AN vs SAH: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
AN is the larger of the two ($7.11B market cap): the incumbent the market prices for continued execution (8.71x forward earnings, beta 0.75). SAH is the smaller challenger ($2.90B), actually pricier on forward earnings (11.86x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
AN vs SAH: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | AN | SAH | What it tells you |
|---|---|---|---|
| Market cap | $7.11B | $2.90B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 8.71 | 11.86 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 9.84 | 14.58 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.75 | 0.90 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 60% of range | 63% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 3.19 | 2.88 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: AN is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how AN and SAH affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AN and SAH share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AN and SAH exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does AutoNation (AN) do?
AutoNation operates a nationwide network of franchised new-vehicle dealerships across three segments (Domestic brands like GM and Ford, Import brands like Toyota and Honda, and Premium Luxury brands like Mercedes-Benz and BMW), alongside standalone AutoNation USA used-vehicle stores, collision centers, and an in-house lending arm, AutoNation Finance. The company sells new and used vehicles, but its most profitable work is aftersales (parts, service, and repair) and finance and insurance products, which together make up roughly 22% of revenue yet contribute around 75% of gross profit.
What does Sonic Automotive (SAH) do?
Sonic Automotive (NYSE: SAH) is a US automotive retailer that runs franchised new-and-used vehicle dealerships (many of them luxury and import brands concentrated in large metro markets, with Texas and California alone around half of revenue) alongside EchoPark, its standalone pre-owned-vehicle brand. The bulk of each dealership's gross profit comes not from the low-margin new-car sale itself but from higher-margin parts and service, finance and insurance (F&I), and used-vehicle reconditioning, which makes the model more resilient than a pure car-sales business.
AN vs SAH: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- AN drivers: Aftersales and higher-margin mix; Used vehicles and AutoNation USA.
- SAH drivers: Parts, service, and F&I as the profit engine; EchoPark turning profitable.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Auto retailing is cyclical and sensitive to interest rates, vehicle affordability, and consumer confidence, all of which can pressure unit volumes and gross profit per vehicle. For SAH, auto retail is cyclical and sensitive to interest rates, vehicle affordability, and consumer confidence, so a downturn can hit both unit sales and F&I income at once.
AN or SAH: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AN if you believe its drivers more; SAH if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AN and SAH guides.
AN vs SAH: the full fundamentals
AN. AutoNation trades at a low earnings multiple relative to the broad market, which is typical for cyclical, capital-intensive auto dealers. Gross margin improved modestly to about 18.5% in Q1 2026, and adjusted free cash flow was roughly $256 million, funding the sizable buyback program.
SAH. Sonic trades at a mid-20s trailing P/E on a market cap near $2.6 billion, richer than several dealership peers that sit closer to 8-12x, partly reflecting a lower earnings base and the EchoPark turnaround optionality. Q1 2026 adjusted EPS of about $1.62 beat consensus and grew roughly 9 percent, while GAAP net income fell on a tough prior-year comparison that had included cyber-insurance proceeds. The valuation should be read against a heavily levered, cyclical business that returns most free cash flow through buybacks and dividends.
Headline figures (approximate, July 2026): AN shows revenue (ttm) ~$27.6B, q1 2026 revenue ~$6.6B, q1 2026 adjusted eps ~$4.69, market cap ~$8B; SAH shows revenue (fy2025) ~$15.2B, revenue (q1 2026) ~$3.7B, adjusted eps (q1 2026) ~$1.62, market cap ~$2.6B.
The bottom line: AN vs SAH
AN and SAH are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AN and SAH exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between AN and SAH?
+
AutoNation operates a nationwide network of franchised new-vehicle dealerships across three segments (Domestic brands like GM and Ford, Import brands like Toyota and Honda, and Premium Luxury brands like Mercedes-Benz and BMW), alongside standalone AutoNation USA used-vehicle stores, collision centers, and an in-house lending arm, AutoNation Finance. Sonic Automotive (NYSE: SAH) is a US automotive retailer that runs franchised new-and-used vehicle dealerships (many of them luxury and import brands concentrated in large metro markets, with Texas and California alone around half of revenue) alongside EchoPark, its standalone pre-owned-vehicle brand. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is AN or SAH the better stock?
+
Neither is universally better. AN is the larger incumbent; SAH is the smaller challenger and looks pricier on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, AN or SAH?
+
On forward P/E (as of August 2026), AN trades at 8.71x and SAH at 11.86x, so AN is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both AN and SAH?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of AN vs SAH?
+
AN: Auto retailing is cyclical and sensitive to interest rates, vehicle affordability, and consumer confidence, all of which can pressure unit volumes and gross profit per vehicle. New-vehicle pricing and margins have been normalizing lower from post-pandemic highs, and same-store new-unit sales have declined. The finance arm adds credit and funding risk if loan losses rise in a weaker economy. The business is capital-intensive, carries meaningful debt and floorplan financing, and depends on manufacturer relationships and inventory allocations. Longer term, the shift to electric vehicles and any changes to the franchised-dealer model could reshape the industry. SAH: Auto retail is cyclical and sensitive to interest rates, vehicle affordability, and consumer confidence, so a downturn can hit both unit sales and F&I income at once. New-vehicle gross profit per unit is still normalizing from post-pandemic highs, which can pressure earnings even as revenue grows. The company carries meaningful debt, including floor-plan financing whose cost rises with interest rates, and EchoPark's profitability, while improved, has a history of volatility. A dual-class share structure concentrates voting control with insiders, limiting outside-shareholder influence, and manufacturer franchise agreements plus a secular shift toward EVs and direct-to-consumer sales models add structural uncertainty.
