The S&P 500 rose by 44.60 points, or 0.58%, closing at 7757.17, while the Dow Jones increased by 360.21 points, or 0.69%, finishing at 52856.09. The Nasdaq surged by 278.04 points, or 1.05%, to close at 26702.86. In earnings news, Tesla reported third-quarter earnings that exceeded Wall Street estimates, showcasing resilience despite a decline in auto revenue. The company’s strong performance has bolstered investor confidence, contributing to the overall market rally. Meta also posted impressive third-quarter results, beating revenue expectations and providing strong guidance for future growth. This positive news has helped lift the tech sector, with Meta's stock reacting favorably to the earnings announcement. On the macroeconomic front, discussions around monetary policy continue to influence market sentiment. Investors are weighing the implications of interest rates on mortgage payments, as some homeowners debate whether to pay off their mortgages early. In corporate news, Elon Musk announced that SpaceX and Tesla are exploring a potential merger, which could consolidate his holdings in rockets, cars, and artificial intelligence into a single entity valued at over $3 trillion. However, some analysts express skepticism about the feasibility and potential benefits of such a merger. Additionally, Meta has been ordered to pay $25 billion to New Mexico for deceiving users about privacy on Facebook, which could have implications for the company's reputation and future earnings. Looking ahead, the market remains optimistic as earnings season continues, with investors eager to see how other companies perform in the coming weeks. The focus will likely remain on tech stocks and any developments regarding the potential Tesla-SpaceX merger. ### EXPLORE MORE POSTS [![US Market Summary for October 21, 2026](https://resources.quantel.ai/hubfs/Partners%20images/iStock-2260783305.jpg)](https://resources.quantel.ai/daily-market-summary/us-market-summary-october-21-2026) #### US Market Summary for October 21, 2026 The US stock market closed higher on October 21, 2026, with the Nasdaq...
