ASTERA LABS INC
857 institutions still hold ASTERA LABS INC as of Q1 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
Astera Labs' tracked institutional book tells two stories at once, and the first is about price, not conviction: holders whose share count did not budge at all — Chapin Davis, Inc. (11,451 shares, unchanged) and E. Ohman J:or Asset Management AB (3,305 shares, unchanged) — still posted dollar gains of $4.28 million and $1.23 million respectively. That arithmetic implies ALAB's per-share price rose from roughly $110 to roughly $483 this quarter, more than quadrupling. Against that backdrop, fresh capital poured in: at least ten filers opened brand-new positions, led by Mirador Capital Partners LP's $5.68 million stake (11.1% of the tracked book) and Assenagon Asset Management S.A.'s $3.66 million (7.1%), and together with eight smaller new entrants, freshly initiated money accounts for close to a third of the entire $51.2 million tracked total. But not everyone stayed for the ride: StoneCrest Wealth Management sold 91.8% of its shares (7,153 down to 584), Avior Wealth Management sold 86.6% (3,441 to 460), and SteelPeak Wealth sold 79.9% (4,283 to 862) — cuts deep enough that all three posted net dollar losses despite the price surge, the clearest 'getting out' signal in the book. Atop it all sits Wealthcare Advisory Partners LLC, whose $11.0 million stake (21.6% of the total) grew only 0.9% in share count yet still leads the register purely on being positioned before the move; together with Mirador, Chapin Davis, and PensionDanmark Pensionsforsikringsaktieselskab, the top four holders alone control 54% of ALAB's tracked institutional value despite the stock being held by 47 different filers.
