Executive Summary
Mixed institutional activity in MELI during Q3 2026: four small asset managers added $12.3M in positions, while four larger holders trimmed or nearly exited $113.6M. The net selling pressure is dominated by Assenagon's $70.7M trim and Ninety One UK's near-exit, suggesting cautious positioning among active managers despite continued accumulation by smaller advisors.
