# Wall Street Tech Rebound Faces Global Market Uncertainty and Election Jitters US tech stocks surge despite Apple's decline, while global markets navigate interest rate pressures. - **Source:** [Sydney Morning Herald - Business](https://www.smh.com.au/rss/business.xml) - **Published:** 2026-11-03 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/98816dfc-9efd-4e4f-917c-d4a750d336c1 ## Tech Sector Market Divergence Wall Street experienced a split performance as influential Big Tech stocks rebounded, driving the S&P 500 up 0.5 percent despite broader index declines. The Nasdaq composite climbed 1 percent, while the Dow Jones Industrial Average dropped 0.5 percent. This volatility highlights ongoing investor anxiety regarding artificial intelligence valuations and sustainability. ## Semiconductor Gains Fuel Growth Nvidia led the market upward with a 3.2 percent gain, supported by significant rises in Broadcom at 3.2 percent, Advanced Micro Devices at 5.5 percent, and Micron Technology at 2.6 percent. These chipmakers remain central to the AI boom, contrasting sharply with the broader market's mixed trading and recent instability. ## Apple Faces AI Cost Pressures Apple shares fell 2 percent as the company warned of lower profit margins for the final quarter. Increased demand for AI data centers has inflated memory chip costs, impacting Apple despite reporting quarterly revenue and profit that exceeded expectations. This demonstrates how AI infrastructure spending creates complex ripple effects across tech. ## Palantir Commercial Revenue Surge Palantir Technologies shares declined 2.1 percent despite beating profit forecasts. The company noted a significant shift in its business model, with US commercial revenue soaring 148 percent from the previous year. For the first time, Palantir generated more income from private US companies than from government contracts during this period. ## Election Uncertainty and Policy Midterm elections are contributing to market instability, though historical data since 1970 shows the S&P 500 typically yields positive returns in the six months following such events. Investors speculate that a Democratic sweep could increase AI regulation, yet many prefer split control of Washington to avoid transformative economic policy shifts. ## Global Markets and Interest Rates The Australian sharemarket is expected to retreat by 0.3 percent following a 0.3 percent gain on Tuesday. This occurred as the Reserve Bank of Australia raised interest rates to an 18-year high. Meanwhile, South Korea’s Kospi index dropped 3.6 percent, heavily impacted by losses within its major semiconductor manufacturing sector. ## Economic Indicators and Yields US job market reports indicated more openings in September than economists anticipated, signaling continued economic resilience. Consequently, the yield on the 10-year Treasury rose to 4.96 percent from 4.91 percent. Oil prices also remained volatile, with Brent crude fluctuating amid ongoing uncertainty regarding the conflict involving Iran and global supply. ## Future Market Outlook Investors remain focused on whether corporate profits can sustain growth amid high inflation and elevated interest rates. While companies like Revvity and DuPont exceeded expectations, the market's reliance on AI-driven tech stocks creates a fragile environment. Future performance depends on balancing these sector-specific gains against broader macroeconomic and political risks. ## Sources covering this story - [Sydney Morning Herald - Business — ASX Set to Retreat as Tech Stocks Drive Wall Street Rebound](https://www.smh.com.au/business/markets/asx-set-to-slide-tech-stocks-boost-wall-street-20261104-p61b54.html?ref=rss&utm_medium=rss&utm_source=rss_business) - [NYT > Business — Stock Market Volatility Amid Midterm Election Uncertainty](https://www.nytimes.com/2026/11/04/business/midterm-elections-stock-market.html) --- _Summary written by Brifing from the original reporting.
