Which is better, KLAC or ON?

On the Buffett-Fit framework, KLA Corporation (KLAC) currently grades higher than ON — 80/100 (A grade) vs 48/100 (D). That said, "better" depends on which framework you trust — KLAC wins on Warren Buffett, Benjamin Graham, Philip Fisher, Peter Lynch, Joel Greenblatt, Charlie Munger, and Terry Smith; ON wins on none. The full pillar breakdown is on this page.

Should I buy KLAC or ON?

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

On the Buffett-style value-investing framework, KLAC currently grades higher — 80/100 vs 48/100, a 32-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 KLAC and ON 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). KLAC currently scores 80/100 (A grade); ON scores 48/100 (D grade). The "Where each wins" section on this page breaks down which pillar each stock dominates.

Which has the stronger moat, KLAC or ON?

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

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 KLAC and ON both Technology stocks?

Yes — both KLA Corporation (KLAC) and ON Semiconductor Corporation (ON) operate in the Technology 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 KLAC vs ON 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.
