout. #### Corporate News In notable corporate news, the New York Times Company is in advanced talks to acquire Letterboxd for approximately $330 million. This acquisition is part of the company's strategy to expand its portfolio with new products and services. #### Outlook Looking ahead, the market remains on edge as investors await the upcoming jobs report, which could significantly influence market sentiment. The recent tech-stock sell-off raises questions about the durability of the AI build-out and its implications for future market performance. With the Nasdaq now in correction territory, historical trends suggest a potential for recovery, but uncertainty looms large. ### EXPLORE MORE POSTS [![US Market Summary for November 5, 2026](https://resources.quantel.ai/hubfs/Partners%20images/iStock-2260783305.jpg)](https://resources.quantel.ai/daily-market-summary/us-market-summary-november-5-2026) #### US Market Summary for November 5, 2026 #### Market Overview Today, the US stock market experienced a significant...
