Bought / sold is the change in shares × the quarter's reported price (value ÷ shares in the filing); a position sold out is priced at the quarter before, since it has no price in this one. “Of the portfolio” is that amount against this quarter's reported book.
Source: the manager's Form 13F-HR on SEC EDGAR, kept as immutable quarterly snapshots; changes compare two consecutive filings. A 13F is filed up to 45 days after quarter end and covers US-listed long positions only. Tickers come from a self-maintained CUSIP map; a position without one shows its CUSIP. Method notes in where the numbers come from.
