Matching position names
Historical holdings reports are not a real-time portfolio. Security-level matching (CUSIP/ISIN) distinguishes a company’s bonds, common shares, preferreds and derivatives; issuer-level matching groups them by name or ticker and is labelled as such. See the overlap tool to compare two portfolios.
