Buffett Quality · Criteria after Warren Buffett

Looks for the economics of a durable moat: return on equity ≥ 15%, gross margin ≥ 40%, net margin ≥ 15%, debt/equity ≤ 0.5 and multi-year free-cash-flow growth. Financials excluded.

Pass rule: a name qualifies on at least 80% of its evaluable criteria (here, 4 of 5), so the allowance moves with coverage: a name whose fifth criterion is not checked has to clear all four of the rest.

Tenet's independent, mechanical implementation of criteria published in Berkshire Hathaway shareholder letters, quantified by practitioners.

What is the Tenet Score? →

passesfailsborderlineunknown

A name qualifies when it clears at least 4 of the 5 criteria, or the same share of however many of them carry data. A criterion shown as "not checked" leaves the count on both sides, so the bar scales with it rather than buying a spare miss (at least 3 of the 5 must have data).

ROE: Return on equity · Gross margin: Gross profit margin · Net margin: Net profit margin · Debt/equity: Total debt to shareholders' equity (lower is safer) · Growing FCF: Free-cash-flow growth per year, from the oldest to the newest of up to six fiscal years on file

Common questions

What makes a stock a 'Buffett quality' stock?

Durable competitive advantages that show up in the numbers: persistently high returns on equity, fat margins, conservative debt and growing owner cash flows. This screen applies those thresholds mechanically. It captures the quantifiable slice of Buffett's approach, not his judgment.

Does Buffett actually use a screen like this?

No, and we say so plainly. Buffett weighs management, brand and industry structure no screen captures. This list finds companies whose financials clear the thresholds Tenet applies; the qualitative work is still yours.

Which stocks pass today?

275 of 2123 US names (as of 2026-10-01). The free view publishes the top 5 by Tenet Score with their full per-criterion receipts and the rest with Premium, financials excluded, recomputed nightly.

Why is a name on the list when its receipt fails one of the criteria?

Because the bar is a share of the criteria that carry data, not a fixed count: a name qualifies by clearing at least 4 of the 5 criteria when all 5 have data, so a ✕ on its receipt is expected, not an error. A criterion shown as "not checked" leaves the count on both sides, so a name with fewer evaluable criteria has to clear the same share of those, and at least 3 of the 5 must have data.

Every row carries its qualifying math, frozen at run time.
