New York, January 18, 2026, 19:13 EST — Market closed.
- ALAB wrapped up at $182, gaining 4.3%, following a wide trading range between $177.67 and $187.98
- U.S. markets are closed Monday for Martin Luther King Jr. Day; futures dipped amid new tariff threat headlines
- Company will release its fourth-quarter results on Feb. 10
Astera Labs, Inc. shares ended Friday up 4.3%, closing at $182 as the U.S. market headed into a holiday. The Nasdaq stock fluctuated between $177.67 and $187.98, with trading volume around 5.4 million shares.
After a long break, markets gear up for Tuesday’s reopening following Monday’s Martin Luther King Jr. holiday shutdown of U.S. stocks and bonds. Futures are now the main gauge: Nasdaq contracts fell 1.1%, S&P 500 futures dropped 0.9%, both on light volume. President Donald Trump announced plans to slap extra tariffs on goods from eight European nations starting Feb. 1. Deutsche Bank’s George Saravelos cautioned, “It is a weaponization of capital rather than trade flows that would by far be the most disruptive to markets.” Investors also await delayed U.S. core inflation and consumption data due Thursday, alongside key earnings reports, including Intel’s.

That’s key for ALAB, a fast-growing chip stock linked to the “AI infrastructure” theme. When the market turns wary, these stocks often shift more on positioning than on actual news.
Chip stocks stood out in the last session, with the Philadelphia SE Semiconductor index climbing 1.2% as traders held back ahead of the long weekend. “Most investors will take that as a win,” Ameriprise strategist Anthony Saglimbene said about the market’s flat close. Reuters
Astera Labs plans to report its fourth-quarter 2025 earnings after the market closes on Feb. 10, followed by a conference call at 4:30 p.m. ET. The company specializes in semiconductor-based connectivity solutions aimed at easing bottlenecks between processors, memory, and networking gear in rack-scale AI infrastructure within data centers.

Astera announced in December plans to roll out custom connectivity products for Nvidia’s NVLink Fusion ecosystem, which centers on Nvidia’s high-speed chip-to-chip link. “Hyperscalers are speeding up the rollout of next-gen AI infrastructure,” said President and COO Sanjay Gajendra. Nvidia engineering VP Ashish Karandikar added the partnership offers customers greater flexibility to bring semi-custom AI systems to market more quickly. ASTERA LABS, INC.
Investors are zeroing in on February’s report to gauge demand, driven by cloud giants continuing to pour money into AI servers. The real weight will fall on guidance for 2026, not just the upcoming quarter.
Tariff shocks and wider risk-off moves often target high-multiple semiconductor stocks first, especially right after a holiday when liquidity tends to thin out. Even a small signal that data-center buildouts are slowing or competitors are landing more designs could intensify the sell-off.
Astera Labs stock is set to restart trading Tuesday, with tariff news and a packed U.S. schedule shaping mood. Investors have their eyes on Feb. 10 as the next key date.
