Valuation Calculator is a fast command-line stock valuation tool that delivers instant market metrics and multi-method valuations. Use it to compute PEG, forward/trailing P/E, implied EPS growth, EV/EBITDA, Rule of 40, and full DCF models for single tickers, portfolios, or major indices. Key features include concise commands (e.g., value, value peg, value ev, value dcf), DCF parameter controls (--wacc, --growth, --terminal), and an --auto mode that computes WACC via a CAPM-based estimate using live 10-year Treasury yields and beta. It reads portfolio positions from a default holdings.md, pulls market data via yfinance, and supports index snapshots (SPY, QQQ, DIA). Ideal for rapid investment research, earnings prep, portfolio-level valuation checks, and sensitivity analysis with reproducible, scriptable outputs for workflow automation.

Fast stock valuation calculator with instant market valuation metrics.
Commands
| Command | Description |
|---|---|
value <ticker> | Full valuation for a single stock |
value peg <ticker> | PEG + Forward/Trailing P/E + Implied Growth |
value ev <ticker> | EV/EBITDA + Rule of 40 |
value dcf <ticker> | DCF valuation (default parameters) |
value dcf <ticker> --auto | DCF with auto-calculated WACC (CAPM model) |
value dcf <ticker> --wacc=0.10 --growth=0.15 --terminal=0.03 | Custom DCF parameters |
value | All holdings valuation (reads from holdings.md) |
value --index | Three major indices (SPY, QQQ, DIA) |
Output Metrics
- PEG Ratio = Forward P/E ÷ EPS Growth Rate
- Forward P/E = Based on next 12 months expected earnings
- Trailing P/E = Based on past 12 months actual earnings
- Implied EPS Growth = (Trailing P/E ÷ Forward P/E - 1) × 100%
- EV/EBITDA = Enterprise Value ÷ EBITDA
- Rule of 40 = Revenue Growth % + Profit Margin %
- DCF = Discounted Cash Flow valuation
DCF Parameters
| Parameter | Description | Default |
|---|---|---|
--auto | Auto-calculate WACC using CAPM model | - |
--wacc=N | Weighted Average Cost of Capital | 10% |
--growth=N | Future growth rate | 5% |
--terminal=N | Terminal growth rate | 2.5% |
Auto WACC (CAPM Model)
WACC = Rf + β × (Rm - Rf)
- Rf = 10-year Treasury yield (auto-fetched from Yahoo Finance)
- β = Stock beta (from Yahoo Finance)
- Rm - Rf = Market risk premium (5.5%)

Default reads from ~/.openclaw/workspace/holdings.md
Data Source
