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`	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%)

Holdings File

Default reads from

~/.openclaw/workspace/holdings.md

Data Source

Yahoo Finance API (yfinance)
