GREENIDGE GENERATION HLDGS INC CLASS A COM (VIP)
Institutional ownership reported to the SEC as of Q2 2026, across 14 quarters.
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.

Five percent filings
