What stands out about Sandisk?
- The share price implies 8.4% yearly growth. At $1260.93, SNDK's free cash flow of $72.76 per share would have to grow 8.4% 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 about the same growth as the baseline. Change the assumptions.
- Misses 2 of the 8 value filters. It fails Price/Book < 8 (12.66) and Price/Sales < 7 (9.84); the other 3 pass and 3 were not evaluated. See every filter.

What would Buffett & Lynch say?
Buffett's checklist is built around durable, profitable businesses bought at sensible prices, and SNDK doesn't clear enough of it yet. In its favor: SNDK is currently earning a strong return on shareholders' equity, carries a conservative amount of debt relative to equity, converts sales into profit at healthy margins, 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: SNDK and its five-year average return on equity falls short too, so this isn't just a one-off dip, hasn't grown earnings per share fast enough over five years to impress him, doesn't cover its interest expense as comfortably as he'd want, and is trading above what a conservative discounted-cash-flow estimate says it's worth right now.

Lynch looked for growth stories that weren't overpriced for that growth, and SNDK falls short of his bar. In its favor: SNDK clears his signature PEG-under-1 test: growth at a reasonable price, isn't leaning on debt to fund that growth, isn't asking investors to overpay for that growth, and is backing its growth up with real free cash flow. Where it comes up short: SNDK is growing earnings outside the 10–25% range he considered the sustainable sweet spot.

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.

How much have Sandisk shareholders gained per year?
Not enough clean earnings history to compute this for SNDK yet - a loss year in the window breaks the growth math rather than faking a number through it.
An earnings-based proxy, not a stock-price total return - it doesn't capture multiple expansion/contraction or reinvested dividends. EPS from SNDK's own 10-K filings; dividend yield is the current trailing yield on today's price, from the same weekly fetch as the rest of this site.
What do Sandisk's 10-year financials show?
From SNDK's own 10-K filings (SEC EDGAR): up to the last 4 fiscal years. Press any year's bars for the exact figures.
