Stress test
The verified track record answers what did happen. This page answers what would happen: a behavioral policy derived from this trader's chain, played day-by-day against market regimes they haven't traded through. One deterministic path per regime, with no Monte Carlo, no distribution, and no fan chart. A single causal story you can audit.
Edge degrades in regimes the strategy didn't train on, slippage widens with vol, and the policy sits out under drawdown. These are the standard failures of real trading reflected back at simulation speed. Behavioral simulation, not investment advice.
Regime
Compare all regimes →Calendar-year 2008. Calibrated to match the published SPY record: approximately -37% total return, peak drawdown near -48%, realized annualized volatility around 41% with a spike near 80% in October.

What happened
Composed deterministically from the policy decisions. The same input always yields the same paragraph, with no LLM, cached forever.
Run against the 2008 Global Financial Crisis (historical-calibrated regime over 252 trading days). The behavior policy derived from this trader's chain produced a +2.8% total return with a 2.0% peak drawdown; 76 days to recover from the worst trough. The policy entered 9 times, exited 8 times, and sat out 0 days under drawdown / vol thresholds. Policy thresholds: 10.0% profit target, -6.3% stop loss, 10% of equity per position, active on ~30% of trading days. This is a single deterministic path — no Monte Carlo aggregation. It shows what the policy would do in this specific scenario, not a distribution. It is not investment advice.
Key decisions
- Day 38Hit stop loss (-10.9% over last 10 days, vol-adjusted threshold -10.4%).
- Day 46Equity trough: $98,037.
- Day 175Sep 15: Lehman Brothers bankruptcy
- Day 193Oct 9: panic close, -7.6% on the day
- Day 220Nov 19: bear capitulation, peak realized vol

Adversarial resilience
How much of the edge survives a competitor who knows the playbook and fades the policy's fills, hardest on forced stop exits. A resilience disclosure, not a verdict on the trader.

Against a competitor who knows this playbook, the strategy retains 85% of its edge in the 2008 Global Financial Crisis regime: a +2.8% return becomes +2.4% once the adversary withdraws liquidity on its 17 fills, 6 of them forced stop exits. Higher resilience means the edge depends less on cheap, unopposed execution. This is a resilience disclosure, not a verdict on the trader — a deterministic execution-cost stress, not a prediction.

trough of the path
Your dollars on the same simulated 2008 Global Financial Crisis path, a linear scaling of the policy curve, not a separate simulation. Mirroring is exactly proportional, so the percentage path is identical at every allocation; only the dollar figures change. After-fee figures apply this trader's 25% performance fee on a high-watermark basis (you never pay twice for the same gain). Display only; behavioral simulation, not investment advice.
Investor lens
The same result, read through four investor archetypes. Each weights drawdown, return, recovery, and survival differently. The spread itself is the signal. When the panel disagrees, your own tolerance is the tiebreaker.
Deterministic verdicts. Not allocation advice, just a disclosure of how different profiles would read these numbers.
3 of 4 archetypes lean favourable, 0 lean negative, 1 hold. Lean-favourable but not unanimous — read the individual rationales below.
Preservation
The Capital Preserver
Drawdown weighs heaviest here: 2.0% peak drawdown, recovered after 76 days. Upside of +2.8% total return doesn't offset the capital-at-risk reading.
Growth
The Growth Seeker
Total return of +2.8% drives the reading; the 2.0% drawdown is acceptable cost-of-capture. Note: the policy stayed engaged with 9 entries.
Risk-Parity
The Risk-Parity Allocator
On a risk-adjusted basis the return/drawdown ratio of +1.44 is the read. +2.8% return came at 2.0% peak DD; weight in proportion to that ratio.
Skeptic
The Regime Skeptic
Survivability is the question, not upside. The 2.0% max drawdown and the policy exited 8 times against 9 entries characterise how the policy responds when the regime turns.
