Output Metrics
- PEG Ratio = Forward P/E ÷ EPS Growth Rate

- 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%)
