Trump Calls Micron a "Great" Company, the Stock Is Falling 4%

Glowing praise from President Donald Trump has often helped stocks higher. But it’s not helping Micron.

“How about this?” Tump wrote in a social-media post Thursday. “Micron, a GREAT American Company, announced that they are putting in 250 Million Dollars into the Trump Accounts for the future benefit of children . . . Thank you Micron!”

The memory-chip maker was falling early Thursday, down 4% at $990.3, after a sharp 10.6% drop in the previous session. The move came despite its rivals SK Hynix and Samsung tumbling in South Korean trading Thursday.

Intel and Nvidia were also falling.

Trump’s support isn’t the reason for the fall. Broader technology sector weakness has hit some of the year’s hottest stocks—and Micron is certainly one of those, up 262% in 2026.

Micron announced a $250 million investment in Trump Accounts earlier this week, tax-advantaged savings accounts for children under 18. Those born between 2025 and 2028 will receive a $1,000 deposit from the Treasury Department.

“Micron, a truly GREAT American Company, and one of the ‘HOTTEST’ anywhere in the World, has announced a HISTORIC $250 MILLION Investment in TRUMP ACCOUNTS,” Trump wrote in a post on Truth Social Wednesday.

But it’s not been a great week to be a hot stock, or a hot stock market for that matter.

South Korea’s KOSPI index tumbled Thursday as the tech selloff that ravaged U.S. markets spread overseas.

The index finished trading down 7.9% Thursday. It’s a hostage to its biggest constituents—memory-chip players SK Hynix and Samsung, which dived 14.6% and 9.1% respectively.

The two are major competitors to Micron, which was down another 2.4% to $1,007.88 ahead of the open Thursday.

The move could just be a brief blip in what has been a stellar year for the KOSPI and Micron. The South Korean index remains up 81% in 2026—that compares with a 9.3% rise for the S&P 500 year to date.
