ODFL vs SAIA: Which Is the Better Buy in 2026?

Last updated September 2026

Short answer

ODFL is the larger of the two ($38.89B market cap): the incumbent the market prices for continued execution (28.16x forward earnings, beta 1.18). SAIA is the smaller challenger ($8.82B), cheaper on forward earnings (23.43x): 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.

ODFL vs SAIA: the tie-breaker metrics

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.

MetricODFLSAIAWhat it tells you
Market cap$38.89B$8.82BSize. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E28.1623.43Valuation 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/E35.9632.01Valuation 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.
Beta1.182.14Volatility 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 range48% of range34% of rangeWhere 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 / book8.533.24How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price.

Reading it: SAIA 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 ODFL and SAIA 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. ODFL and SAIA 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 ODFL and SAIA 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 Old Dominion Freight Line (ODFL) do?

Old Dominion Freight Line is a non-union less-than-truckload (LTL) motor carrier that moves palletized freight for thousands of business customers across a company-owned network of roughly 260 service centers spanning the continental US. LTL means consolidating multiple shippers' partial loads onto one trailer, a dense, service-intensive business where Old Dominion has built a reputation for best-in-class on-time delivery (about 99%) and a very low cargo claims ratio (under 0.1%). That service premium lets it charge higher yields (revenue per hundredweight) and consistently run the lowest operating ratio in the industry, meaning it keeps more of every revenue dollar as profit than peers.

What does Saia (SAIA) do?

Saia, Inc. is a national less-than-truckload carrier that hauls pallet-sized shipments for many customers on shared trucks across a network of more than 200 terminals, competing in the same LTL niche as Old Dominion. The company has spent aggressively since 2022, opening dozens of new terminals (including facilities picked up after rival Yellow collapsed in 2023) and investing over $2 billion in real estate and technology to expand its geographic footprint from a regional Southern base toward true national coverage.

ODFL vs SAIA: 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.

  • ODFL drivers: Market-share gains from service leadership; Yield and pricing discipline.
  • SAIA drivers: National network expansion; Volume re-acceleration and margin leverage.

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: Freight demand is cyclical and tied to industrial production and goods consumption, so a prolonged soft patch pressures volumes, as seen in the roughly 7.7% Q1 2026 tonnage decline. For SAIA, saia's earnings are highly cyclical and tied to industrial production, retail freight, and the broader economy, so a prolonged freight recession pressures volumes and pricing at once.

ODFL or SAIA: 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 ODFL if you believe its drivers more; SAIA 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 ODFL and SAIA guides.

ODFL vs SAIA: the full fundamentals

ODFL. ODFL posted Q1 2026 revenue of about $1.33 billion, down roughly 2.9% year over year, with EPS of about $1.14 that beat estimates on firm pricing despite lower volumes. Trailing-twelve-month revenue is around $5.5 billion against roughly $1.0 billion of net income. The premium multiple (P/E near 40) reflects the market's willingness to pay up for the strongest margins and service record in LTL.

SAIA. Q1 2026 revenue set a record near $806M, up about 2.4% year over year, though margins were pressured by immature terminals and soft demand. The stock's roughly high-30s price-to-earnings multiple sits well above the broad market, reflecting expectations for continued expansion and eventual margin recovery. Figures are approximate and shift with each quarterly report and stock-price move; the Q2 2026 results were due around July 30, 2026.

Headline figures (approximate, JULY 2026): ODFL shows revenue (ttm) ~$5.5B, net income (ttm) ~$1.0B, market cap ~$42B, q1 2026 diluted eps ~$1.14; SAIA shows revenue (ttm) ~$3.2B, net income (ttm) ~$320M, diluted eps (ttm) ~$11, market cap ~$11B.

FAQ

What is the difference between ODFL and SAIA?

+

Old Dominion Freight Line is a non-union less-than-truckload (LTL) motor carrier that moves palletized freight for thousands of business customers across a company-owned network of roughly 260 service centers spanning the continental US. Saia, Inc. 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 ODFL or SAIA the better stock?

+

Neither is universally better. ODFL is the larger incumbent; SAIA is the smaller challenger and looks cheaper 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, ODFL or SAIA?

+

On forward P/E (as of September 2026), ODFL trades at 28.16x and SAIA at 23.43x, so SAIA 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 ODFL and SAIA?

+

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 ODFL vs SAIA?

+

ODFL: Freight demand is cyclical and tied to industrial production and goods consumption, so a prolonged soft patch pressures volumes, as seen in the roughly 7.7% Q1 2026 tonnage decline. The premium valuation (a P/E near 40) leaves little room for disappointment and can compress sharply if growth stalls. Fuel costs, wage inflation, and aggressive expansion by peers such as Saia, XPO, Estes, and FedEx Freight can erode pricing and share. A weaker operating ratio during downturns amplifies earnings swings, and any loss of the service edge that justifies premium pricing would undercut the core thesis. SAIA: Saia's earnings are highly cyclical and tied to industrial production, retail freight, and the broader economy, so a prolonged freight recession pressures volumes and pricing at once. The heavy terminal-expansion program raises costs and capital spending ahead of the revenue it is meant to generate, keeping the operating ratio elevated and dragging on near-term margins. The stock trades at a premium price-to-earnings multiple, which amplifies downside if growth or margin recovery disappoints. Competition from larger and better-capitalized rivals such as Old Dominion is intense, and fuel prices, driver costs, and labor availability all add volatility. Weather and seasonal demand swings can materially move any single quarter.
