Fund Positioning Data: Cross-Holder Crowding from SEC N-PORT + ETFs (Live Sample)

Reading Time: 2 minutes

Hedge funds pay for positioning data — which names institutions are crowded into, which they’re exiting, and where consensus is building. Most of that insight is hiding in plain sight in SEC N-PORT filings and ETF constituent data. The hard part is turning raw holdings into a usable dataset. Here’s what a clean fund-positioning data feed looks like.

Cross-holder crowding (live sample)

Security-level positioning from SEC N-PORT + ETF constituents — how many funds/ETFs hold each name, the consensus label, and the aggregate index weight behind it. Real data:

A sample of the crowding feed. The full product adds period-over-period position-change deltas.

The metrics on top of raw holdings

  • crowding_score — how many distinct funds / ETFs hold the name (consensus vs idiosyncratic).
  • positioning_label — broad consensus · moderately held · idiosyncratic.
  • etf_aggregate_weight_pct — total index weight standing behind a security.
  • delta_signal — new initiation · full exit · accumulated (±Δ%) · distributed (±Δ%), computed period-over-period from prior captured snapshots (no look-ahead).

Who uses fund-positioning data

  • Long/short equity — who’s accumulating or exiting your names, and how crowded a thesis already is.
  • Quant / factor funds — ownership, crowding, and concentration as factor inputs.
  • ETF strategists & IR teams — index weight and holder breadth behind a security.

How it’s sourced (and the fine print)

Built from SEC Form N-PORT (mutual-fund / ETF holdings) and publicly published ETF constituent data, normalized to one schema; crowding is distinct-holder count across the tracked universe and deltas are computed from consecutive captured snapshots. N-PORT public holdings post on the standard filing calendar (a positioning feed, not an intraday tape). Public-domain SEC data — not investment advice, not affiliated with or endorsed by the U.S. SEC.
