What is AVTX institutional ownership?
This page tracks AVTX positions reported by institutional investment managers through SEC Form 13F. AVALO THERAPEUTICS INC (AVTX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own AVTX?
InsiderSet currently tracks 135 institutional managers reporting AVTX holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of AVTX shareholders.
How much AVTX stock do institutions own?

When was AVTX institutional ownership last updated?
The latest AVTX institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
