calcvi-data

Static data repository for CalcVI 2.0 — Calculadora de Valor Intrínseco App (v2.4.x).

Serves monthly JSON snapshots of:

IBOVESPA stocks — top-discounted BR tickers ranked by intrinsic value (BG & FL formulas)
US stocks — top-discounted US tickers ranked by the same formulas
All stocks — complete catalog (BR + US) with fundamentals and historical multiples

Consumed by the CalcVI app on startup and throughout sessions to pre-populate ranked lists and stock data without requiring live API calls to fundamentals servers.

Update Cadence

Brazil (IBOVESPA): Updated monthly by running npm run publish-top from the CalcVI project. USA: Updated monthly by running npm run publish-us from the CalcVI project.

Intrinsic value is derived from quarterly earnings data (LPA, VPA) and historical median P/L and P/VPA multiples. Fundamentals change at most four times per year (Q1–Q4), so monthly snapshots age gracefully for several weeks.

In the App:

HomeScreen displays atualizadoEm alongside ranked lists so users see data freshness
DetailScreen shows fundamentals from the pre-fetched catalog before falling back to live Yahoo Finance prices
All platforms (Android, iOS, web) read the same JSON endpoints — no platform-specific formatting

Formulas

Both formulas calculate intrinsic value (VI) per share using LPA (earnings) and VPA (book value).

BG — Benjamin Graham (Graham Formula)

VI = √(22.5 × LPA × VPA)

Designed for industrial/tangible-asset companies. Uses a universal constant 22.5 (representing 15× historical earnings multiple and 1.5× book value multiple). Conservative and less sensitive to company-specific multiples.

FL — Felipe Lacerda (Brazilian Value Investing Adaptation)

VI = √(median(P/L) × median(P/VPA) × LPA × VPA)

Designed for intangible-asset companies (tech, SaaS, services). Uses company-specific historical median P/L (price-to-earnings) and P/VPA (price-to-book) multiples from past quarters instead of a universal constant. More adaptable to sector and company characteristics. Better for growth-oriented sectors where BG may undervalue quality assets.
