What grade does DUOL get on the Buffett framework?

Duolingo, Inc. (DUOL) currently grades C on the Buffett-Fit framework with a composite score of 53/100. The grade ladder is A+ (85-100), A (70-84), B (55-69), C (40-54), D (0-39). Each pillar - moat, durability, management, financial health, valuation - contributes to the composite.

How accurate is the Buffett-Fit framework on DUOL?

The Buffett-Fit framework is a documented pattern-match, not a forecast. The published 5-year backtest on invest-like.com/track-record shows that stocks scoring in the 7/7 consensus tier (the auto-selected best-of-7 tier) returned a median +73.8% above the S&P 500 over a rolling 5-year window (n=47, with 85% of the cohort posting positive 5y returns). DUOL's individual outcome will depend on its own business trajectory, which the score cannot predict.

Should I buy DUOL based on the Buffett-Fit score?

No verdict on invest-like.com is investment advice. The Buffett-Fit score grades how closely Duolingo, Inc. matches Warren Buffett's documented framework - it does NOT account for your personal circumstances, risk tolerance, tax situation, or time horizon. Use the score as one input among many, and always consult a licensed financial adviser before making any investment decision.

Is Duolingo, Inc. (DUOL) a good Buffett stock?

Based on the Buffett-Fit framework, Duolingo, Inc. (DUOL) currently scores 53/100 - a C grade and a partial fit against Warren Buffett's documented criteria. The five pillars (economic moat, earnings durability, management quality, financial health, valuation) drive the composite. The full reasoning behind every pillar is below. Educational only, not investment advice.

Five pillars at a glance. Duolingo, Inc.'s Buffett-Fit score weighs ROIC sustainability (currently 0.1%), gross-margin durability (0.7%), net-debt-to-EBITDA (-5.90x), free-cash-flow conversion (0.89x net income), and the owner-earnings yield (7.5%). Each pillar is scored 0-100 against sector-relative benchmarks.

Where DUOL passes the test. A Buffett-style holding needs durable returns, conservative debt, owner-friendly management, and a price below intrinsic value. The full pillar breakdown on /buffett/duol/ shows where Duolingo, Inc. clears each bar - and where it doesn't. The current composite score (53/100, C) reflects the weighted average across all five pillars.

What the score does NOT say. A high Buffett-Fit grade is a pattern-match against documented criteria, not a forecast. A stock graded A+ today can underperform if its underlying business deteriorates faster than the score updates. A D-graded stock can outperform if it's a value trap that recovers. The score weighs current fundamentals against a documented framework - that's all it claims to do.

How invest-like measures this

The Buffett-Fit framework on invest-like grades any public stock A+ to D on a 0-100 scale across five weighted pillars: economic moat (durable competitive advantage), earnings durability (consistent profitability), management quality (capital allocation), financial health (conservative balance sheet), and valuation (margin of safety).

Each pillar is scored on the same 0-100 sub-scale using the rubric Warren Buffett has documented across 50+ years of Berkshire Hathaway shareholder letters. The overall grade is the weighted average. Educational only - pattern-match against documented public criteria, not personalised investment advice.
