US stock futures pulled back Tuesday morning after Samsung’s blowout earnings report triggered a wave of selling across the chip sector. The Nasdaq bore the brunt of it, while the Dow held up better.
Samsung reported a 19-fold increase in second-quarter operating income, driven by surging demand for artificial intelligence chips. Despite the massive profit jump, the company’s stock fell nearly 7% in Seoul trading.
Analysts pointed to profit-taking after a 382% surge in Samsung’s stock over the past 12 months. The earnings also only beat estimates by around 6%, which disappointed some investors.
“One theme in the pack is how astonishing moves in the South Korean equity market have been over the last year,” said Deutsche Bank analyst Jim Reid. He noted that South Korea’s benchmark KOSPI index also fell sharply.
The sell-off in chip stocks came just one day after a broad market rally. On Monday, the Dow closed at a record high for the second straight session, while the Nasdaq gained more than 1%.
Nasdaq 100 futures dropped around 1% in pre-market trading. S&P 500 futures fell 0.2%. Dow Jones futures edged up about 0.1%, adding 48 points.

The gap between the Dow and Nasdaq futures showed investors rotating away from tech and into more traditional blue-chip stocks.
