The cluster is mixed and stale (45-day lag). Monitor upcoming Q3 earnings for fundamental catalysts that may explain the divergence between buyers and sellers. No insider buying to corroborate the bullish side.
Executive Summary
Three asset managers added to IDXX positions in Q3 2026, totaling $43.2M in net buying, while two managers trimmed $69.4M, resulting in a net selling quarter. The cluster shows no insider buying corroboration, and the 45-day reporting lag limits current relevance.
