Period Price is the implied market price on the last day of the reporting period, calculated as reported value ÷ shares held. It is not the fund's purchase price or cost basis — the fund may have initiated or added to the position at any point during the quarter at a different price. Since Period shows the price change from that quarter-end snapshot to today's last price — it reflects stock movement after the report date, not the fund's actual return.
