The cluster is dominated by a single large seller, Assenagon, whose trim is 16x the combined buying. Monitor for further institutional selling or a catalyst that could reverse this trend. The small buyers are too small to signal conviction — the signal is neutral at best.
Executive Summary
Three small asset managers modestly added to their ENTG positions in Q3 2026, while one larger holder, Assenagon Asset Management, trimmed over 65% of its stake, reducing its position by $19.4M. The net institutional flow is heavily skewed toward selling by dollar value, though the buyer count exceeds the seller count.

Key Facts
- 3 small asset managers added a combined $1.2M to ENTG positions in Q3 2026
- Assenagon Asset Management trimmed 65.6% of its ENTG stake, selling $19.4M worth
- Total net institutional flow was -$18.2M (buyers +$1.2M vs. seller -$19.4M)
- All three buyers are asset managers with small absolute position sizes (under $3M each)
- The largest seller's trim alone dwarfs the total buying activity by a factor of ~16x
Financial Impact
Net institutional selling of approximately $18.2M in Q3 2026, driven by one large trim of $19.4M partially offset by three small adds totaling $1.2M
Risk Factors
- The 45-day reporting lag means these positions may have already been unwound since quarter-end
- Small buyer count and small absolute dollar values limit conviction signal strength
- No insider buying or other cross-filing context to corroborate the institutional moves
