## What it does

The skill lays out the standard valuation toolkit: discounted cash flow, the Gordon growth model for terminal value, WACC, CAPM, dividend discount models, residual income, peer multiples (P/E, EV/EBITDA, P/S, P/B) and sum-of-the-parts. Formulas sit in one table, followed by two worked examples — a two-stage DCF and a peer-median P/E estimate.

A pitfalls section covers what usually goes wrong. Terminal value often drives 60–80% of the result, so those assumptions deserve a look before anything else. It also flags false precision, trailing multiples on fast-growing companies, and the circular reference where WACC depends on a market cap the WACC itself produced.

The skill installs into Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode. You supply the company figures yourself; there is no price data bundled in.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill quantitative-valuation -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/quantitative-valuation/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/quantitative-valuation/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill quantitative-valuation -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/quantitative-valuation/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill quantitative-valuation -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/quantitative-valuation/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install JoelLewis/finance_skills quantitative-valuation
```

2. **Manually: put the files in place**
- File: `.github/skills/quantitative-valuation/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill quantitative-valuation -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/JoelLewis/finance_skills --path plugins/wealth-management/skills/quantitative-valuation
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/quantitative-valuation/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add JoelLewis/finance_skills --skill quantitative-valuation -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/JoelLewis/finance_skills/tree/HEAD/plugins/wealth-management/skills/quantitative-valuation/SKILL.md

## When to use it
- run a two-stage DCF to get enterprise value
- price a share off the peer-median P/E
- split the discount rate into cost of equity and after-tax debt
- test how far the result moves when WACC and growth shift
- value a negative-free-cash-flow company via residual income

## Example prompts
- Run a DCF with FCF of $100M, 15% growth for 5 years, WACC 10% and terminal growth of 3%
- Estimate fair value from the peer median P/E, EPS $5.00
- Build a sensitivity table across WACC and terminal growth

description: "Estimate intrinsic value of stocks and companies using DCF, dividend discount models, comparable multiples, and residual income. Use when the user asks about discounted cash flow, DCF models, WACC, terminal value, dividend discount models, comparable multiples, or sum-of-the-parts valuation. Also trigger when users mention 'what is this stock worth', 'fair value estimate', 'Gordon growth model', 'free cash flow valuation', 'cost of equity', 'sensitivity analysis', 'exit multiple', or ask whether a stock is overvalued or undervalued."

# Quantitative Valuation

## Core Concepts

### Discounted Cash Flow (DCF)
The DCF model values a company as the present value of its future free cash flows plus a terminal value:

V = Σ FCF_t / (1 + WACC)^t + TV / (1 + WACC)^n

where FCF_t is the free cash flow in year t, WACC is the weighted average cost of capital, and TV is the terminal value at the end of the explicit forecast period.

### Terminal Value — Gordon Growth Model
Estimates the value of all cash flows beyond the explicit forecast period assuming perpetual growth:

TV = FCF_n × (1 + g) / (WACC - g)

where g is the long-term sustainable growth rate (typically near nominal GDP growth, 2-4%).

### Terminal Value — Exit Multiple Method
Estimates terminal value by applying a market multiple to the final-year financial metric:

TV = EBITDA_n × EV/EBITDA multiple

The exit multiple is typically based on current peer trading multiples or long-run sector averages.

### Weighted Average Cost of Capital (WACC)
Blends the cost of equity and after-tax cost of debt weighted by their market-value proportions:

WACC = w_e × r_e + w_d × r_d × (1 - τ)

where w_e and w_d are equity and debt weights, r_e and r_d are their respective costs, and τ is the marginal tax rate.

### Cost of Equity — CAPM
The Capital Asset Pricing Model estimates the required return on equity:

r_e = R_f + β × (R_m - R_f)

where R_f is the risk-free rate, β is the stock's sensitivity to market returns, and (R_m - R_f) is the equity risk premium.

### Dividend Discount Model (DDM)
Values a stock as the present value of its future dividends. The Gordon Growth (single-stage) form:

P = D_1 / (r - g)

where D_1 is the next-period dividend, r is the required return, and g is the constant dividend growth rate.

### Multi-Stage DDM
Accommodates companies transitioning through growth phases:
- **Stage 1 (High growth):** Dividends grow at g_1 for n years
- **Stage 2 (Transition):** Growth declines linearly from g_1 to g_3
- **Stage 3 (Stable):** Dividends grow at g_3 in perpetuity (valued via Gordon Growth)
