Wall Street Plunges as Tech Sell-Off Deepens and Nasdaq Slumps

US equity markets faced a significant downturn on Tuesday as a massive sell-off in technology stocks triggered a broad-based decline across major indices. Investors are increasingly pivoting away from high-growth sectors due to rising interest rate expectations and mounting concerns regarding the sustainability of the AI-led rally.

Major Indices Retreat Amid Technology Bloodbath

The US stock market opened on a weak note, with the Nasdaq Composite bearing the brunt of the selling pressure. The tech-heavy index declined by 365.57 points, or 1.40%, to reach 25,801.03, while the S&P 500 dropped 1.02% to 7,396.30. The Dow Jones Industrial Average also succumbed to the downward momentum, falling nearly 200 points to 51,515.02.

The decline was not limited to the major benchmarks; the DJ Total Stock Market Index plunged 733.07 points, or 0.99%, to 73,385.98, signaling that the weakness was widespread across the US equity landscape.

Semiconductor and Big Tech Stocks Lead the Losses

The downturn was primarily driven by a sharp correction in the information technology sector. Semiconductor manufacturers saw the most dramatic hits, reflecting a broader cooling in the hardware and chip-making space. Key movers included:

  • Micron Technology: Dropped more than 11%.
  • Intel: Fell over 7% in overnight trading.
  • Qualcomm: Declined by 6.3%.
  • Memory and Storage: Sandisk slid nearly 9%, while Seagate dropped 7.2%.

Beyond semiconductors, heavyweights such as Alphabet, Nvidia, Oracle, and Tesla all opened significantly lower, extending the losses seen in previous sessions. Even Elon Musk’s SpaceX (via xAI) saw its value slip further, trading near $156 per share, a sharp decline from its recent highs above $200.

Monetary Policy Concerns and Inflation Fears

The primary catalyst for this market volatility is the shifting outlook on US monetary policy. Traders are now pricing in a nearly 90% probability of at least one interest rate hike by the end of the year—a significant jump from the 57% probability recorded just one week ago.

The fear of tighter monetary policy is compounded by upcoming inflation data. Economists anticipate that US consumer inflation for May will rise to 4.1%, up from 3.8% in April. This expected uptick is driving yields higher; the 10-year US Treasury yield settled around 4.49%, up from 4.43% a week earlier.

A Global Synchronized Downturn

The weakness in Wall Street follows a significant downturn in Asian and European markets. South Korea’s Kospi tumbled 10% to 8,203.84, driven by semiconductor concerns and regulatory scrutiny. Japan’s Nikkei 225 fell 3.6%, while European indices like Germany’s DAX and France’s CAC 40 also moved lower.

While equities faced a rough day, commodity markets remained relatively stable. Brent crude traded slightly below $78, supported by the US decision to temporarily waive sanctions on Iranian oil sales, providing a momentary breather in the energy sector.

Key Takeaways

  • Tech Sector Vulnerability: A massive sell-off in semiconductor and AI-related stocks, led by Micron (-11%) and Intel (-7%), triggered a deep plunge in the Nasdaq.
  • Rising Rate Expectations: Markets are pricing in a 90% chance of a US interest rate hike by year-end, fueled by fears of rising inflation.
  • Global Contagion: The US slump is part of a wider global trend, following significant losses in South Korean, Japanese, and European equity markets.
