What stands out about Best Buy Co?
- The share price implies shrinking cash flow. At $99.83, BBY's free cash flow of $10.01 per share would have to shrink 5.1% a year at first, then recover to 2.5% growth by year 10, for this site's DCF (10% discount rate) to match the price. This site's baseline starts at 8% growth, so the price asks for less growth than the baseline. Change the assumptions.
- Misses 1 of the 8 value filters. It fails Market Cap > $25B ($20.5B); the other 5 pass and 2 were not evaluated. See every filter.
- Strongest against peers: free-cash-flow yield. At 10.0% (peer median 4.4%) it ranks 1st of 21 among retail stocks this site tracks. See the ranking.
- Weakest against peers: revenue growth. At 1.4% (peer median 7.7%) it ranks 21st of 21 among retail stocks this site tracks. See the ranking.
- Short interest is elevated. 7.6% of the float is sold short, 4.4 days to cover, above this site's 5% flag. See the figures.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and BBY doesn't clear enough of it yet. In its favor: BBY is currently earning a strong return on shareholders' equity, and has kept that profitability up over five years, not just this year, carries a conservative amount of debt relative to equity, earns many times its interest expense, so debt service isn't a worry, is trading below what a conservative discounted-cash-flow estimate says it's worth - his own "price is what you pay, value is what you get" test, not a fixed multiple ceiling, and trades at a reasonable multiple of owner earnings, his own term for the real cash a business could pay out. Where it comes up short: BBY runs thinner pretax margins than he'd like to see, and hasn't grown earnings per share fast enough over five years to impress him.
- ROE (TTM) > 11% ✓
- ROE (5yr avg) > 11% ✓
- Debt/Equity < 0.5 ✓
- Pretax margin > 15% ✕
- EPS growth (5yr) > 7% ✕
- Interest coverage > 5x ✓
- Trading below intrinsic value (DCF) ✓
- Price vs. owner earnings < 25x ✓
- Bonus: returning capital via buybacks FY2026
Lynch looked for growth stories that weren't overpriced for that growth, and BBY falls short of his bar. In its favor: BBY clears an even tighter PEG-under-1 bar he'd want for a stock growing this fast, isn't leaning on debt to fund that growth, isn't asking too much even by a fast grower's usual richer multiple, and is generating real cash to back up a fast grower's higher price tag. Where it comes up short: BBY is growing earnings outside the 20-50% band he considered sustainable for a fast grower - either not fast enough to earn the label, or a pace he'd flag as unlikely to hold up.
- PEG < 1 (stricter for fast growers) ✓
- EPS growth 20%-50% ✕
- Debt/Equity < 0.5 ✓
- P/E < 40 ✓
- Price/FCF < 40 ✓
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.
