Stock Valuation Lab

Model a stock with several transparent valuation methods, then change the assumptions yourself. Enter a ticker to prefill supported Grizzly Bulls financial data, or use the calculator entirely with your own inputs.
Enter a U.S.-listed ticker. The calculator only prefills fields that clear the existing Grizzly Bulls stock-data rules.

TransDigm Group INC (TDG)

Canonical Grizzly Bulls stock data prefills the fields below where a supported value is available. Forward growth, discount rates, terminal growth, and margin of safety remain your assumptions.

The reference price may be a source-scoped IEX completed-session close rather than a consolidated U.S. market close. Missing values stay missing instead of being inferred from nearby financial statement fields.

Inputs and assumptions

For ticker prefills, this is TTM operating cash flow minus capital expenditures.
Used by reverse DCF to solve for the growth rate implied by the entered market value.
Used only to compare the modeled value with the entered or source-backed market price.

DCF assumptions

Applied during the explicit forecast period.
Must remain below the discount rate.

Earnings and book inputs

Prefilled from latest supported annual diluted EPS for period ended 2025-09-30.
Used only by the growth-adjusted earnings heuristic.

What is driving the FCF DCF?

Add positive free cash flow and shares, a valid discount rate, a terminal growth rate below the discount rate, and a forecast period from 1 to 30 years.

DCF sensitivity

This table moves the explicit FCF growth rate and discount rate around your current assumptions. It keeps the terminal growth rate and forecast length unchanged.

Sensitivity analysis becomes available when the FCF DCF inputs are valid.

FCF DCF and reverse DCF

The FCF model starts with operating cash flow minus capital expenditures, grows it through the explicit forecast period, discounts each year, and applies a perpetual-growth terminal value. It is a simple equity-style model and does not add a separate enterprise-value or net-debt bridge. The reverse DCF uses the same structure but solves for the explicit growth rate that makes the model equal the entered market capitalization.

Terminal value = final forecast FCF × (1 + terminal growth) ÷ (discount rate - terminal growth)

Earnings DCF

The earnings model applies the same discounted-growth structure directly to positive EPS. Ticker lookup does not synthesize trailing EPS from consolidated net income when common-equity attribution is unresolved.

Growth-adjusted earnings

This is a Peter Lynch-style heuristic, not a discounted-cash-flow model. It sets a reference P/E equal to the entered earnings growth rate plus dividend yield, then multiplies that reference multiple by EPS.

Modeled value = EPS × (earnings growth % + dividend yield %)

Graham Number

The Graham Number combines positive earnings per share and positive book value per share into a conservative screening reference. It is not designed for every industry or capital structure.

Graham Number = √(22.5 × EPS × book value per share)
Modeling limits

These calculations are assumption-driven research tools, not price targets or investment recommendations. Small changes in growth, discount rates, terminal growth, capital intensity, or normalized earnings can materially change the output. Source-backed ticker inputs describe retained financial and market observations; the forward assumptions remain hypothetical.

For company-specific context, use the linked Grizzly Bulls stock page alongside the model rather than treating one formula as a complete investment thesis.
