Example fit

Use this page when the real job is selection under uncertainty: one momentum sleeve, one crossover sleeve, one regime-conditioned variant, and a need to decide which one deserves further time.

Example candidate set

Trend sleeve

11.4% CAGR · 1.11 Sharpe · WF 0.73. Solid validation and acceptable benchmark-relative behavior.

Fast crossover sleeve

13.2% CAGR · 1.05 Sharpe · WF 0.22. Better headline return, but the holdout support is thin and turnover costs are doing more damage than the first chart suggests.

Regime-conditioned sleeve

10.6% CAGR · 1.18 Sharpe · WF 0.81. Slightly lower headline return, but stronger fold stability and a cleaner story about when the strategy should be allowed to act.

Why the leader wins here

1. Validation survives the sample split
The regime-conditioned sleeve is not the prettiest on CAGR, but its walk-forward average and worst-fold behavior are materially stronger than the fast crossover variant.
2. Benchmark-relative context stays coherent
Its active return remains positive without requiring a suspiciously soft benchmark. That matters more than raw outperformance against one easy proxy.
3. Decision contract stays cleaner
The strategy that deserves the next unit of attention is the one with the fewest unresolved objections. Compare is useful because it makes those objections sit in the same table.
4. The outcome is a workflow action
The leader should move into paper or a stricter saved-result review. The weaker candidates should be dropped or demoted, not carried forward out of optimism.

What compare still does not settle

Forward drift

Compare only tells you which historical case is cleaner right now. It does not replace the paper layer that tests whether the winner still behaves coherently after promotion.

Economic benchmark judgment

Benchmark-aware compare helps, but it does not remove the need to choose a defensible opportunity set. A technically tighter basket can still be economically wrong.

Execution feasibility

Turnover, cost, and benchmark checks make the workflow harder to game, but they still do not replace broker-side implementation design.
