CIG-C currently scores 44/100 (D grade); SBS scores 57/100 (C grade). The "Where each wins" section on this page breaks down which pillar each stock dominates.

Which has the stronger moat, CIG-C or SBS?

Moat strength is one of the five pillars in the Buffett-Fit score on this page. CIG-C and SBS are each scored on ROIC sustainability, gross-margin durability, and qualitative signals like brand strength, switching costs, network effects, and regulatory barriers. The pillar breakdown on this page shows the moat sub-score side-by-side so you can see which one has the more durable competitive advantage.

Which is more undervalued, CIG-C or SBS?

Valuation is one of the five Buffett-Fit pillars on this page. Both stocks are scored on owner-earnings yield, price-to-intrinsic-value vs the underlying compounding rate, and the margin of safety relative to a conservative DCF. The valuation sub-score in the table below tells you which one currently trades at a more attractive price relative to its underlying business quality.

Are CIG-C and SBS both Utilities stocks?

Yes — both Companhia Energética de Minas Gerais (CIG-C) and Companhia de Saneamento Básico do Estado de São Paulo - SABESP (SBS) operate in the Utilities sector. That makes this a direct sector-peer comparison, which is the apples-to-apples way to use the Buffett-Fit framework: the score weighs each stock against its sector's specific quality and valuation benchmarks (sector-relative bonus), so the cross-stock comparison isn't distorted by inter-sector base-rate differences.

Is this CIG-C vs SBS comparison investment advice?

No. This page is an educational pattern-match against documented public frameworks (Buffett, Graham, Fisher, Lynch, Greenblatt, Munger, Smith), not personalised investment advice. The scores reflect how closely each stock matches each framework's documented criteria — they are not buy/hold/sell recommendations. Always do your own research and consult a licensed financial adviser for personalised advice.
