Post-Mortem
A structured review after a position is closed, examining what the thesis said, what actually happened, which assumptions held and which broke, and what was learnable for future work. Post-mortems are the source of compound improvement in an analyst's process over time; without them, the same errors recur because nothing forces the analyst to look back. The discipline is to write a brief post-mortem on EVERY closed position -- winners and losers -- because winners are where overconfidence accumulates.
