PCAR vs RUSHB: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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.

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. PCAR and RUSHB 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 PCAR and RUSHB 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.

PACCAR Inc designs and builds premium heavy-duty and medium-duty trucks under the Kenworth and Peterbilt brands in North America and the DAF brand in Europe, and it sells them across more than 100 countries. Beyond the trucks themselves, the company runs two structurally more profitable businesses: PACCAR Parts, which supplies aftermarket components across the installed fleet, and PACCAR Financial Services, which finances truck purchases for dealers and customers. This parts-and-finance layer generates recurring, higher-margin income that partly cushions the deep swings in new-truck demand.

Rush Enterprises, Inc. (NASDAQ: RUSHA and RUSHB) runs Rush Truck Centers, the largest network of medium- and heavy-duty commercial truck dealerships in North America, with roughly 167 dealership locations plus about 61 leasing locations across 24 U.S. states and Ontario, Canada. It sells new and used trucks from brands including Peterbilt, International, Ford, Hino, Isuzu, Dennis Eagle, and Blue Arc, and, importantly, earns a large and steadier share of profit from aftermarket parts, service, and collision repair, plus truck leasing and rental, financing, and insurance. The aftermarket and service side of the business is the ballast that makes Rush less cyclical than a pure new-truck seller, because trucks on the road still need parts and maintenance even when new-vehicle demand softens.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• PCAR drivers: Freight cycle recovery; Parts and finance annuity.
• RUSHB drivers: Aftermarket parts and service as a cushion; Dealership network consolidation and adjacent businesses.

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: PACCAR's core end market is deeply cyclical, so a prolonged freight recession or a jump in customer financing costs can cut deliveries and earnings quickly, as the soft 2025 showed. For RUSHB, the core risk is cyclicality: new commercial-truck sales rise and fall sharply with freight rates, fleet profitability, interest rates, and the broader industrial economy, and truck volumes softened in early 2026.

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 PCAR if you believe its drivers more; RUSHB 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 PCAR and RUSHB guides.

PCAR. PACCAR earned about $2.5 billion over the trailing twelve months on roughly $27.8 billion of revenue, still near the bottom of the truck cycle after a 2025 in which revenue fell to about $26.2 billion. At about $111 a share the market cap is near $59 billion and the trailing P/E is about 23x, but on analysts' forward EPS of roughly $7.16 the multiple drops to about 16x, so the valuation leans on a recovery in deliveries. Analysts' mean price target is about $133, and the company also pays a variable year-end extra dividend on top of the regular one.

RUSHB. Rush Enterprises earns lower margins on truck sales but steadier, higher-margin income from aftermarket parts, service, and leasing, so revenue mix matters as much as the top line. Revenue has stabilized after a soft 2025, and Q2 2026 net income rose to about $72.8 million. Because RUSHA and RUSHB share identical economics but now trade at very different prices, the same earnings work out to about 26 times trailing for Class B versus about 20 times for Class A, so the class premium is the main valuation question specific to RUSHB.

Headline figures (approximate, October 2026): PCAR shows revenue (ttm) ~$27.8B, revenue growth (latest qtr, yoy) ~0.5%, net income (ttm) ~$2.5B (9% margin), operating margin ~12%; RUSHB shows revenue (ttm) ~$7.24 billion, q2 2026 revenue ~$1.90 billion (down ~1.6% YoY), net income (ttm) ~$265 million (Q2 2026: ~$72.8 million), gross / operating margin ~20% / ~5%.

PCAR and RUSHB 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.
