Each position is governed by a written thesis, risk assessment, and exit rule.
Conviction made accountable.
Positions, performance, and decision reviews are organized around evidence, explicit risk, and repeatable process.
Core asset allocation and concentrated long-term compounders are reviewed separately.
Candidates remain in research until evidence, valuation, and structure align.
Post-investment reviews translate execution errors into explicit process changes.

Add level
Increase exposure only when the company and stock confirm the thesis.
03

Exit rule
