MOLECULIN BIOTECH INC (MBRX)
Institutional ownership reported to the SEC as of Q2 2026, across 31 quarters.
Institutions report 185,784 shares against 19,477,380 outstanding. Shares only - option lines are excluded, which is why this can be compared with the company at all. The count comes from the cover page of the company's own most recent report, so it is dated when that was filed rather than at quarter end.
Options share is the part of reported value carried in derivative lines rather than shares. A high figure means institutions are expressing a view on this security without owning much of it.
