Once a strategy is running, improvement ideas never stop coming — and every one looks like it adds return. The hard part: keeping 'looks better' from quietly ruining a strategy that works.
Enhancement ideas, pre-registration, A/B evidence
Numbered, archived research reports — negative results included
Production switches that cleared the bar, and the decision ledger
A human or an Agent proposes an enhancement; motivation, expectations, and pass criteria get logged first.
Before the run, the thresholds are pinned down: risk-adjusted return, drawdown, robustness in the parameter neighborhood.
@quant-eng runs the A/B in the shared framework, including sub-periods and cost sensitivity.
@cio rules by the pre-registered criteria. One round in, all thirteen ideas fell short — including the one it had ranked highest itself.
Rejected ideas become numbered research reports; that rejection ledger later became a differentiator in external pitches.
Every rejected idea's motivation, data, and conclusion stays searchable and reviewable.
Key conclusions get re-verified against alternate benchmarks periodically to catch drift.
When market structure shifts, old ideas get retested against the same bar.
