Source. Derived from SEC Form 13F-HR filings retrieved from EDGAR. Rock Group is not affiliated with, endorsed by, or acting on behalf of any institution or fund named on this page.

Timing. A 13F reports holdings as of the quarter end and is due 45 days later, so a position shown here can be several months old. It is a point-in-time snapshot and does not show trades made after the quarter closed. Filers may also amend earlier filings, which restates history — a figure that changes between visits is an amendment, not an error.

Not advice. This page is published for research and informational purposes only. It is not investment advice, not an offer or solicitation to buy or sell any security, and not a recommendation of any institution, fund or strategy. Figures are provided without warranty of accuracy or completeness — verify against the original filing before relying on any of them.
