How we work

The methodology

Every strategy in the database is structured the same way, so you can see the reasoning, not just the result.

  1. 1

    Assumptions

    Regime, edge and data assumptions made explicit up front.

  2. 2

    Model

    Signals, portfolio construction and the risk model.

  3. 3

    Constraints

    Turnover, capacity and the real implementation limits.

  4. 4

    Evaluation

    Backtest design, overfitting checks and out-of-sample tests.

  5. 5

    Monitoring

    Live diagnostics, and knowing when to stop or adapt.
