Cartenna Capital, LP holds a diversified book of 35 reported positions worth $2.7B as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter Space Exploration Techn-CL A first appears in 13F filings, a listing rather than a purchase; they opened 3M Co and trimmed Lam Research Corp. Their largest long position is 3M Co at 7% of the reported non-option book. They also disclosed $1.1B in put options (a bearish bet) and $351.9M in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2021 would be +128% (+15.9%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +145.1%, a 17.6-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Cartenna Capital, LP's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 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.
Top-heavy: diversified book

13F filers disclose option positions at the market value of the underlying the contracts reference, not the premium paid. 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 non-option book, weighting, concentration and sector figures above.
