13f.info Review, Pricing, and Features
By Jera Value · Verified Sep 2026
13f.info lets you look up institutional investors and compare the holdings they report to the SEC each quarter. Follow a manager, trace a stock's reported ownership, or open the original filing to check a change. A separate Form D search covers private-offering notices. These are historical disclosures, so use them to guide further research rather than copy a live portfolio.
Verdict
Worth it if you want to compare institutional portfolios from quarterly SEC disclosures.
- Ownership research: compare managers and reported position changes
- Source checks: open the original SEC disclosure
Skip it if you need current holdings or complete long-short exposure.
- Reporting lag: 13Fs can arrive 45 days after quarter-end
- Incomplete exposure: shorts and purchase prices are absent
- Data checks: filing errors and corporate actions can distort changes
