Master Diagnostic Engine - Re-usable Prompt

Analyze [TICKER] using the Master Diagnostic Engine framework below.

I am a long-term, moat-first equity investor. Do not make portfolio
recommendations or suggest position sizing unless I explicitly ask.


FRAMEWORK REFERENCE

Visual glossary (apply throughout):

  • Fragile = concave payoff to stressors (accelerating downside)
  • Robust = flat payoff regardless of stressor
  • Antifragile = convex payoff (benefits from disorder)
  • Embedded expectations = the implied growth rate or earnings trajectory the market is pricing into the stock at current price; what has to be true for the current price to be fair value
  • Contrarian's Playbook axes: Market Sentiment (Pessimism ↔ Euphoria) vs. Embedded Expectations (Low ↔ High)
    • Opportunity Zone = pessimism + low expectations
    • Danger Zone = euphoria + high expectations

SECTION 1 — Fragility Spectrum

Identify 3 things [TICKER] is fragile to (concave downside —
stressors that accelerate harm).

Identify 3 things [TICKER] is robust to (flat payoff — stressors
that don't materially change outcomes).

Identify 3 things [TICKER] is antifragile to (convex upside —
disorder or stress that improves the business's position).


SECTION 2 — Skin in the Game

Assess leadership alignment using the three-category filter:

  • Bureaucrat: upside, no downside → REJECT
  • Symmetrical Partner: upside + downside (own capital at risk) → ACCEPT
  • Hero: downside, no upside → N/A

Report founder/CEO/key insider share ownership in dollar terms and
as % of total shares. Note insider buy/sell behavior over the past
2 years. Flag any SBC > 15% of revenue or growing share count despite
buybacks as a management quality concern.

Is leadership operating as a bureaucracy in any material way
(e.g., compensation disconnected from performance, dilutive equity
grants, capital allocation that benefits management over shareholders)?


SECTION 3 — Sentiment & Embedded Expectations

What is the current market sentiment toward [TICKER]?
(Pessimistic / Neutral / Euphoric — with evidence: price vs 52-week
range, YTD return, analyst consensus, recent narrative.)

What are the embedded expectations at the current price? Reverse-
engineer: what FCF growth rate, margin trajectory, or market share
gain does the current price require to be justified at a reasonable
discount rate (use 9–10%)? Is this the optimistic case, base case,
or conservative case?

Map [TICKER] on the Contrarian's Playbook: Opportunity Zone, Danger
Zone, or neither?


SECTION 4 — Master Diagnostic Engine (5 Gates)

Work through each gate sequentially. State PASS or FAIL for each.
If a gate fails, note whether that means DISCARD or WAIT.

Gate 1 — The Asset: Is it a Compounding Machine?

  • Moat archetype(s): Intangible Assets / Switching Costs / Regulated Workflow / Network Effects / Negative Working Capital / Cost Advantage. Is the moat durable and AI-resistant or AI-threatened?
  • Reinvestment runway: Is there a credible path to redeploy capital at above-cost-of-capital returns for 5–10+ years?
  • Management quality: Aligned / Adequate / Extractive. Apply incentive architecture screen before evaluating business quality.
  • Gate 1 verdict: PASS (continue) or FAIL → DISCARD

Gate 2 — The Coordinates: Corporate Life Cycle & Earnings Quality

  • Where is [TICKER] in its corporate life cycle? (Early growth / Mid-growth / Mature / Harvest / Declining)
  • Are reported earnings distorted? Flag: large GAAP-to-non-GAAP gaps, recurring "one-time" charges, heavy intangible amortization from acquisitions, SBC that management excludes from non-GAAP.
  • Adjust ROIC for intangibles: if significant unrecorded intangibles exist (brand, network, data, relationships), note that reported ROIC understates true returns. If large goodwill/acquisition intangibles inflate invested capital, note that reported ROIC may understate returns as amortization runs off.
  • Is ROIC persistently above WACC? If ROIC < WACC, growth destroys value — flag explicitly.
  • Gate 2 verdict: PASS or FAIL → DISCARD

Gate 3 — The Price: Reverse-Engineer Embedded Expectations

  • At the current price, what FCF CAGR or earnings growth rate is required over 10 years at a 9–10% discount rate to justify fair value? State this explicitly.
  • Does that required growth rate represent: the optimistic scenario / base scenario / conservative scenario?
  • Is there a margin of safety? (I.e., does the conservative scenario still support current price?)
  • Gate 3 verdict: PASS (margin of safety present) or FAIL → WAIT

Gate 4 — The Risk: Payoff Asymmetry

  • Is the payoff structurally asymmetric? More upside than downside from here?
  • Are you convex or concave to the primary stressors the business faces? Reference the stressors identified in Section 1.
  • Does the business benefit from volatility and disorder, or does it get hurt by them?
  • Gate 4 verdict: PASS (convex / asymmetric) or FAIL

Gate 5 — Execution: Conviction & Deployment Heuristic

  • Summarize the Quality Score (moat persistence + operating profitability) and Safety Score (earnings floor + balance sheet floor) in qualitative terms.
  • Assign a conviction tier using a simple heuristic appropriate for an uncertain environment:
    • Tier 1 (High conviction): Strong moat, ROIC > WACC, margin of safety, convex payoff, aligned management
    • Tier 2 (Moderate conviction): 2–3 of the above present; 1–2 missing but not disqualifying
    • Tier 3 (Watch / speculative): Framework passes partially; significant uncertainty on key gates
    • Not investable: Gate 1 or Gate 2 failure
  • Note any framework limitations for this specific business (e.g., financial company, pre-profit, commodity cyclical) where the standard gates break.

SECTION 5 — Three Reasons to Sell (Thesis Integrity Check)

Assess the current status of each sell trigger:

  • Leg 1 broken: Loss of management integrity, skill, or alignment
  • Leg 2 broken: Moat eroded by technological disruption or competition
  • Leg 3 broken: Reinvestment runway permanently exhausted

For each: is it broken, showing early signs of strain, or intact?
Is any sell signal currently triggered?


FORMATTING INSTRUCTIONS

  • Lead with a brief key metrics snapshot: price, market cap, revenue, net income, FCF, ROIC, SBC, notable debt figures.
  • Use a clear section header for each of the 5 sections above.
  • Use a summary comparison table at the end only if comparing multiple tickers.
  • Flag any data that required estimation or where confidence is low.
  • Do not produce portfolio recommendations or position sizing unless I explicitly ask.
  • Note if this business type falls outside the framework's intended scope (banks, pre-profit, commodity cyclicals).
