PBCay One RSC Ltd holds a focused book of 18 reported positions worth $1.7B as of Q2 2026 (disclosed Jul 27, 2026, a ~27-day 13F lag). This quarter Space Exploration Techn-CL A first appears in 13F filings, a listing rather than a purchase; they opened SS SPDR S&P 500 ETF Trust-US and trimmed Amazon.com Inc. Their largest long position is SS SPDR S&P 500 ETF Trust-US at 16% of the reported non-option book. They also disclosed $64.8M in put options (a bearish bet), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2024 would be +39% (+16.5%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +73.4%, a 34.4-point gap that is the cost of the ~27-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning PBCay One RSC Ltd's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~27 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 | SS SPDR S&P 500 ETF TRUST-USSPY | $64.8M | 90K |
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.
