What Thesis Tracker does

Thesis Tracker is a specialized tool designed for investors and analysts who need to maintain and update investment theses for their portfolio positions and watchlist stocks. This skill allows users to define or load existing theses, ensuring that they have a structured approach to evaluating their investments. By capturing essential elements such as company name, position type, core thesis statement, key supporting arguments, risks, catalysts, target prices, and stop-loss triggers, users can create a comprehensive overview of their investment rationale.

Once a thesis is established, users can easily update it with new data points or developments. The skill prompts for the date of the new information, the nature of the change, its impact on the thesis, and any necessary actions to take. This systematic approach helps investors stay informed and responsive to market changes, enabling them to adjust their strategies based on real-time information.

Additionally, Thesis Tracker includes a scorecard feature that allows users to maintain a running assessment of their thesis pillars. This scorecard tracks original expectations against current statuses and trends, providing a clear visual representation of how each aspect of the thesis is performing. Users can also keep a catalyst calendar to monitor upcoming events that may affect their investment theses, ensuring they are prepared for potential market movements.

The output of the skill is designed to be concise and suitable for various contexts, including morning meetings, portfolio reviews, and risk committee presentations. By providing a structured format for thesis summaries, users can effectively communicate their investment rationale and conviction levels to stakeholders.

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
