How to read Schedule 13 ownership changes
Schedule 13G/13D reports beneficial ownership at an observation date. “Accumulation” or “reduction” is inferred from changes in reported shares when available; it is not a list of individual trades or exact execution prices.
Form 13F rows are quarter-end holding context only and do not establish an exact entry date.
For more context, see how to read a Schedule 13G, filing date vs event date, or Schedule 13G vs Schedule 13D.
