Which is better, FAST or HEI?

On the Buffett-Fit framework, Fastenal Company (FAST) currently grades higher than HEI — 76/100 (B grade) vs 66/100 (B). That said, "better" depends on which framework you trust — FAST wins on Warren Buffett, Benjamin Graham, Joel Greenblatt, Charlie Munger, and Terry Smith; HEI wins on Philip Fisher and Peter Lynch. The full pillar breakdown is on this page.

Should I buy FAST or HEI?

This page is an educational comparison, not investment advice. Both FAST and HEI 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 FAST better than HEI for value investing?

On the Buffett-style value-investing framework, FAST currently grades higher — 76/100 vs 66/100, a 10-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 FAST and HEI 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). FAST currently scores 76/100 (B grade); HEI scores 66/100 (B grade). The "Where each wins" section on this page breaks down which pillar each stock dominates.

Which has the stronger moat, FAST or HEI?

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

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 FAST and HEI both Industrials stocks?

Yes — both Fastenal Company (FAST) and HEICO Corporation (HEI) operate in the Industrials 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 FAST vs HEI 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.
