The U.S. stock market concluded Friday, October 31, 2025, on a strong note, capping off a remarkably positive week and month for major indexes, largely propelled by robust earnings from tech giants like Amazon (AMZN<\/a>). Investor sentiment remained elevated as strong corporate results and a surprising trade truce between the U.S. and China provided significant tailwinds.<\/p>\n

Day's Performance Recap: Amazon Leads the Charge<\/h2>\n

On Friday, the S&P 500<\/a> Index rose 0.3%, closing at 6,840.20 and moving closer to its all-time high set earlier in the week. The Dow Jones<\/a> Industrial Average added 0.1%, reaching 47,562.87, while the technology-heavy Nasdaq Composite surged 0.6% to 23,724.96. This performance marked the S&P 500's third consecutive winning week and its sixth straight winning month, a streak not seen since 2021. Similarly, the Nasdaq, Dow, and S&P 500 all posted solid weekly and monthly gains, with the Nasdaq climbing 2.2% for the week and 4.7% for October, and the S&P 500 and Dow advancing 0.7% and 0.8% for the week, respectively. For the month of October, the S&P 500 gained 2.3% and the Dow advanced 2.5%.<\/p>\n

The primary catalyst for Friday's market upswing was Amazon (AMZN<\/a>), whose shares jumped 9.6% to an all-time high after the retail and cloud computing giant reported significantly stronger-than-expected quarterly profits. Amazon's massive market capitalization, now approximately US$2.4 trillion, means its stock movements exert considerable influence on the S&P 500, to the extent that the index would have been down for the day without its stellar performance. CEO Andy Jassy highlighted an acceleration in the growth of Amazon's booming cloud-computing business, Amazon Web Services (AWS), a pace not observed since 2022.<\/p>\n

After-Hours Earnings Impact from Thursday<\/h2>\n

The positive momentum from Amazon's earnings helped to offset lingering concerns from earlier in the week. After the market close on Thursday, October 30, 2025, both Amazon and Apple (AAPL<\/a>) released their quarterly results. While Apple's shares finished the regular session up 0.6%, both stocks saw jumps in after-hours trading in response to robust reports. Apple, the world's second-most-valuable company with a market capitalization exceeding $4 trillion, also posted strong results.<\/p>\n

This contrasted with the market's reaction to earnings reports from fellow "Magnificent Seven" members Meta Platforms (META<\/a>) and Microsoft (MSFT<\/a>), which had reported after the close on Wednesday. Shares of Meta sank 11% and Microsoft fell 3% on Thursday, dragging down the major indexes. Meta's significant drop was attributed to investor concerns over ballooning AI-related expenses and an increased capital expenditure forecast for 2025. However, the strong performance from Amazon and Apple helped to reverse Thursday's selling pressure, underscoring the market's selective enthusiasm for AI-driven growth.<\/p>\n
