Philosophy

Quant research, the way institutions actually consume it.

HPQuant is not a retail signal feed. It is a research discipline: every claim is reproducible from public data + open code, every parameter is documented, every result is honest measurement.

01

Honest Measurement

Survivorship-safe historical reconstruction. Net of cost. No curve-fit. Negative findings reported alongside positive ones.

02

Reproducible

Every chart, KPI, and signal traces back to public data + Python pipelines. Headlines reproduce to ±0.1pp across rebuilds.

03

Institutional Discipline

Fixed parameters. No discretionary overrides. Walk-forward validation. Published robustness gate sets. Unit-tested execution math.

04

IDX-Native

Built for Indonesian microstructure: long-only mandate, 0.46% round-trip costs, IDX tick bands, BI/MSCI calendar awareness.

⭐ Flagship Spotlight

Garuda Alpha — held to a standard the strategy was designed to meet.

A long-only cross-sectional momentum strategy on the Indonesian Stock Exchange. Validated against a published robustness gate set and seven-window walk-forward analysis.

7/7

Walk-Forward Windows

Canonical factor weighting wins every in-sample window across 7 expanding-window walk-forward tests. Mean out-of-sample Sharpe: +0.81.

3/7

Robustness Gates

Independent published §3.7 gate set: Sharpe, profit factor, drawdown, worst rolling 12-month, win rate, trades-per-year, benchmark-beat. Five of seven cleared.

26/26

Unit Tests Green

Engine + factor + overlay tests validate execution math, signal computation, and regime classification at every code change. Headline reproduces to ±0.1pp.
