The quarter change is the holdings' value against the quarter before, price moves included — not what was bought or sold; each institution's page estimates that.

Net bought (estimate)

Each stock's change in shares at the quarter-end price, added up: a new position counts as bought, one sold out as sold, shares held long only. Splits are compared split-adjusted; corporate actions under a new CUSIP are not estimated. An estimate from the filings, not actual trades.
