Big Tech Sell-Off Pulls Wall Street Indexes Lower Amid Interest Rate Concerns

Wall Street saw a significant pullback on Tuesday, surrendering recent gains as a sell-off in major technology companies spread from Asian markets to the U.S. Investors are increasingly concerned about the possibility of higher interest rates by the end of the year, which could dampen economic growth and impact company valuations.

The S&P 500 index fell 1.4%, ending a streak of eleven weekly gains out of the last twelve, largely driven by technology stocks. The Nasdaq composite, heavily weighted with tech companies, dropped 2.2%. The Dow Jones Industrial Average, which is less exposed to tech giants, closed just 0.1% lower after an early gain.

Markets in Asia also experienced sharp declines, with South Korea's Kospi index, a notable beneficiary of the artificial intelligence boom, plunging 10%. European stocks followed suit, contributing to a global market downturn.

The current sell-off primarily targeted companies whose valuations have surged due to enthusiasm surrounding artificial intelligence. These high-value stocks exert significant influence over the direction of the broader market. Although more stocks gained ground than fell within the S&P 500 on Tuesday, the losses in technology companies outweighed gains in other sectors.

Notable decliners included Micron Technology, which slumped 13.2%, and Nvidia, down 4.1%. In South Korea, Samsung Electronics fell 12.3%.

SpaceX, however, saw its stock price increase by 1% by the close of trading after wavering in early activity. The space exploration and AI company, which recently had a notable market debut, plans to raise capital through a bond offering, partly to finance its AI development efforts.

The growing probability of interest rate hikes by the Federal Reserve has contributed to the cooling of the significant run-up in AI-related stocks. Traders are wary that higher rates could impede future investment and economic expansion. CME Group data indicates that Wall Street now perceives an 85% probability of a benchmark interest rate increase this year, up from 60% a week prior. The Federal Reserve has signaled potential for at least one rate increase before the year's end.

Analysts have cautioned that the rapid ascent of technology stocks might be due for a correction. "Viewed through this lens, a period of consolidation is reasonable, in our view, after such a sharp move higher," wrote Brock Weimer, investment strategy analyst at Edward Jones, in a research note.

Many technology firms are making substantial investments in AI. The prospect of higher interest rates could constrain future spending and negatively affect asset prices. This concern is amplified by persistent inflation, which has been exacerbated by tariffs and rising energy prices due to the U.S. war with Iran. The cost of shipping has also increased, impacting businesses and consumers. A forthcoming report is expected to show that the Fed's preferred inflation measure rose to 4.1% in May.

Oil prices have seen some easing amidst ongoing negotiations between the U.S. and Iran aimed at ending the conflict. U.S. crude for August delivery fell 0.9% to $73.21 per barrel, and Brent crude for September delivery dropped 0.9% to $76.80. However, these prices remain above pre-war levels.

Overall, the S&P 500 closed down 107.33 points at 7,365.46, the Nasdaq dropped 579.56 points to 25,587.04, and the Dow lost 45.87 points to finish at 51,666.84.
