K2 Principal Fund, L.P. (copied at disclosure) S&P 500

The reported book (valued from quarter-end) returned +9.4%, a 2.2-point gap that is the cost of the ~38-day 13F disclosure lag a real follower can't avoid.

Growth of $10,000 cloning K2 Principal Fund, L.P.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~38 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.

A put is a bearish bet (it gains if the stock falls); a call is bullish. “Underlying shares” is the share count the contracts control, not a share holding. These legs are excluded from the equity book, weighting, concentration and sector figures above. Showing the largest 25 of 74 option legs.
