List Unwinding Scoreboard

Cross-shareholdings actively being unwound.

Cross-holdings (持ち合い株) are reciprocal stakes between two listed Japanese companies, historically used to lock in friendly shareholders. Regulatory and governance pressure since ~2018 has pushed many of these pairs to unwind.

This endpoint returns pairs where at least one side shows a clear declining trajectory, ranked by fastest decline. Use it to find forced sellers and identify potential float expansion ahead of secondary supply hitting the market.
