If you searched "is Tesla a good Buffett stock" or "Tesla stock analysis 2026", here's the answer in one paragraph: Tesla currently scores 0 of 7 on our framework consensus. Not one of the seven legendary value-investing frameworks - Buffett, Graham, Fisher, Lynch, Greenblatt, Munger, Smith - flags TSLA as Strong Fit. Six say Weak Fit. Lynch is the only Partial Fit, and only on the growth pillar.
This post walks through which specific number kills each framework's verdict, then asks the more interesting question: what would Tesla need to do to flip to a Strong Fit?

The 7-of-7 verdict at a glance
| Framework | Verdict | Killer metric | The exact number |
|---|
| Buffett | Weak Fit | Owner-earnings yield | 0.4% (need ≥ 5%) |
| Graham | Weak Fit | P/E ratio | 326 (defensive max: 15) |
| Fisher | Weak Fit | Gross margin | 17.6% (need ≥ 50%) |
| Lynch | Partial Fit | PEG ratio | ~4.5 (need ≤ 1.0) |
| Greenblatt | Weak Fit | Earnings yield rank | bottom 5% of universe |
| Munger | Weak Fit | ROIC | 3.1% (need ≥ 18% sustained) |
| Smith | Weak Fit | FCF / Net Income | 28% (need ≥ 95%) |
Zero strong fits. One partial. Six weak.
The pattern is the most informative thing about Tesla as a value-investing candidate: it isn't that some frameworks like it and some don't. It's that all of them reject it on the price side and most reject it on the quality side too.
Why each framework rejects TSLA, in detail
Buffett: owner-earnings yield 0.4%
The Buffett scorer computes owner-earnings as Free Cash Flow minus maintenance capex, divided by market cap. Tesla's reported FCF is real but small relative to the ~$1T market cap. Owner-earnings yield comes in at 0.4% - meaning you'd take 250 years to recoup your purchase price at current cash generation if growth froze.
Buffett's published floor is 5% absolute owner-earnings yield for stable businesses (and higher for cyclicals). 0.4% fails by an order of magnitude.
What would flip this: FCF would need to grow ~12x, OR the market cap would need to fall by ~90%, OR both meet halfway. Realistic over a 10-year window? Possible, if Tesla becomes profitable on autonomy + energy as bulls argue. Possible to under-write today on the current numbers? Buffett says no.
Graham: P/E 326
This is the simplest of the seven verdicts. Graham's defensive criteria max out at P/E 15. The enterprising-investor screen accepts P/E up to 20-25 if EPS growth justifies it. Tesla's P/E of 326 fails any version of Graham by a 15-22x margin.
Graham also fails Tesla on P/B (~12, max 1.5), current ratio (1.7, min 2.0), and 5-year profitability stability. Not one defensive criterion passes.
What would flip this: ¯\(ツ)/¯. Graham's framework was designed in 1949 and is the strictest of the seven on absolute valuation. Tesla's price would need a 95% reset for Graham to even partial-fit.
Fisher: gross margin 17.6%
Fisher's framework rewards businesses with high gross margins as a proxy for pricing power and R&D capacity. Tesla's gross margin sits around 17-18% (with significant quarter-to-quarter variability based on EV mix and FSD revenue recognition).
Fisher's threshold is 50% gross margin sustained for 5+ years. Tesla has never been close. The auto-manufacturing component of the business has a structural ceiling around 25-30% gross margin (Toyota peaks at ~22%, Mercedes around 24%). To pass Fisher, Tesla would need its high-margin businesses (Energy + FSD + Software) to dominate the mix to the point that the company-wide gross margin reaches 50%.
What would flip this: Tesla becomes a software company first and a car company second, with software / autonomy / energy reaching ~70% of gross profit. Bulls argue this is the path. The 2026 reality is the car side dominates.
Lynch: PEG ~4.5
This is where the framework gets interesting. Lynch's "growth at a reasonable price" framework would love Tesla's growth (EPS growth has been triple-digit in some years) IF the P/E ratio was anywhere near reasonable.
PEG = P/E divided by EPS growth rate. Tesla's P/E of 326 divided by even an optimistic 70% forward EPS growth rate gives PEG = 4.6. Lynch's framework rejects anything above PEG 1.0 as not GARP.
The Lynch verdict is Partial Fit rather than Weak Fit because Lynch's framework gives partial credit for the underlying growth rate even when valuation fails. Lynch in his own books was explicit: "I'd own a great growth company at a fair price; I'd never own one at this price."
What would flip this: EPS growth accelerates to triple digits OR P/E compresses to under 50. Lynch is the most-flippable of the seven.
Greenblatt: bottom 5% on earnings yield
Magic Formula ranks the universe on two metrics - earnings yield (1/PE adjusted for cash and debt) and ROIC. It then picks the stocks with the best combined rank.
Tesla's earnings yield rank is in the bottom 5% of the 3,700-stock universe (most cyclical commodity producers have higher earnings yields by definition because their P/E is depressed at the cycle bottom).
Tesla's ROIC rank, however, is around the middle of the universe (3% is not great but isn't catastrophic). Combined Magic Formula rank: roughly 2,800 out of 3,500. Bottom quintile.
What would flip this: ROIC needs to rise sharply (autonomy economics) OR earnings yield needs to normalise (multiple compression). Either reset would also flip Buffett.
Munger: ROIC 3.1%
Munger's framework is more permissive on valuation than Buffett's (P/E up to 30 OK if quality justifies), but it's stricter on quality. The hard floor is ROIC ≥ 18% sustained for 5+ years.
Tesla's ROIC peaked at ~28% in 2022, then fell to ~3% in 2024 as EV margins compressed and R&D spend ramped on FSD + Optimus. The 5-year average is around 9-10%, which fails Munger's 18% floor.
What would flip this: ROIC recovers to 20%+ sustained. Plausible if FSD becomes profitable; uncertain timing.
Smith: FCF / Net Income 28%
Terry Smith's Fundsmith framework is the strictest on cash-conversion quality. The criterion is FCF / Net Income ≥ 95% sustained, meaning the company turns its reported profit into actual cash.
Tesla's FCF / Net Income ratio has been wildly variable, from negative (when capex outpaces earnings) to 30-40% in good years. The trailing-twelve-month ratio is around 28%.
Smith also has hard exclusions for cyclical / commodity / capital-intensive businesses, and Tesla's auto-manufacturing side trips both the cyclical (automotive) and capital-intensive (factories) filters.
What would flip this: Smith's framework would need a structural carve-out for autonomy economics that the framework simply doesn't have. Realistically, Smith never owns Tesla in his current published framework.
The bull case
If Tesla bulls are right, the screen is wrong. Specifically:
- Autonomy economics: FSD at scale generates software-business margins on a hardware-business installed base. Gross margin company-wide would rise toward 50%+ over a decade. Fisher and Smith would unblock.
- Energy business: Tesla Energy is roughly 6% of revenue at 24% gross margin and growing 70%+ YoY. If it scales to 30%+ of revenue, the company-wide mix shifts.
- Operating leverage on Optimus: humanoid robots at scale represent a TAM larger than autos. Speculative, but not impossible.
None of these are in the current numbers. The screen scores what is, not what might be. Every value-investing framework explicitly does this on purpose - Graham warned about projection in 1949, Buffett re-stated it in every letter since 1985.
The bear case
If Tesla bears are right, the price was always the entire bear case. Specifically:
- Auto margin compression continues: Chinese EV competition + legacy OEMs catching up. Margin floor lower than the bulls assume.
- FSD economics never materialise: regulatory + technical risk. Five years of "next year" without commercial robotaxi deployment.
- Optimus is a long-dated option, not a near-term P&L item: discounting back to present value, the contribution to current owner-earnings is small.
The bear case is just "the price is too high relative to current cash generation". That's what 7 of 7 frameworks effectively say.
What this is good for
Tesla is the cleanest stress-test of value-investing dogma in the entire S&P 500. If you believe in the future you can make a great case, but the current numbers force every value framework to reject the price. Honest investors should be able to hold both thoughts at once:
- The business may well be incredible in 2035
- The price today is incompatible with every published value framework
invest-like surfaces both halves on the same page. The TSLA Boardroom is the single most-requested debate from new users - open it, watch the four investors argue, and decide for yourself.
