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

Same yardstick, side by side (as of September 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 acquisitions.

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 reported about $28.4 billion in revenue and $2.4 billion of net income in 2025, an off-cycle year, with adjusted diluted earnings of roughly $5.01 per share. At around $123 per share the stock carries a market cap near $65 billion and a P/E in the mid-20s, a premium for an industrial that reflects its quality, aftermarket annuity, and capital returns. The company pays a modest regular dividend supplemented by a variable year-end extra dividend tied to annual results.

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. In the first quarter of 2026, total revenue fell to about $1.68 billion as new-truck volumes softened, yet net income and EPS rose year over year, showing that the parts-and-service and leasing businesses cushioned the cyclical dip in vehicle sales. Because RUSHA and RUSHB share identical economics, valuation multiples such as the price-to-earnings ratio (roughly the low twenties in mid-2026) apply to the same underlying earnings for both share classes.

Headline figures (approximate, JULY 2026): PCAR shows revenue (2025) ~$28.4B, net income (2025) ~$2.4B, q1 2026 revenue ~$6.8B, market cap ~$65B; RUSHB shows revenue (ttm) ~$7.8 billion, q1 2026 revenue ~$1.68 billion (down from ~$1.85B a year earlier), q1 2026 net income ~$61.5 million, q1 2026 diluted eps ~$0.77 (up from ~$0.73).

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.
