- The S&P 500 closed Tuesday at 7,568.92 points, up 0.36 percent.
- U.S. stock futures were modestly higher before Wednesday's session after Democrats won control of both chambers of Congress.
- Investors are weighing possible restrictions on data-center construction alongside a rebound in major technology and semiconductor stocks.
The S&P 500 is heading into Wednesday's U.S. trading session after closing Tuesday at 7,568.92 points, a gain of 27.52 points or 0.36 percent. The benchmark's previous session was supported by a rebound in influential technology and semiconductor shares, while investors followed the U.S. midterm elections.
Futures edge higher before the open
U.S. stock futures were modestly higher before the opening bell after Democrats won control of both the House of Representatives and the Senate. Yahoo Finance reported that S&P 500 futures were up 0.2 percent in its Wednesday morning update. The political result is being assessed for its possible implications for tariffs, healthcare policy and regulation of artificial-intelligence infrastructure.
Technology remains the key swing factor
The prior session showed how strongly large technology companies can influence the broad index. According to CommBank, citing AAP, Nvidia rose 2.3 percent and Broadcom gained 3.1 percent, while Microsoft, Amazon and Meta Platforms each advanced by more than 2 percent. Those gains helped the S&P 500 rise even though most index constituents declined. Apple fell 1.9 percent after warning that higher memory-chip costs could pressure its holiday-quarter margins.
The contrast leaves the index sensitive to renewed debate about the returns on extensive AI investment. At the same time, the election outcome has increased attention on potential limits for new data-center construction, particularly as investors assess the effect on chip demand and technology-company capital spending.
Economic data and earnings ahead
Wednesday's calendar includes the final U.S. services and composite purchasing managers' readings, the ISM services survey and private payrolls data. Investors are also scheduled to receive results from companies including Arm Holdings, Qualcomm, McDonald's, Novo Nordisk and Uber. These releases may provide additional signals on consumer demand, labor-market conditions and the continuing strength of AI-related spending.
For now, the S&P 500's Tuesday close provides the latest completed-session reference point; the next official index reading will come after the U.S. market opens. Further S&P 500 coverage is available on the S&P 500 topic page.
