Is BRK.A better than SPY for value investing?

On the Buffett-style value-investing framework, SPY currently grades higher — 50/100 vs 28/100, a 22-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 BRK.A and SPY on Warren Buffett's framework?

BRK.A currently scores 28/100 (F grade); SPY scores 50/100 (C grade). The "Where each wins" section on this page breaks down which pillar each stock dominates.

Which has the stronger moat, BRK.A or SPY?

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

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.

Can you compare BRK.A (Financials) and SPY (Financial Services) directly?

BRK.A is a Financials stock and SPY is in Financial Services, so this is a cross-sector comparison. The Buffett-Fit scoring on this page applies sector-relative bonuses to each stock against its own sector benchmarks, so the cross-sector comparison is still meaningful — but for the cleanest like-for-like, sector peers usually compare better than cross-sector pairs.

Is this BRK.A vs SPY 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.
