Stock Valuation
⚠️ Data Verification — Do This Before Any Analysis
Before running any analysis, always retrieve the latest market data for the ticker:
- Fetch current price — use web search or ask the user for the live price, 52-week range, and market cap. Never assume a price from training data.
- Confirm key figures — recent earnings, revenue, key ratios (P/E, P/S, etc.) as applicable to this skill.
- State your data source — note where the numbers came from (e.g., "Google Finance, June 19 2026") at the top of the output.
- Flag stale data explicitly — if live data is unavailable, display this warning before proceeding:
⚠️ Live data unavailable. The following analysis uses training-data estimates which may be significantly out of date. Verify all prices and metrics before making any decisions.
Never silently substitute training-data estimates for current prices. When in doubt, ask the user to paste the latest quote.
Derive a rigorous intrinsic value estimate using multiple independent valuation methodologies, then triangulate to a single probability-weighted target price. Never rely on a single method — cross-validation across DCF, comparable company analysis (CCA), EV/EBITDA, and residual income models builds conviction and exposes assumption fragility.
Overview
Valuation is an art grounded in financial science. Each method has strengths and weaknesses depending on the business type, stage of maturity, and data availability. This skill applies four to five valuation methods, then reconciles them into a football field chart to show the implied value range. Wherever there is consensus across methods, conviction is high. Where methods diverge significantly, that gap tells you something important about market expectations.

Margin of Safety Framework
Margin of Safety = (Intrinsic Value − Market Price) / Intrinsic Value × 100%

Investor Type Minimums:
Deep Value: 25–35% margin of safety required
GARP: 10–20% margin of safety
Growth: 0–10% (or slight premium for high-quality growth)
Momentum: Not applicable

Deep DCF Modeling
This section provides the full step-by-step DCF construction methodology for analysts who need a more rigorous, first-principles build. Use this when the quick DCF in Method 1 above requires deeper documentation, when running a standalone DCF, or when preparing material for an investment committee.
Revenue Growth — Multi-Anchor Approach
Use multiple anchors to triangulate a defensible growth assumption:
- Segment approach: Project each revenue segment separately when possible (e.g., services vs. hardware, cloud vs. on-prem, international vs. domestic)
- Historical growth analysis: 3yr, 5yr, and 10yr revenue CAGR as a baseline anchor
- Analyst consensus estimates: Use sell-side consensus for years 1–3 as a cross-check
- Management guidance: Forward revenue guidance and long-term targets from earnings calls and investor days
- Industry growth rate: Use as a ceiling anchor (a company cannot sustainably grow faster than its industry forever)
- Growth tapering: Apply higher growth in years 1–5, decelerating in years 6–10 toward the terminal growth rate
FCF Margin Construction
Project future FCF margins based on operating leverage and business model dynamics:
- Historical FCF margin trend (expanding, stable, or compressing — identify the driver)
- Operating leverage potential: As revenue scales, what fixed costs are being leveraged? (R&D, G&A, sales infrastructure)
- Capex intensity (% of revenue): Is capex increasing (scaling infrastructure) or decreasing (mature asset base)?
- Working capital changes: Is the company a working capital consumer or generator? (subscription businesses often generate WC)
- Normalize for one-time items: Strip out litigation settlements, asset sale gains, restructuring charges
- SBC adjustment: Subtract SBC from reported operating cash flow to get true economic FCF
Terminal Value — Two Methods
Terminal value represents all cash flows beyond the 10-year explicit forecast period:
- Terminal growth rate (g): Typically 2–3% (anchored to nominal GDP growth). Never set g > WACC — this implies infinite value
- Gordon Growth Model (preferred):
TV = FCF₁₀ × (1 + g) / (WACC − g) - Exit Multiple Method (alternative):
Use industry-appropriate EV/FCF multiples from comparable mature companiesTV = FCFₙ × (EV / FCF exit multiple) - Terminal value as % of Enterprise Value: If TV > 80% of total EV, the model is highly sensitive to terminal assumptions. Flag this explicitly and widen the sensitivity range

Low risk (utility) 6–8% Regulated utilities, large cap staples
Medium risk 8–11% Large cap tech, established growth
High risk 11–15% Small cap, emerging market, cyclical
Very high risk 15–20%+ Early-stage, distressed, pre-revenue
Three-Scenario Model — Full Detail
Always present three scenarios with explicit assumption differences and probability-weighted output:
Three-Scenario DCF Framework
Scenario Probability Revenue CAGR (Y1-5) FCF Margin (Y5) WACC Terminal g
Bull 20% [higher growth] [higher margin] [lower] [2.5%]
Base 60% [consensus growth] [stable margin] [base] [2.0%]
Bear 20% [lower growth] [compressed] [higher] [1.5%]
Scenario Narratives:
Bull Case: Favorable macro, market share gains, operating leverage, margin expansion
Base Case: Historical trend continuation, modest improvement in line with guidance
Bear Case: Competitive pressure, margin compression, macro headwinds, execution risk
Intrinsic Value Output:
Bull Case IV: $[value]
Base Case IV: $[value]
Bear Case IV: $[value]
Probability-Weighted IV = (20% × Bull IV) + (60% × Base IV) + (20% × Bear IV) = $[value]
The probability-weighted IV is the primary output used for investment decision-making.

[*] Shaded cell = Base Case assumption
Interpretation guide:
- If the entire table shows a margin of safety vs. current price → high confidence in undervaluation
- If only a few cells show margin of safety → valuation depends critically on specific assumptions
- If no cells show margin of safety → stock is expensive under all reasonable DCF scenarios
Common DCF Pitfalls
- Garbage in, garbage out: Extrapolating recent high-growth rates too far into the future. Be conservative, especially in years 6–10.
- Terminal value dominance: If TV > 70% of enterprise value, the model is more speculation than analysis. Stress-test terminal assumptions aggressively.
- WACC too low: Using a WACC below the risk-free rate, or ignoring size/liquidity premiums for smaller companies, artificially inflates intrinsic value.
- Ignoring cyclicality: Using peak FCF margins as the base for a cyclical business. Always normalize FCF through a full business cycle.
- Ignoring stock-based compensation: SBC is a real, dilutive cost. Subtract it from operating cash flow when calculating true economic FCF.
- Single scenario thinking: Presenting only a base case. Always run Bull, Base, and Bear scenarios with explicit assumption differences.
- Hidden working capital and capex changes: Rapidly growing companies often consume significant working capital. Ensure this drag is reflected in FCF projections, not hidden in operating cash flow.
- Currency and geographic mix: For international businesses, project by geography and apply appropriate discount rates by region.
When DCF Is (and Isn't) the Right Tool
When DCF is most reliable:
- Stable, mature businesses with predictable, consistent FCF
- Asset-light businesses with high FCF conversion (e.g., software, consumer brands)
- Companies with 10+ years of FCF generation history
- Businesses where future cash flows are reasonably bounded (regulated utilities, subscription SaaS)
When DCF is less reliable (use relative valuation instead):
- Early-stage growth companies with no positive FCF yet — value lies in future optionality
- Highly cyclical businesses where normalizing FCF requires significant judgment
- Financial companies (banks, insurance, REITs) — use Price/Book, Price/Earnings, or dividend discount models instead
- Companies with lumpy or unpredictable capex cycles
- Turnaround situations where the path to profitability is uncertain
