Reported price = value ÷ shares at the quarter-end — an average, NOT the manager's buy/sell price.
Current shows the stock's price change since the filing quarter-end (mapped names only) — it is the STOCK's move, not the manager's realized return (we don't know their cost basis or whether they still hold).
