The U.S. stock market in New York experienced a 'Black Friday,' with technology stocks broadly declining, led by semiconductor names. Intel plunged more than 28%, while SanDisk and AMD also posted double-digit losses. Weakness extended to Nvidia and Micron Technology, concentrating selling pressure across the semiconductor sector, and mega-cap tech stocks such as Apple, Amazon, and Microsoft were not spared from the downturn.

Intel Plunges 28.58%, the Biggest Drop Among Semiconductor Stocks

As of the market close on the morning of the 31st Korean time, Intel (INTC) finished at $65.76, down $26.31 from the previous day, a decline of 28.58%. Trading volume was 455,599,430 shares with a traded value of $29.89 billion. Intel recorded the steepest decline among major semiconductor stocks, and with its share price falling more than 20% in a single day, it drew market attention alongside the moves in other semiconductor companies' shares.

AMD Down 10.88%, SanDisk Down 13.47%

AMD closed at $504.80, down $61.62 from the previous session, a 10.88% decline, on a volume of 39,697,503 shares and a traded value of $20.096 billion.

SanDisk (SNDK) closed at $1,150.89, down $179.16 from the previous day, a 13.47% decline, with a volume of 17,469,621 shares and a traded value of $20.433 billion.

Nvidia and Micron Also Weak

Nvidia (NVDA), the representative AI semiconductor stock, finished at $204.64, down $9.02 from the previous session, a 4.22% decline, with a volume of 168,386,423 shares and a traded value of $34.484 billion.

Memory chipmaker Micron Technology (MU) closed at $884.74, down $49.53 from the previous day, a change of -5.30%, on a volume of 30,872,693 shares and a traded value of $27.328 billion.

With major semiconductor-related stocks falling simultaneously, the market is now watching not only individual companies' earnings and outlooks but also whether expectations for AI-related investment have already been priced into shares, as a key variable.

Mega-Cap Platform Tech Stocks Fall Less Than 2%

Large-cap tech stocks also declined. Amazon.com (AMZN) closed at $240.35, down $3.44, or 1.41%, on a volume of 104,894,738 shares and a traded value of $24.97 billion.

Apple (AAPL) closed at $344.63, down $4.28, or 1.23%, on a volume of 67,841,555 shares.

Microsoft (MSFT) finished at $521.91, down $8.23, or 1.55%, on a volume of 35,652,049 shares and a traded value of $18.61 billion.

Alphabet Class A (GOOGL) closed at $279.84, down $3.98, or 1.40%, on a volume of 65,695,032 shares and a traded value of $18.411 billion.

Among the top 10 stocks by traded value, Intel posted the biggest decline, followed by SanDisk and AMD. Nvidia and Micron fell 4% and 5%, respectively.

The simultaneous decline of Intel, AMD, Nvidia, and Micron is notable in that major semiconductor companies underwent a significant share price correction on the same trading day. In contrast, the declines in Apple, Amazon, Microsoft, and Alphabet all stayed below 2%, showing a gap in losses between semiconductor-related names and large platform companies even within the same tech category.

Key Variables Ahead

In the U.S. market, upcoming earnings releases from major tech companies, AI infrastructure investment plans, and profitability outlooks are cited as variables that could influence investor sentiment. With volatility in semiconductor stocks expanding, attention will focus on whether major names rebound in the next trading session and on changes in trading volumes.
