ECO vs ZIM: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
ZIM is the larger of the two ($3.04B market cap): the incumbent the market prices for continued execution (-11.25x forward earnings, beta 1.12). ECO is the smaller challenger ($2.36B), priced similarly on forward earnings (10.89x): 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.
ECO vs ZIM: 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 | ECO | ZIM | What it tells you |
|---|---|---|---|
| Market cap | $2.36B | $3.04B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 10.89 | -11.25 | 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 | 10.60 | 30.72 | 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. |
| Price vs 52-week range | 99% of range | 73% 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 | 3.25 | 0.79 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how ECO and ZIM 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. ECO and ZIM 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 ECO and ZIM 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 Okeanis Eco Tankers Corp (ECO) do?
Okeanis Eco Tankers Corp. owns and operates a fleet of 16 modern, scrubber-fitted crude oil tankers, split evenly between eight VLCCs (very large crude carriers) and eight Suezmax vessels. Incorporated in the Marshall Islands and run out of Neo Faliro, Greece, the company hauls crude oil around the world on the spot market and through time charters, and it trades on both the Oslo Stock Exchange (OET) and the NYSE (ECO). Its "eco" branding refers to the fuel-efficient, emissions-reducing design of a relatively young fleet, which the company argues wins premium rates and lower operating costs versus older tonnage.
What does ZIM Integrated Shipping Services Ltd (ZIM) do?
ZIM Integrated Shipping Services Ltd. is a container shipping company founded in 1945 and headquartered in Haifa, Israel. It operates as a global liner carrier, moving containerized cargo across more than 90 countries and over 300 ports, serving in excess of 30,000 customers. As of the end of 2025 it ran a fleet of roughly 128 vessels (about 115 container ships plus around 13 vehicle carriers) across a network of some 56 weekly lines, and after a multi-year fleet renewal program roughly 40 percent of its capacity is now LNG-powered, one of the more modern and fuel-efficient profiles among liner operators.
ECO vs ZIM: 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.
- ECO drivers: Tanker rate cycle and rerouting; Modern, scrubber-fitted fleet.
- ZIM drivers: The Hapag-Lloyd cash merger; Modern, fuel-efficient fleet.
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: Crude tanker shipping is one of the most cyclical corners of the market, and ECO's earnings and dividend can fall dramatically when day rates decline, as the early-2026 rate slump illustrated. For ZIM, the largest single risk is deal risk: Israeli government bodies including the Ministry of Economy and the Shipping and Ports Authority have publicly opposed the Hapag-Lloyd merger on national-shipping and supply-chain grounds, and if the transaction is blocked or renegotiated the stock could reprice sharply toward its standalone value.
ECO or ZIM: 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 ECO if you believe its drivers more; ZIM 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 ECO and ZIM guides.
ECO vs ZIM: the full fundamentals
ECO. As of July 2026 ECO traded around $53 per share, valuing the company near $2.2B on roughly 39M shares. Trailing figures reflect a strong tanker market, with FY2025 revenue of about $392M and profit of about $123M, while the higher TTM numbers capture the late-2025 rate peak. The single-digit P/E and high dividend yield are typical of shipping stocks priced for the cycle to eventually cool rather than compound.
ZIM. ZIM swung from record pandemic-era profits to a much softer 2025 and a Q1 2026 net loss as container freight rates normalized. With a pending $35.00-per-share cash acquisition on the table, the market price tends to track the merger spread more than traditional earnings multiples, so standard valuation ratios are less informative than the probability and timing of the deal closing.
Headline figures (approximate, JULY 2026): ECO shows market cap ~$2.2B, revenue (ttm) ~$482M, net income (ttm) ~$199M, diluted eps (ttm) ~$5.83; ZIM shows revenue (fy2025) ~$6.9B, net income (fy2025) ~$479M, q1 2026 revenue ~$1.40B, q1 2026 net loss ~$86M (EPS ~-$0.71).
The bottom line: ECO vs ZIM
ECO and ZIM 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 ECO and ZIM exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between ECO and ZIM?
+
Okeanis Eco Tankers Corp. ZIM Integrated Shipping Services Ltd. 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 ECO or ZIM the better stock?
+
Neither is universally better. ZIM is the larger incumbent; ECO 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, ECO or ZIM?
+
On forward P/E (as of August 2026), ECO trades at 10.89x and ZIM at -11.25x, so ZIM 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 ECO and ZIM?
+
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 ECO vs ZIM?
+
ECO: Crude tanker shipping is one of the most cyclical corners of the market, and ECO's earnings and dividend can fall dramatically when day rates decline, as the early-2026 rate slump illustrated. A record surge in VLCC and Suezmax newbuild orders raises the risk of oversupply and weaker rates once those ships deliver. The company is exposed to oil demand, OPEC+ production choices, sanctions and geopolitical shifts that redraw trade routes, and volatile bunker fuel costs. As a Marshall Islands-incorporated foreign private issuer with a concentrated fleet and near-100% payout, it carries limited financial cushion, currency and interest-rate exposure on vessel debt, and single-incident operational risk from any accident or vessel detention. ZIM: The largest single risk is deal risk: Israeli government bodies including the Ministry of Economy and the Shipping and Ports Authority have publicly opposed the Hapag-Lloyd merger on national-shipping and supply-chain grounds, and if the transaction is blocked or renegotiated the stock could reprice sharply toward its standalone value. Beyond the deal, ZIM faces the structural cyclicality of container shipping, where freight rates, fuel costs, and new vessel supply can swing results dramatically. It carries geopolitical exposure through its Israeli base and Middle East trade lanes, and its dividend is variable and was suspended for Q1 2026 after the quarterly net loss. A prolonged rate downturn would pressure both earnings and cash returns if the company were to remain independent.
