Astera Labs (ALAB) is a component of the WallStreet AI Index (WSAI) in the Semiconductors & Foundries segment, with an index weight of roughly 1.30%.
Why ALAB is in the index
Pure-play AI connectivity silicon (PCIe/CXL retimers) linking GPUs, CPUs and memory inside AI servers.
Its role in the AI value chain
The silicon layer: AI accelerators, the foundries that fabricate them, memory (HBM/DRAM/NAND), storage, chip-design software (EDA), and the equipment that makes advanced nodes possible. This is where AI compute is physically created.
