## Quick answer

CaymanBot turns quarterly 13F filings into a research-friendly view of institutional positions and changes. Compare fund holdings over time, inspect additions and reductions and connect each security with broader ownership and market context.

## Key points

- **Position changes:** Compare reported holdings across quarters to find additions, reductions and exits.
- **Fund research:** Review securities associated with tracked institutional investment managers.
- **Cross-check signals:** Study fund ownership beside SEC insider and congressional disclosures.

## What is a 13F filing?

Form 13F is a quarterly holdings report filed by institutional investment managers that meet the SEC reporting threshold. It lists certain long U.S.-listed securities and commonly includes the issuer, security class, CUSIP, market value and share or principal amount as of the quarter end.

A 13F is not a complete or current portfolio. It arrives after the reporting date, excludes many asset types and generally does not reveal short positions or the investment thesis behind a holding. CaymanBot makes the disclosed long holdings easier to compare while keeping those limitations visible.

## How to read quarterly holding changes

The most useful question is often not “what does this fund own?” but “what changed?” A new position, large increase or complete exit can guide further research. Changes can also reflect portfolio rebalancing, mergers, option exercises or reporting differences, so they need context.

- Compare consecutive quarters rather than viewing one filing in isolation.
- Measure a position relative to the disclosed portfolio, not only by dollar value.
- Account for stock splits, mergers and price changes between reporting dates.
- Remember that the filing may be weeks old when it becomes public.
- Use company fundamentals, news and current price action to validate a thesis.

## Combine institutional and insider data

CaymanBot’s Big Money view sits alongside congressional transactions, SEC insider filings, news, earnings, charts and options flow. This connected data helps you move from an interesting ownership change to a more complete company review.

Holdings data is based on public filings and may be delayed, incomplete or amended. It is intended for research and should not be treated as a replication of any manager’s current portfolio.

## Frequently asked questions

### How delayed are 13F filings?

Managers generally file after each quarter ends, so disclosed positions can be several weeks old by the time the public sees them.

### Do 13F filings show short positions?

Generally no. Form 13F primarily reports certain long holdings and is not a complete view of a fund’s exposures, hedges or derivatives.

### Can I compare a fund across quarters?

Yes. CaymanBot is designed to surface holding changes and history so additions, reductions and exits are easier to research.
