Source: the manager's quarterly holdings filings with the SEC, via EDGAR. Disclosed long US positions only, not the fund's complete portfolio. Option rows show the UNDERLYING notional value the SEC requires, not premium paid: a put is bearish exposure, and notional overstates the actual bet. Educational analysis of published data. Insight, not advice.
