Headwater Capital Co Ltd holds a concentrated book of 14 reported positions worth $493.4M as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter they opened Amazon.com Inc and trimmed Taiwan Semiconductor-SP ADR. Their largest long position is Taiwan Semiconductor-SP ADR at 20% of the reported non-option book. They also disclosed $7.0M in put options (a bearish bet), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2025 would be +86% (+60.1%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +96.1%, a 10.5-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Headwater Capital Co Ltd'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.

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 | $7.0M | 630K |
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.
