What I want from an investing model
An article-length outline of the non-negotiables in my framework: business quality, valuation discipline, and pre-defined invalidation.
An investing model should reduce decisions, not multiply them. Mine is intentionally boring: a short checklist, a handful of metrics I trust, and explicit “walk away” triggers.
Business quality means durable cash generation and management I can follow without hero-worship. Valuation discipline means I know what I am paying for that durability relative to alternatives.
Invalidation is the part most retail write-ups skip. For every core holding I keep a short list of facts that, if broken, would force a rewrite of the thesis—not a panic sale, a deliberate review.
