The unanimous institutional buying, especially Vaughan Nelson's large new position, signals growing conviction. However, 13F filings have a 45-day lag — positions may have been adjusted since quarter-end. Watch for any Q3 earnings or guidance updates that could validate the thesis. Insider buying ($287K) provides mild corroboration.
Executive Summary
Three active asset managers accumulated $78.9M in Avantor (AVTR) during Q2 2026, led by Vaughan Nelson's new $73.2M position. Assenagon and Wealth Enhancement both doubled their stakes. No institutional selling was reported, creating a strong bullish cluster signal.
