Wall Street finished the latest session with a mixed performance as investors rotated back into large-cap artificial intelligence stocks while selling down financials and housing-related equities after President Donald Trump said his administration would move to ban corporate purchases of single-family homes. The announcement injected fresh political risk into US property markets while reinforcing the growing divergence between technology-led growth stocks and the rest of the economy.

The S&P 500 closed lower despite hitting an intraday record earlier in the session, dragged down by declines in banks and private equity-linked stocks. In contrast, the Nasdaq Composite edged higher as heavyweight technology names such as Nvidia, Microsoft and Alphabet attracted renewed buying on optimism surrounding artificial intelligence investment and earnings growth.
The market reaction reflects two competing forces shaping US equities in early 2026: political intervention in housing and corporate ownership on one side, and continued capital inflows into high-growth AI and technology platforms on the other.
Key Market Moves and Index Performance
US equity markets closed mixed as investors digested economic data, political developments and sector-specific catalysts.
Key index moves included:
- S&P 500: down 23.64 points (–0.34%) to 6,921.18
- Nasdaq Composite: up 39.30 points (+0.17%) to 23,586.47
- Dow Jones Industrial Average: down 472.60 points (–0.96%) to 48,999.39
The S&P 500 ended lower after setting a fresh intraday record, highlighting growing sensitivity to profit-taking and sector rotation. Financial stocks, including JPMorgan and Blackstone, were among the heaviest drags, while technology and AI-linked names provided support for the Nasdaq.
Compared with long-term market averages, the Nasdaq’s resilience underscores how capital is increasingly concentrated in a narrow group of mega-cap technology stocks, a pattern reminiscent of previous technology-led cycles.
Trump Targets Corporate Home Buying
The day’s most disruptive policy signal came from President Trump, who said the US government was moving to ban Wall Street firms from buying single-family homes as part of a broader effort to reduce housing costs and restore affordability for American households.

In a social media statement, Trump said his administration would take immediate steps to implement the ban and would seek to have Congress codify it into law. The policy aims to curb institutional investors that have acquired large portfolios of rental homes since the 2008 financial crisis.
“People live in homes, not corporations,” Trump said, adding that inflation and rising property prices had put the American dream out of reach for many families ahead of this year’s congressional midterm elections.
The announcement triggered an immediate sell-off in property and private equity-linked stocks. American Homes 4 Rent, one of the largest single-family rental operators, fell sharply, while Blackstone, a major institutional owner of rental housing, also declined.
Homebuilders and housing-related shares followed lower, reflecting concerns that reduced institutional participation could weaken demand, disrupt construction pipelines, and introduce regulatory uncertainty into the sector.
How Big Is Wall Street’s Role in Housing?
Institutional ownership of US housing remains relatively small in absolute terms, but it is politically sensitive. Government and academic research suggest large investors control roughly 2–4 per cent of the single-family rental market, with higher concentrations in certain urban and Sun Belt regions.
Since the global financial crisis, private equity firms and specialist landlords have bought hundreds of thousands of foreclosed or newly built homes, creating scale-driven rental portfolios that compete with individual buyers.
Supporters of Trump’s proposal argue that institutional buying has reduced housing supply and pushed up rents and prices. Critics, however, say that the primary driver of housing inflation remains chronic underbuilding since 2008, combined with population growth, zoning restrictions and high interest rates.
Several analysts also warn that banning large investors could simply shift ownership to smaller landlords rather than first-home buyers, limiting the policy’s effectiveness.
Investors Rotate Back Into AI
While housing and financial stocks weakened, technology and AI-linked equities rebounded strongly. NVIDIA, Microsoft and Alphabet all posted gains as investors returned to the sector following recent concerns about stretched valuations.

Investor enthusiasm was reinforced by reports that Anthropic, the private company behind the Claude AI chatbot, is planning a multi-billion-dollar capital raising that could value the firm at around US$350 billion. Such a valuation would place it above many established blue-chip companies, underscoring the scale of capital flowing into artificial intelligence.
The renewed appetite for AI reflects confidence that productivity gains, automation and data-driven services will continue to generate superior earnings growth compared with traditional cyclical industries.
In relative terms, the Nasdaq’s performance compared with the Dow Jones highlights how capital is increasingly flowing away from industrial, financial and resource stocks toward technology-driven growth businesses.
Economic Data and Federal Reserve Outlook
US economic data released during the session added to market volatility. Job openings fell more than expected in November, while a private payrolls report showed hiring growth in December was weaker than forecast.
Despite the softer data, markets continue to expect interest rate cuts from the Federal Reserve later in 2026, with investors looking ahead to the government’s key non-farm payrolls report due later in the week.
Lower interest rates would typically support housing demand and equity valuations. However, Trump’s intervention in the housing market introduces a political overlay that may complicate the normal relationship between rates and property prices.
Investors are also monitoring geopolitical developments after the US seized a Russian-flagged, Venezuela-linked oil tanker, adding to tensions around global energy flows and trade.
Defence and Other Sectors Under Pressure
Beyond housing, defence stocks also fell after Trump said he would not allow dividends or share buybacks by military contractors until they addressed problems in equipment production and delivery.
Shares of Northrop Grumman and Lockheed Martin declined, reflecting concerns that tighter political oversight could restrict capital returns and profit margins in the sector.
These moves reinforce a broader theme emerging in US markets: increased government intervention across housing, defence, and strategic industries, creating new regulatory risks for investors.
Market and Strategic Context
The diverging performance between AI stocks and the rest of the market reflects a growing bifurcation in US equities. While technology firms benefit from global digitalisation and data-driven growth, traditional sectors face rising political scrutiny, labour costs, and regulatory complexity.
Housing affordability has become a major political issue ahead of the US midterm elections, and Trump’s move to target institutional investors signals a willingness to confront Wall Street even at the risk of market disruption.
At the same time, AI continues to attract vast pools of global capital, with investors betting that the technology will reshape industries ranging from healthcare and finance to manufacturing and defence.

Outlook
With US equities near record highs, political risk rising, and investors crowding into a narrow group of technology leaders, markets are entering a period of heightened sensitivity to both economic data and policy signals.
Trump’s proposed ban on corporate home buying has already rattled property and financial stocks, while the resurgence of AI-driven investing continues to support the Nasdaq.
For investors, the coming months are likely to be defined by how effectively policymakers balance affordability, growth and market stability, and whether the AI-led rally can continue to offset increasing volatility across the broader US economy.
