How these are measured

Moves since the quarter-end and since the filing date use our own daily closing prices, from the close on (or just before) each date to the latest close.
Turnover is the lesser of shares bought or sold in a quarter, valued at the quarter-end prices in the 13F, divided by the average of the two quarters' stock portfolio values.
Quarters held and add/trim streaks count back only through quarters whose filed holdings add up to the filing's own cover-page total (back to Q4 2025 for this fund). A change counts as an add or a trim when the split-adjusted share count moves by more than 1%.
Estimate, not the fund's reported cost. For each quarter in the current holding period in which the fund's share count rose (split-adjusted), we take that quarter's average daily close and weight it by the shares added; sales do not change an average cost. Quarters where the stock's price history and the 13F's own implied price disagree by more than 2x are left out.
Put and call option rows report the value of the underlying shares, not a position the fund paid for, so they are left out of all of the above.
