About Track13F

Methodology, data sources, and the fine print.

What we track

Track13F is a public database of Form 13F-HR filings submitted to the SEC by US institutional investment managers. Each filing discloses long equity positions held as of the last day of a calendar quarter.

How we build it

  1. Poll the SEC EDGAR full-text search and filings API every hour for new 13F-HR and 13F-HR/A submissions.
  2. Parse the XML information table, validate CUSIPs, and normalize to tickers using an internally maintained mapping.
  3. Compute portfolio-level metrics: concentration, turnover, new positions, sold positions, and implied quarterly return.
  4. Cross-reference filers with our investor profiles to attribute funds to portfolio managers.

Limitations

  • 13F discloses only long US equity positions.
  • Filings can lag actual trades by up to 45 days.
  • Reported values use the quarter-end closing price — positions may have moved significantly by the time filings are public.
  • Confidential treatment requests can delay or redact specific positions.

Frequently asked questions

Common questions about 13F data and how Track13F presents it.

What is a 13F filing?

A 13F is a quarterly SEC report that institutional investment managers with over $100M in qualifying assets must file 45 days after each quarter-end. It discloses long US equity positions — no shorts, no bonds, no private holdings.

How do we source data?

We pull raw 13F-HR submissions from the SEC EDGAR full-text search and filings API, parse the information table, and normalize CUSIPs to tickers using an internal mapping table updated monthly.

How often is data updated?

Directory pages refresh hourly. The recent-filings feed refreshes every 5 minutes during heavy filing windows (roughly Feb 15 / May 15 / Aug 15 / Nov 15). Trending and aggregate pages refresh every 30 minutes.

How do you compute returns?

Annualized and quarterly return estimates are computed from reported position values, adjusted for entries and exits. Returns are approximate — 13F data excludes cash, shorts, and non-equity exposure.

Why do some pages show N/A or look sparse?

Funds with fewer than 1 filing, AUM under $100M, or insufficient cross-filer coverage are intentionally light to avoid misleading readers. These pages are marked noindex until more data is available.

Is this investment advice?

No. Track13F is an informational research tool. 13F data lags by up to 45 days and does not capture a filer's complete economic exposure. Do not use this site as a sole basis for investment decisions.
