Institutional cluster: 4 buyers, 3 sellers (mixed)
Actionable Insight ◆ Mixed

The massive accumulation by Assenagon and Wealth Enhancement suggests a strong conviction thesis, but the simultaneous trimming by Vontobel and near-exit by Td Waterhouse Canada creates ambiguity. Monitor upcoming 13F filings for Q4 to see if the buyers maintained or reversed these positions, and watch for any insider trading patterns that could corroborate the thesis.

Executive Summary

Institutional activity in TER for Q3 2026 shows a mixed picture: two asset managers (Wealth Enhancement Advisory Services and Assenagon Asset Management) dramatically increased their positions, adding a combined $551.7M in new holdings, while three other managers trimmed or nearly exited positions totaling $21.5M in net selling. The cluster is dominated by active asset managers, but the net conviction is mixed given the divergence between large accumulators and sellers.
