Portfolio data is normalized using SEC Form 13F filings, including the Restatement filing (0001082917-16-000016, filed 2016.07.26).

From 2023-01-03 onward, the SEC requires values to be reported in nearest dollars. Earlier filings reported values in thousands; therefore, positions shown as $0 in older filings may represent actual values between $0–$999.
