U.S. stocks rebounded on semiconductor shares Tuesday, but gains were concentrated in tech heavyweights, with AI compute growth, trading regulation and energy costs still reshaping market expectations, and midterm election results not yet settled.
1 | Nasdaq rises 0.8%, Dow falls 0.4%, semiconductor stocks halt decline and rebound
U.S. stocks closed mixed on Tuesday, midterm Election Day: the S&P 500 rose 0.36% to 7,568.92, the Nasdaq rose 0.83% to 25,372.01, and the Dow fell 0.38% to 51,786.72. Reuters said Nvidia rebounded about 3% and the Philadelphia Semiconductor Index rose about 3%, ending several consecutive days of declines. Apple fell about 2.2% on rising memory costs and pressure on holiday-quarter gross margins. The Associated Press noted that most S&P 500 constituents declined, with the index gain supported more by a handful of heavyweight tech stocks. Reading the Nasdaq rebound as a recovery in risk appetite across the whole market is still premature; what follows will depend on election results, interest rates and whether chip stocks can lift broader sectors.

2 | AMD data center revenue up 97% year over year, fourth-quarter revenue guidance raised to $17 billion
Advanced Micro Devices reported third-quarter revenue of $13.4 billion, up 45% year over year, with data center business revenue of $8.5 billion, up 97% year over year, both quarterly records. The company expects fourth-quarter revenue of about $17 billion, plus or minus 3%, with the midpoint implying 66% year-over-year growth, above analyst expectations compiled by Reuters. The company attributed growth to stronger demand for Instinct accelerators and EPYC server processors, and said capacity is expanding for its next-generation Helios and Venice products. Data center revenue nearly doubling shows that AI infrastructure spending is also pulling server processors, not just GPUs. The $17 billion figure is still a company forecast, and whether it is met depends on supply expansion and the pace of customer deployments.

3 | CFTC says U.S. equity perpetual contracts can begin trading, coalition backed by traditional financial institutions sues the same day
Commodity Futures Trading Commission Chairman Mike Selig said single-stock perpetual contracts can begin trading on certain dual-registered exchanges. These exchanges must be registered with the CFTC and register securities futures products with the U.S. Securities and Exchange Commission. On the day of the announcement, the Capital Markets Coalition, backed by institutions including Citadel Securities and Cboe, sued the CFTC in the federal court for the Southern District of New York, arguing that such contracts should fall under the securities regulatory framework and challenging the commission's approval path. Perpetual contracts have no expiration date and were previously mainly seen in crypto markets. A policy statement does not mean the dispute is over; the lawsuit could determine whether U.S. equity derivatives can adopt a similar structure.

4 | Apple Opens Siri AI Access to Developers, Third-Party Apps Can Invoke Cross-App Actions
Apple has opened a Siri AI developer preview in iOS 27.3 and other system betas, allowing apps to connect content and actions to Siri through App Intents, and developers can also use "skills" to chain multiple actions into a single experience. Users can invoke app functions using natural language, and the system can also execute tasks by combining personal context and on-screen content. Third-party apps remain in preview stage, with App Store submissions expected to open in spring 2027. Apple is extending the AI competition from its own assistant to the developer ecosystem, though actual results will still depend on app integration and experience stability. Currently supported languages include English, French, Japanese, Korean, Portuguese, and Spanish; the EU is not yet available, and Traditional Chinese is listed as a later supported language.

5 | Von der Leyen Says Hormuz Blockade Has Cost EU an Extra €127 Billion in Energy Spending
European Commission President Ursula von der Leyen said at the Brussels summit that since the closure of the Strait of Hormuz, Europe has paid an extra €127 billion for fossil fuels it was already purchasing, without obtaining additional energy. She used this to illustrate the costs of Europe's energy dependence and called for advancing clean energy and industrial transformation. This figure is a cumulative estimate given by von der Leyen in her speech, not a new fiscal allocation announced at the summit. It also means that energy import risks are not just a bookkeeping burden but will ultimately translate into corporate energy costs and pressure on industrial competitiveness. For the market, the focus is not only on oil and gas prices but also on supply rerouting, industrial costs, and European competitiveness; the bill for a prolonged blockade is turning into pressure on industrial policy.
