The cluster is small and stale (Q3 2026 data). Monitor upcoming 13F filings for Q4 2026 to see if the buying trend continued or reversed. The lack of insider buying (no Form 4 confluences) weakens conviction in the bullish thesis.
Executive Summary
Three institutional buyers added $939K in ACCO positions during Q3 2026, led by Assenagon Asset Management's $824K increase, while Robeco trimmed $1.1M. The net institutional flow is modestly positive but the cluster is small and stale (45-day lag).
