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 Q1 2024 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.
