Three client-style notes on the public products of Goldman Sachs Asset Management's Quantitative Investment Strategies team, built from public data and published code. Each ends with a section on what the evidence cannot show.

Part 1 · Absolute Return Tracker (GARTX)

Hedge fund replication since 2008. Ten ETFs explain 89% of its returns; an out-of-sample ETF clone tracks it at 2.0% tracking error and 0.94 correlation and earns the fee back. Best of the liquid replicators, and 0.93 correlated with the S&P 500.

Part 2 · ActiveBeta U.S. Large Cap (GSLC)

Four-factor smart beta since 2015, rebuilt from the published rulebook with two unpublished parameters fitted on 2015–20 and tested on 2021–26. The rules recover 0.40 correlation of active returns; the ETF's 0.9%/yr shortfall traces to quality and low-volatility tilts.

Part 3 · Cross-asset trend & carry vs. Managed Futures Strategy (GMSSX)

A 21-market systematic macro program with volatility targeting and risk parity, 2008–2026: 0.41 Sharpe, −21% drawdown, −0.15 correlation to equities, positive in 2008, 2020 and 2022. A gradient-boosted ML overlay under purged walk-forward validation lost to the simple rule.
