P06-QUANT / INVESTMENT FLIGHT RECORDER
A return curve is not an investment process.
01 / RISK COCKPIT
Risk cockpit
Daily adjusted-close returns; current target weights reset daily from 2020; targets without observable history remain in SHV; 252-session annualization; QQQ benchmark.
Who actually carries the risk?
Marginal contribution to variance over the latest common 252-session window. Twenty-four eligible equities collapse to roughly three independent risk bets.
02 / CAUSAL STRESS
Causal stress laboratory
03 / SCENARIO → WEIGHT
Make 20 / 55 / 25 earn the weights
This is a transparent sensitivity surface, not a recommendation. Production weights remain unchanged.
04 / REBALANCE SEMANTICS
One threshold no longer does two jobs
The historical replay still used max(±25% of target, ±0.75 pp). We disclose it instead of silently rewriting history.
Position risk band ±25% of target; layer band ±20%; execution de-minimis 0.10 pp, applied only after a breach.
05 / POINT-IN-TIME
The honest backtest boundary
- Dated eligible universes and index constituents
- Vintage prices, fundamentals and classifications
- Versioned decisions made only with information available then
Current replay may be used for risk diagnostics only.
06 / PROBABILISTIC VALUE
Probabilistic underwriting sandbox
Fast takeoff
Industrial scaling
Plateau / regulation
Generic sandbox · issuer-specific inputs must come from dated workpapers before any valuation is approved.
07 / FORWARD SCOREBOARD
Forecast outcome ledger
08 / EXIT MAP
A finite six-step track
Publish the external-review receipt and freeze exact calculation definitions.
Render risk and concentration metrics from reproducible files.
Publish causal layer stress assumptions and first-order losses without calling them forecasts.
Make scenario priors mechanically produce a shadow layer mix; no production weights may change.
Replace selection-biased history with a point-in-time eligible universe and publish the vintage ledger.
Connect issuer underwriting to resolved forecasts and publish calibration after sufficient outcomes exist.
