Where the P&L came from
| Symbol | P&L | % of starting NAV | How it was obtained |
|---|---|---|---|
| AAPL | 777.34 | 0.7773 | exact, from held quantity × price change |
| AMZN | 501.64 | 0.5016 | exact, from held quantity × price change |
| GOOGL | 84.51 | 0.0845 | exact, from held quantity × price change |
| cash drag | — | 0.0498 | Counterfactual estimate: idle cash at each tick multiplied by the market index return into the next tick. It assumes the cash could have been deployed at the market rate, which the agent never attempted — an estimate, not a measured loss. |
Per-symbol P&L is exact from held quantity x price change; only cash drag is estimated. 17 ticks could be paired.

These trades occurred inside the drawdown window. Co-occurrence is not causation and no causal claim is made here.
Decision timing
Not analysed. Only 3 trades; 5 are needed before a timing figure would mean more than luck.

Per unit of exposure the book moved MORE than the market index did.
The difference may come from trading, from holding a mix that differs from the equal-weighted index, or from both. This measure does not separate them.
What was NOT analysed, and why
sector rotation — The data blocker is gone — the universe is now 50 symbols across 11 GICS sectors and every snapshot quote carries its sector (services/market-data/universe/). What is missing is the analysis itself, which is Autopsy 2.0 work rather than a schema gap. It also needs enough real-market history for a rotation to be distinguishable from a few coincidental trades.
thesis failure — decisions.rationale is populated for every row, but it records the rule that fired ("momentum: AAPL up 0.26% since last tick"), not a forward-looking thesis. There is no claim about the future to test against the outcome, so testing one would mean inventing the thesis first.
Provenance
