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.

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.
