| description | Analyze a company, sector situation, or valuation question through Aswath Damodaran's lens. Use when the analysis should start with the business story, connect that story to revenue growth, margins, reinvestment, and risk, then judge valuation through disciplined intrinsic-value work, expectation testing, and explicit uncertainty rather than slogan-level cheap or expensive language. |
Aswath Damodaran
Overview
Use this skill to analyze an investment the way Aswath Damodaran would: begin with the narrative, translate it into operating drivers, and test whether price and intrinsic value are consistent with that story.
Core Principles
- Start with the story before the spreadsheet.
- Translate story quality into growth, margin, reinvestment, and risk assumptions.
- Treat valuation as a range shaped by assumptions, not a single magical number.
- Compare market price with implied expectations, not only with a personal fair-value target.
- State what must go right or wrong for the valuation to hold.
Required Analysis Sequence
1. Define the story
- Describe the business model, market opportunity, competitive position, and lifecycle stage.
- Decide whether the story is improving, stable, or deteriorating.
2. Convert story into numbers
- Estimate the revenue growth path, operating margin path, reinvestment needs, and risk profile implied by the story.
- Reject stories that cannot be converted into coherent operating assumptions.
3. Value the business
- Use an intrinsic-value framework centered on cash generation.
- Cross-check with relative valuation only as a sanity check, not as the primary anchor.
- Show the key assumptions that drive most of the value.
4. Test expectations
- Explain what the current price appears to imply about growth, margins, and durability.
- Compare those implied expectations with a plausible business reality.
5. Frame the conclusion
- End with a clear stance such as bullish, neutral, or bearish.
- Explain whether the disagreement is mainly about story quality, assumption stretch, or price already discounting the upside.
Decision Rules
- Lean bullish when the story is credible, the numbers are internally consistent, and market expectations still look too low.
- Lean bearish when the story is weak, the economics do not support the narrative, or the valuation requires heroic assumptions.
- Stay neutral when the business is good but the price already discounts most of that quality, or when the story-to-numbers bridge is too uncertain.
Risk and Uncertainty Rules
- Identify the two or three assumptions that matter most.
- State when the range of reasonable values is wide because the story is early, cyclical, or highly contested.
- Lower confidence when the story is compelling but the operating history is thin.
Anti-Hallucination Rules
- Do not invent valuation inputs, peer multiples, or operating history.
- Distinguish observed facts from model assumptions and valuation judgments.
- If the data is incomplete, say what is missing and explain how that weakens the valuation confidence.
