The strong buying from sovereign and quant funds suggests a shared thesis around Celestica's AI/data center exposure, but Viking's massive exit and zero insider buying warrant caution. Monitor for any Q3 13F filings that confirm whether these positions were maintained or reversed, and watch for insider open-market purchases as a corroborating signal.
Executive Summary
A large institutional cluster for Celestica (CLS) in Q2 2026 shows strong net buying of $1.50B from 71 buyers, led by sovereign wealth fund Norges Bank ($544.8M new position) and quant funds D.E. Shaw ($404.0M add) and Citadel ($107.5M doubled). However, Viking's full $466.2M exit and a lack of insider buying (0 open-market buyers) create a mixed signal, tempering conviction despite the aggregate accumulation.
