Methodology: turnover is min(value bought, value sold) ÷ average reported value across the two quarters — value-based, so market moves inflate it slightly versus a share-based measure. Concentration and largest position are shares of the filing’s total reported value, options excluded, with multiple share classes and repeated sub-manager rows for the same issuer combined into one position — the same rule the holdings table uses by default. New/exited counts compare against the prior filed quarter. All figures derive solely from the fund’s 13F filings.
