Changes compare each manager’s latest 13F with its prior quarter for the same CUSIP. “First observation” rows have no earlier stored filing to compare and are never counted as buys; “Split?” rows moved by a near-whole factor at an unchanged value and are treated as stock splits, not trades. Ending weight is the position after the change, not the size of the change.
