PASITHEA THERAPEUTICS COR (KTTA)
Institutional ownership reported to the SEC as of Q2 2026, across 21 quarters.
Institutions report 16,787,324 shares against 33,414,448 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.
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.
