US stocks Futures fell sharply Tuesday, pointing to a weak opening on Wall Street. Nasdaq 100 futures fell 2.5%, S&P 500 futures fell 1.3% and Dow Jones futures fell about 0.6%. The biggest pressure comes from technology stocks. The global sell-off in technology stocks spread from the United States to Asian markets, damaging investor confidence.
Investors are starting to worry about an artificial intelligence-driven stock market rally. As Moneycontrol points out, many traders are now questioning whether huge investments in AI will generate enough profits to justify current stock prices. The weakness came after Wall Street fell the day before. The Nasdaq Composite had fallen 1.3% overnight, while the S&P 500 also ended lower as investors sold off major technology stocks.
Korean market crash
South Korea’s stock market took a major hit. The Kospi index plunged 10% and trading was temporarily halted due to excessive selling pressure. Chipmakers are at the center of the selloff. Shares of SK Hynix and Samsung Electronics plunged more than 12%. Reports about the production of artificial intelligence memory chips have raised concerns among investors. According to Moneycontrol, there are reports that SK Hynix may slow down the expansion of AI memory chip production and focus more on traditional DRAM memory products.
The news raised concerns about future demand for artificial intelligence. Asian technology stocks were hit hard. Asia’s technology index fell as much as 5%. The decline ended a strong rally for Asian technology stocks. Asia’s technology index ended an eight-session winning streak. Artificial intelligence trading has become one of the biggest market themes in 2026. Enthusiasm related to artificial intelligence has helped major global stock markets hit record highs this year.
Micron earnings take center stage
Tuesday’s sell-off raised new doubts about those high valuations. Investors are becoming increasingly wary of paying premiums Artificial intelligence related companies. Market attention now turns to Micron Technology. The company’s quarterly earnings report later this week is expected to provide important clues about demand for artificial intelligence memory chips. Micron Technology’s performance may affect the next move of technology stocks. Investors want the latest information on data center spending and overall AI infrastructure needs.
Stock valuation concerns
Concerns about expensive stock valuations are back in the market. According to Moneycontrol, many investors believe that some AI-related stocks may rise too far, too fast. SK Hynix had already experienced a huge rally before the collapse. The stock surged nearly 350% in 2026 before Tuesday’s sharp decline. Signs of excessive speculation are also evident. Margin lending by South Korean retail investors recently hit a record high.
High borrowing levels tend to increase market risk. When investors are eager to sell, heavy use of borrowed funds can make market declines more severe. The sell-off in tech stocks overshadowed positive geopolitical developments. The easing of tensions with Iran has not concerned investors. Oil prices actually moved lower during the market turmoil. Brent crude fell below $77 a barrel.
Global markets weaken
A U.S. policy decision could help reduce worries about the oil market. According to reports, the United States issued a 60-day license allowing Iran to continue selling oil internationally. The move was seen as support for the ongoing US-Iran peace negotiations. The decision helps ease concerns about supply disruptions in global oil markets.
The sell-off in the technology sector is also making waves in European markets, with the Stoxx Europe 600 index falling 0.92% in early trading, dragging other indexes lower and investors seeking a buffer against riskier bets. This was the culmination of broader “risk-off” sentiment and encouraged traders to reduce exposure to growth stocks.
As is the case with most markets; including the S&P 500 and Nasdaq There are concerns that most major AI companies are trading at high valuations with little or no profit on hand. A market collapse in South Korea and subdued sentiment among global chipmakers all contributed to the global sell-off, according to Moneycontrol.
In short, investors are suddenly worried that AI companies may not be profitable enough to justify their huge stock market gains. The concerns sparked a global sell-off in technology stocks and pushed futures sharply lower on Wall Street.
