How to Read Taiwan Stock Shareholder Concentration Data
Taiwan Stock DataTaiwan's TDCC (Taiwan Depository & Clearing Corporation) publishes weekly shareholding distribution data, grouping all shareholders by lot size — from 1–10 lots to over 1,000 lots. When the percentage held by large shareholders (400+ or 1,000+ lots) rises steadily, it often signals accumulation by institutions or high-net-worth investors. Declining large-holder concentration may indicate distribution. Blave tracks this weekly data per stock with historical trend charts.
