The $509M in institutional selling, particularly Parnassus' full exit of $341M, signals concern about Marsh's earnings quality given the large GAAP miss from Greensill litigation and restructuring charges. However, Ninety One UK's $300M addition and Vontobel's $43M doubling show conviction from other active managers. Monitor Q4 2026 earnings for resolution of the noteworthy items and whether the selling trend continues.
Executive Summary
A mixed institutional cluster in Marsh & McLennan for Q3 2026: 7 buyers added $348M in new positions (led by Ninety One UK's $299.7M increase and Vontobel's $42.9M addition), while 4 sellers exited or trimmed $509.1M (led by Parnassus Investments' full $341.3M exit and Assenagon's near-$106.5M exit). The selling outweighed buying in dollar terms, and the cluster follows an earnings report where GAAP EPS missed consensus by 23.5% due to large charges, though adjusted EPS beat by 3.6%.
