The cluster is small in dollar terms ($1.4M net buying) and consists solely of asset managers, not activist or event-driven funds. The buying aligns with the Q3 earnings beat but is not large enough to signal a major thesis change. Monitor next quarter's 13F for follow-through from larger holders like BlackRock ($132M) and Dimensional ($91M).
