Astera Labs (ALAB) rose 5.1% in premarket trading following Mizuho analyst defense of its stock amid a new Amazon-Nvidia NVLink Fusion partnership for Trainium4. The analyst argued the collaboration is "additive" for Astera, highlighting higher dollar content potential and clarifying that UALink remains a core option in Amazon’s AI infrastructure. This countered initial market concerns that the partnership would reduce Astera’s exposure. Additionally, recent institutional buying by major firms like BlackRock and positive analyst ratings (e.g., BNP Paribas Exane’s $225 target) reinforced optimism, despite insider sales and a prior 13.5% decline. The rebound reflects renewed confidence in Astera’s NVLink integration and AI infrastructure positioning.
