ZBIO Zenas BioPharma, Inc.
Executive Summary
Three major passive institutions — Morgan Stanley, Wells Fargo, and Schwab — significantly increased their positions in Zenas BioPharma during Q4 2024, collectively adding $3.1M in new holdings with no institutional selling observed. This cluster reflects strong institutional accumulation, driven entirely by large passive managers entering or doubling down on positions.

Actionable Insight
While the buyers are passive managers (suggesting index-driven flows rather than active conviction), the scale of new positions — especially Schwab’s $972K entry and Morgan Stanley’s 6x increase — signals growing institutional footprint. Traders should monitor for follow-through buying and potential float concentration, particularly if active managers begin to participate.

Financial Impact
