Which is better, GFI or RIO?

On the Buffett-Fit framework, Gold Fields Limited (GFI) currently grades higher than RIO — 72/100 (B grade) vs 47/100 (D). That said, "better" depends on which framework you trust — GFI wins on Warren Buffett, Benjamin Graham, Philip Fisher, Peter Lynch, Joel Greenblatt, Charlie Munger, and Terry Smith; RIO wins on none. The full pillar breakdown is on this page.

Should I buy GFI or RIO?

This page is an educational comparison, not investment advice. Both GFI and RIO are graded against the same Buffett 5-pillar framework (moat, earnings durability, management quality, financial health, valuation) plus six other documented investor frameworks. Read the side-by-side breakdown to see which one matches the criteria you care about most — and always do your own research before making any investment decision.

Is GFI better than RIO for value investing?

On the Buffett-style value-investing framework, GFI currently grades higher — 72/100 vs 47/100, a 25-point gap. The gap is driven by which pillars each stock passes; the table on this page shows moat, durability, management, financial health, and valuation side-by-side.

What's the difference between GFI and RIO on Warren Buffett's framework?

Both stocks are evaluated on the same five pillars: economic moat (durable competitive advantage), earnings durability (consistent profitability), management quality (capital allocation), financial health (conservative balance sheet), and valuation (margin of safety). GFI currently scores 72/100 (B grade); RIO scores 47/100 (D grade). The "Where each wins" section on this page breaks down which pillar each stock dominates.

Which has the stronger moat, GFI or RIO?

Moat strength is one of the five pillars in the Buffett-Fit score on this page. GFI and RIO 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, GFI or RIO?

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 GFI and RIO both Basic Materials stocks?

Yes — both Gold Fields Limited (GFI) and Rio Tinto Group (RIO) operate in the Basic Materials 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 GFI vs RIO 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.
