how can i track what hedge funds are buying?

follow their quarterly 13F-HR filings on SEC EDGAR. compare each fund's holdings quarter over quarter to see new positions, adds, trims, and exits. for timeliness, monitor filings as they hit EDGAR rather than waiting for an aggregator to update.

is tracking hedge fund positions free?

yes, using SEC EDGAR directly. every 13F is public and free. paid tools add convenience — CUSIP resolution, quarter-over-quarter diffs, and alerts — but the underlying data costs nothing.

how current is hedge fund position data?

13F holdings are reported as of quarter-end and can arrive up to 45 days later, so the freshest you can get from a 13F is the filing date. the way to stay current is to read filings the moment they land, not days afterward.

how do i find a specific fund's holdings?

search the manager's name on SEC EDGAR, filter to form type 13F-HR, pick the quarter, and open the information table. that lists every long US position the fund reported for that quarter.

what's the best way to spot a new position early?

watch the EDGAR feed during the 45-day filing window — especially the deadline days, when most funds file — and diff each new 13F against the fund's prior quarter. new CUSIPs that weren't there last quarter are fresh positions.

How to track hedge fund positions using SEC 13F filings

what public 13F filings let you see, what the 45-day lag hides, and how to catch a new position the moment it hits EDGAR.

by hedgewatch researchpublished june 22, 202610 min read

tracking hedge fund positions means following what the biggest managers buy, add, trim, and exit — and the public record for that is the quarterly 13F-HR filing on SEC EDGAR. the data is free and complete, but it is long-only and up to 45 days delayed, so the edge is less in what you read than in how fast and how carefully you read it. this guide covers the full workflow: building a watchlist, diffing quarter over quarter, and catching new positions the moment they file.

// key_takeaways

→the source is the quarterly 13F-HR on EDGAR — free, complete, long-only, up to 45 days stale.
→the signal is the quarter-over-quarter diff: new positions, adds, trims, exits.
→normalize first — resolve CUSIPs and verify value with shares × quarter-end price.
→timeliness is the edge: read filings as they land, especially on deadline days.

what_you_can_and_cannot_track

a 13F lets you track every long US equity, ETF, and options position a fund held at quarter-end. it does not show shorts, cash, foreign holdings, or anything traded and closed inside the quarter — the limits are spelled out in what 13F filings don't show. track accordingly: 13Fs are excellent for accumulation and conviction over time, poor for fast directional reads on a single name.

three_ways_to_track

Three approaches to tracking hedge fund positions from 13F data, with their trade-offs.
approach	speed	trade-off
manual EDGAR	as fast as you read	free, but no diffs and no CUSIP resolution
screeners / aggregators	days behind	convenient, but stale and inherit data errors
real-time detection	seconds after filing	needs tooling that polls EDGAR continuously

most public screeners ingest the filing's value field at face value — so they inherit the pre-2023 thousands-convention error and show some real positions 1,000× too small. tracking from the raw filing avoids that.

the_tracking_workflow

1
build a manager watchlist
list the funds you follow and record each manager's CIK for exact matching.
2
pull each quarter's 13F-HR
retrieve every manager's latest information table — see how to find a 13F on EDGAR.
3
normalize the holdings
resolve each CUSIP to a ticker and verify value against shares × quarter-end price.
4
diff against the prior quarter
flag new CUSIPs, larger/smaller share counts, and positions that disappeared.
5
rank by conviction
sort by portfolio weight and position size to find the real bets.
6
monitor in real time
watch the EDGAR feed during the window so a new position surfaces the moment it files.

reading_the_quarter_over_quarter_diff

the diff is where tracking becomes signal. four changes matter: a new position (a CUSIP that wasn't there last quarter), an add (higher share count), a trim (lower), and a full exit. weight each by how large it is relative to the fund's book — a new position at 8% of the portfolio is a far louder signal than one at 0.2%.

the timing wrinkle: because filings cluster at the deadline, the entire quarter's changes tend to arrive in a few days — see the 13F filing deadlines. whoever reads that crush fastest sees the moves first.

tracking_in_real_time

the manual workflow scales to a handful of funds. tracking the whole market in real time — and catching the positions that are hidden by the thousands-convention error — is what HedgeWatch automates. the detector polls SEC EDGAR every 60 seconds during the filing window, parses each 13F-HR as it lands, resolves CUSIPs, verifies every value against shares × quarter-end price, and surfaces new and mis-stated positions with the filing receipts attached. that is the difference between reading last quarter's book days late and seeing a fresh position the moment it files.

the positions worth the most are often the ones screeners render too small to notice. a tracker that verifies value against price — instead of trusting the filing's value field — is the one that surfaces them.
