Return from mechanically copying the disclosed 13F equity portfolio after each filing and rebalancing at the next. The vs S&P 500 figures subtract SPY over that manager's own rebalance dates, so both sides cover the same days; both are price return, excluding dividends. Method & limitations.

Options positions
Put = right to sell at strike (a bearish bet). Call = right to buy at strike (bullish via leverage). The notional column shows the underlying market value reported to the SEC, not the option premium paid - these don't add to the long-equity % portfolio above.
