Frequently Asked Questions

A 13F filing is a quarterly report that institutional investment managers with over $100 million in qualifying assets must file with the SEC. It discloses their U.S. equity holdings — stocks, ETFs, and certain options. These filings are due 45 days after each quarter ends, giving a window into what the biggest funds on Wall Street are buying and selling.

13F data is updated quarterly when hedge funds file with the SEC — typically mid-February, mid-May, mid-August, and mid-November. Insider trading (Form 4) data is updated within two business days of the transaction. Dark pool data is refreshed daily.

Convergence signals fire when multiple independent data sources align on the same stock. For example, if hedge funds are adding new positions and insiders are also buying — that's a convergence. These multi-source signals are our strongest indicators because they reduce the chance of any single data point being misleading.

The SEC gives institutional investors 45 days after quarter end to compile and file their 13F reports. This means Q4 data (ending December 31) won't appear until mid-February. The delay is built into the regulation — it's the same for every platform, not a HedgeTrack limitation.

13F filings only cover U.S.-listed equity securities — stocks, ETFs, and some options. They exclude bonds, foreign stocks, cash, short positions, and derivatives. A fund's real portfolio can look very different from its 13F. Use the data directionally, not as a complete picture.

Dark pools are private exchanges where institutional investors execute large block trades without impacting the public market price. Tracking this off-exchange activity reveals where big money is moving before it shows up in traditional price action. Spikes in dark pool volume on a stock can signal upcoming institutional interest.

We run local LLMs (currently Gemma 3 12B) on-device to generate stock summaries and sentiment analysis. The models process 13F changes, insider filings, and fundamental data to produce a plain-English summary for each stock. No data is sent to third-party APIs — all inference runs locally for privacy.

Yes. HedgeTrack.ai provides a public REST API for available datasets. Higher-limit paid API plans are not live yet. Check the API docs at /api/docs for endpoints and usage.

All data comes from official public sources: SEC EDGAR for 13F and Form 4 filings, and FINRA ADF/TRF feeds for dark pool activity. We don't use any proprietary or paid data vendors.
