  • Beta, last 3 months 0.60 about the same as over the year
  • On the 10 worst bond days +0.24% on average against −0.74% for the S&P 500 the 10 sessions of the past year in which TLT fell most, i.e. long yields rose most

Company snapshot — Astera Labs, Inc.

ALAB in five paragraphs: what it makes and sells, where it sits in the Closelooknet stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
Astera Labs builds connectivity chips that link processors, memory and storage inside AI servers, plus retimers, smart cable modules and switch silicon. Its COSMOS software manages and tunes these links across large fleets. Customers are hyperscale cloud operators and server makers who need reliable high-speed links inside AI racks. It is based in San Jose and went public in 2024.
Where it sits in the stack
In our Rubin Build-Out 100 index, Astera Labs sits in Layer 5, Connectivity & Materials, within the High-Speed Interconnects sleeve — the fabric that turns separate GPUs into a working cluster. It is a supplier hyperscalers depend on to keep signal integrity as racks scale, so it is a constraint on how fast clusters can be wired together.
Who it is priced against
Closelooknet's peer group groups it with custom silicon and optical interconnect names — Marvell, Broadcom, Nvidia and Credo Technology — reflecting who the market prices it against rather than shared sector labels. Cisco Systems is the additional networking name sometimes drawn into the comparison.
Why Closelooknet tracks it
It is a Rubin Build-Out 100 constituent and carries a Closelooknet score, strongest on quality and weakest on valuation. The diary has quoted it in a Nvidia ecosystem report on signal and fabric roles, and in Morning 10 and Midday 10 notes tracking interconnect names on volatile trading days.
What the diary watches
Whether interconnect demand tracks the pace of new AI cluster builds, or whether the stock keeps trading as a proxy for how fast that build-out is expected to run.

Astera Labs, Inc. (ALAB) trades on US exchanges, and sits in Layer 5 of the build-out stack. Constituent of Rubin Build-Out 100.
