What stands out about AutoZone?
- The share price implies 24.4% yearly growth. At $3270.70, AZO's free cash flow of $101.13 per share would have to grow 24.4% a year, fading to 2.5% by year 10, for this site's DCF (10% discount rate) to match the price. This site's baseline starts at 8%, so the price asks for more growth than the baseline. Change the assumptions.
- Misses 2 of the 8 value filters. It fails PEG Ratio < 1.5 (3.79) and Price/Book < 8 (880.38); the other 4 pass and 2 were not evaluated. See every filter.
- The margin of safety is falling. It went from -68% on Oct 7 to -89% on Oct 23 across 5 weekly readings. See the trend.
- Weakest against peers: debt / equity. At 37.81 (peer median 0.84) it ranks 20th of 21 among retail stocks this site tracks. See the ranking.
- Balance sheet in the distress zone. Its Altman Z″-Score is 0.03; below 1.1 is the distress zone, 1.1 to 2.6 the grey zone. See the Altman Z″-Score list.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and AZO doesn't clear enough of it yet. In its favor: AZO is currently earning a strong return on shareholders' equity, and has kept that profitability up over five years, not just this year, converts sales into profit at healthy margins, has grown earnings per share at a solid clip over five years, and earns many times its interest expense, so debt service isn't a worry. Where it comes up short: AZO carries more debt relative to equity than he typically tolerates, is trading above what a conservative discounted-cash-flow estimate says it's worth right now, and trades rich relative to owner earnings, the real cash the business could pay out.

Lynch looked for growth stories that weren't overpriced for that growth, and AZO falls short of his bar. In its favor: AZO is growing at the modest, GDP-ish pace typical of a slow grower. Where it comes up short: AZO doesn't pay much of a dividend, which is the main reason to own a slow grower in the first place, carries more debt than he liked to see, even allowing for the extra room a large, stable business gets, is priced too rich for how little growth is actually left in the business, and trades expensive relative to the cash it actually generates.

Quantitative approximations of each investor's documented approach, not endorsed by either investor or their estates - commentary, not this site's actual ranking criteria. Buffett never published a numeric checklist: only 2 of his 8 checks here trace to his own documented concepts ("owner earnings," from his 1986 shareholder letter, and "price is what you pay, value is what you get," his case against fixed P/E/P/B ceilings) - the other 6 (ROE, debt, margins, growth, interest coverage) use commonly-cited thresholds that are not numbers he himself published. The 8 hard filters below (plus the Munger check and Graham margin of safety) are this site's real, mechanical screen and are computed completely independently of the checklists above.
