HORIZON SPACE ACQUSTN I CORP (HSPOF)
Institutional ownership reported to the SEC as of Q3 2025, across 11 quarters.
Institutions report 1,737,560 shares against 4,168,739 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. Share count carried from an earlier filing (cy2025q2i).
Calls and puts are the parts of reported value carried in derivative lines rather than shares, and they point in opposite directions: a manager holding calls is positioned for the security, one holding puts against it - or hedging shares they already own, which is why index funds carry so many. Most sites add the two together and report one figure, which averages away the only interesting part.
