3 tech stocks moving markets this week

1. Micron Technology (NASDAQ:MU)

Micron Technology reported earnings for its first fiscal quarter of 2026 on Thursday (December 18), showing strong results driven by surging high-bandwidth memory sales for AI data centers

Revenue reached US$13.64 billion, up 93 percent from last year and higher than the company’s September revenue projection of US$12.8 billion. Adjusted earnings per share were US$4.78, beating estimates of US$3.95. The company generated strong free cashflow and declared a US$0.115 per share dividend payable on January 14, 2026.

Looking ahead, Micron adjusted its profit guidance for the upcoming quarter to US$8.42 per share, higher than Wall Street’s US$4.78 consensus, due to continued AI boom momentum.

Investors responded to the results by sending Micron shares up 10 percent post-earnings. Momentum carried into Friday’s trading session, spilling over into other tech stocks, which have come under pressure in recent weeks over lofty valuations and funding concerns. The company ended the week 0.58 percent higher.

2. Trump Media & Technology Group (NASDAQ:DJT)

Trump Media & Technology Group rose nearly 30 percent before Thursday’s opening bell after the company announced plans to merge with fusion power company TAE Technologies.

The all-stock deal is reportedly valued at more than US$6 billion. Devin Nunes, chair and chief executive of Trump Media, and Dr. Michl Binderbauer, CEO and director at TAE, are set to serve as co-CEOs.

TAE is a private company with backing from Alphabet (NASDAQ:GOOGL) and other companies. The merger is slated to create one of the first publicly traded nuclear fusion companies. “We’re taking a big step forward toward a revolutionary technology that will cement America’s global energy dominance for generations,“ Nunes said.

Shares of Trump Media closed the week with a gain of 39.53 percent.

3. Oracle (NYSE:ORCL)

Oracle shares dropped 5.4 percent on Wednesday (December 17) after a Financial Times report claimed data center investor Blue Owl Capital pulled out of a US$10 billion financing round for one of the AI data centers Oracle is constructing for OpenAI in Michigan. Talks reportedly stalled due to concerns over project delays, tougher debt terms, Oracle’s rising debt load and lease arrangements, per sources cited by the news outlet.

Oracle disputed the report’s implications, stating that Michigan negotiations are “on schedule” without Blue Owl.

The company said its project development partner, Related Digital, has chosen “the best equity partner from a competitive group of options, which in this instance was not Blue Owl.” Still, the company finished the week with its share price ahead by 2.18 percent as tech stocks staged an end-of-year comeback.
