Positions as reported in the SEC Form 13F-HR filing, valued at quarter-end prices. Weights are each position's share of the reported 13F total, not of the manager's total assets, and say nothing about returns.
A 13F shows US-listed long positions on the last day of the quarter and is filed up to 45 days later. Short positions, cash, bonds and most non-US holdings are not included, and positions may have changed since.
