Spider Management Company, LLC holds a concentrated book of 5 reported positions worth $398.2M as of Q2 2026 (disclosed Aug 13, 2026, a ~44-day 13F lag). This quarter they opened Amer Beac GLG NTRL RSRCS ETF and trimmed SS SPDR S&P 500 ETF Trust-US. Their largest long position is SS SPDR S&P 500 ETF Trust-US at 55% of the reported non-option book. They also disclosed $62.0M in put options (a bearish bet) and $33.2M in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2024 would be +21% (+10.9%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +26.2%, a 5.1-point gap that is the cost of the ~44-day 13F disclosure lag a real follower can't avoid.
