New York, Jan 18, 2026, 20:58 EST — Market closed.
Tower Semiconductor’s shares on the U.S. market climbed 4.7% Friday, ending at $129.83. The stock now sits just shy of its 52-week peak. 1
That momentum hits a break as U.S. stock and bond markets close Monday for Martin Luther King Jr. Day. Normal trading will pick up again Tuesday. 2
Why it matters: extended weekends tend to amplify momentum in smaller chip stocks, which often reverses quickly when normal trading volumes resume. Tower’s upcoming moves hinge more on the calendar than on fresh headlines.
Tower, an Israel-based specialty chip foundry, manufactures chips on contract for other firms. Its client base mainly spans automotive, industrial, and various other “real economy” electronics sectors. 3
Interest rates remain steady for now. San Francisco Fed President Mary Daly emphasized that policymakers must be “deliberate” in adjusting policy, noting that “policy is in a good place” to adapt as the economy changes. The Fed’s upcoming meeting is set for Jan. 27-28. 4
Semiconductor manufacturing grabbed headlines again over the weekend as Micron revealed it had signed a letter of intent — a preliminary deal — to acquire Powerchip’s P5 fab site in Taiwan for $1.8 billion in cash. 5
Such a deal doesn’t move Tower’s order book, yet it keeps attention locked on capacity, pricing, and which players are actually investing in factories once more.
Tower hasn’t set a date yet for its upcoming quarterly earnings. Nasdaq’s calendar lists Feb. 9 for now, but that’s just a placeholder until Tower makes an official announcement. 6
Still, the setup can backfire. Should yields climb once more, or if buyers grow wary about industrial and automotive demand, the stock could shed gains just as fast after a strong rally.
Traders will be focused on Tuesday’s reopening to see if momentum holds, then shift their attention to the Fed meeting scheduled for Jan. 27-28 as the next major macro event.
