Thesis Tracker

Workflow

Step 1: Define or Load Thesis

If creating a new thesis:

  • Company: Name and ticker
  • Position: Long or Short
  • Thesis statement: 1-2 sentence core thesis (e.g., "Long ACME — margin expansion from pricing power + operating leverage as mix shifts to software")
  • Key pillars: 3-5 supporting arguments
  • Key risks: 3-5 risks that would invalidate the thesis
  • Catalysts: Upcoming events that could prove/disprove the thesis (earnings, product launches, regulatory decisions)
  • Target price / valuation: What's it worth if the thesis plays out
  • Stop-loss trigger: What would make you exit

If updating an existing thesis, ask the user for the new data point or development.

Step 2: Update Log

For each new data point or development:

  • Date: When this happened
  • Data point: What changed (earnings beat, management departure, competitor move, etc.)
  • Thesis impact: Does this strengthen, weaken, or neutralize a specific pillar?
  • Action: No change / Increase position / Trim / Exit
  • Updated conviction: High / Medium / Low

Step 3: Thesis Scorecard

Maintain a running scorecard:

Step 5: Output

Thesis summary suitable for:

  • Morning meeting discussion
  • Portfolio review
  • Risk committee presentation

Format: Concise markdown or Word doc with the scorecard, recent updates, and current conviction level.

Important Notes

  • A thesis should be falsifiable — if nothing could disprove it, it's not a thesis
  • Track disconfirming evidence as rigorously as confirming evidence
  • Review theses at least quarterly, even when nothing dramatic has happened
  • If the user manages multiple positions, offer to do a full portfolio thesis review
  • Store thesis data in a structured format so it can be referenced across sessions
