BLUE WTR ACQUISITION CORP. I (BLUW)
Institutional ownership reported to the SEC as of Q2 2026, across 6 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.
