After filingAt quarter endBenchmark · S&P 500
After filing — buys the holdings only once the filing is public — about 45 days after the quarter ends. The path someone could actually have taken.
At quarter end — pretends the same holdings were bought on the last day of the quarter, before anyone could have known them. Not possible in reality — shown dashed for comparison only.
Benchmark — S&P 500 (SPY) total return over the same window — what doing nothing but holding the market would earn.
Hypothetical backtest — not a real trading record. Simulated on public data from 2013-08: each position is bought only after the filing became public (using no information unavailable at the time), with trading costs deducted, on a total-return basis. Past performance does not predict future results.

Risk
13F is partial — Multi-strategy + market-making, highly levered and fast-turnover with large option notionals; the filed longs are far from the true net exposure.
The replication is built from public filings: ~45-day lag, US long stock positions only; replication returns are not the fund’s real returns, and the manager may have traded since.
