A 13F is a snapshot of the portfolio at each quarter end: it doesn't show the day of each purchase. "Held since" is the first quarter in which the position appears continuously (up to 3 years of history). For this quarter's purchases we show the range of closing prices in the quarter and its average, the best estimate of the purchase price, and how much it has moved since.
