VALUATION SIGNAL

MARGIN OF SAFETY

Is this stock cheap or expensive relative to what the business has historically generated for owners?

Margin of Safety unavailable — insufficient data for the owner-earnings DCF.

BRINA GAP ↗

Is the market underestimating or overestimating what this business is capable of going forward?

+10.1%

Market Underestimates

💰 How is Margin of Safety calculated? +

Margin of Safety measures how much discount or premium you're paying relative to a stock's intrinsic value. It's Benjamin Graham's core principle: the larger the margin, the lower your downside risk.

Formula: (Intrinsic Value − Current Price) ÷ Intrinsic Value × 100%

How We Calculate Intrinsic Value (DCF Method):

Step 1: Calculate current Owner Earnings (OCF − Maintenance CapEx)

Step 2: Calculate company-specific growth rate using log-linear regression on 16 quarters of Owner Earnings

Step 3: Project 10 years forward using the calculated growth rate

Step 4: Discount each year's cash flow to present value using 10% discount rate

Step 5: Calculate terminal value using 3% perpetual growth rate

Step 6: Sum all discounted cash flows = Intrinsic Value

What The Percentages Mean:

+50% or more

EXCELLENT — Very undervalued

+25% to +50%

GOOD — Attractive discount

0% to +25%

FAIR — Reasonable value

0% to -25%

CAUTION — Slight premium

-25% or worse

POOR — Overvalued

📈 How is Brina Gap calculated? +

Brina Gap measures the difference between the growth a business can fundamentally sustain and the growth the market is already pricing in.

Formula: Fundamental Growth Rate − Market-Implied Growth Rate

The Two Components:

Fundamental Growth Rate = ROIC × Reinvestment Rate

What the business can sustainably grow at based on how much it reinvests and what return it earns on that capital. Grounded in historical financials.

Market-Implied Growth Rate = Reverse DCF

The growth rate the current Enterprise Value implicitly assumes. Calculated by back-solving a 10-year DCF model (10% WACC, 3% terminal growth) until the present value of projected cash flows equals EV.

What The Gap Means:

Gap > +5% Market Underestimates — potential upside

+2% to +5% Slight Underestimate

-2% to +2% Fairly Priced — market consensus matches fundamentals

-5% to -2% Slight Overestimate

Gap < -5% Market Overestimates — price embeds optimism fundamentals don't support

A positive gap (market underestimates) combined with a positive Margin of Safety is the strongest combined signal — the business is both cheap historically and forward economics are stronger than the price suggests.
