Dataset
StarterShareholding Concentration (TDCC tiers)
Large-holder vs retail concentration from tdcc shareholding tiers — per row: total holders, 400-lot+ large-holder count/pct, 1000-lot+ large-holder pct, retail pct, and week-over-week delta; sourced from the TDCC.
What this data is
Each row is one stock's concentration for one period, carrying holder_count_total / large_holder_count_400 / large_holder_pct_400 / large_holder_pct_1000 / retail_pct / large_holder_pct_1000_wow_delta (total holders, 400-lot+ large-holder count/pct, 1000-lot+ large-holder pct, retail pct, and week-over-week delta). Sourced from the TDCC, graded derived (computed from official data). Keyed on the data as-of date and point-in-time safe; The backend /v2/datasets meta exposes only grade / tier / point-in-time and no coverage window, so none is stated here.
Use cases
- Watch chip concentration/dispersion via large-holder pct.
- Track large-holder direction via the week-over-week delta.
- Read chip structure and squeeze risk via retail pct.
Why it matters for stock analysis
TDCC tier data needs manual layering; this dataset pre-computes large-holder/retail pct and the weekly delta, point-in-time safe, no manual tiering.
