A stake quotes the filing or report it links to — a Schedule 13G, a prospectus, or press coverage for private companies — as of that date. A reported position is the holding stated on the person's newest SEC Form 3/4/5 for that issuer, common shares only, split-adjusted; it is as current as their last filing. Neither is investment advice.
