Katamaran Capital LLP holds a focused book of 35 stocks worth $117.0M as of Q2 2026 (disclosed Jul 21, 2026, a ~45-day 13F lag). This quarter they opened Booking Holdings Inc and trimmed Visa Inc-Class A Shares. Their largest long position is Visa Inc-Class A Shares at 10% of the equity book. They also disclosed $8.5M in put options (a bearish bet), shown separately below and excluded from the equity book. Cloning the disclosed picks since 2025 would be +13% (+9.0%/yr). That is a simulation of the disclosed long book, not audited returns.

The reported book (valued from quarter-end) returned +27.1%, a 13.7-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Katamaran Capital LLP's disclosed long 13F book, rebalanced on each filing date (so it reflects the ~45-day reporting lag, 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.

Put / call positions from the 13F — totals include every disclosed option leg
| Type | Underlying | Notional value | Underlying shares |
|---|---|---|---|
| PUT · bearish | INVESCO QQQ TRUST SERIES 1QQQ | $8.5M | 12K |
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 equity book, weighting, concentration and sector figures above.
