Ownership.
Large-shareholding trajectories, the raw shareholding filings behind them, and investor (filer) views, sourced from EDINET large-shareholding reports (大量保有報告書).
Overview
Built from EDINET 大量保有報告書 (large-shareholding reports): the raw shareholding filings, the position trajectories assembled from them, and investor (filer) views that roll positions up by holder. The same surface carries the derived ownership intelligence (movers, signals, cross-holdings, and probability tables) computed on top of those trajectories.
