Quarterly SEC Form 13F disclosures from the managers Kresmion tracks, not a complete ownership ranking. Non-option holdings only; reported put and call positions are excluded. Different securities are labeled by CUSIP. The share of reported value is each position's value over the sum of the values that manager reported for the quarter; option lines are not in that sum, as on each fund page. Values are reporting-period snapshots, not current position values. Filings can arrive up to 45 days after quarter-end.
