CLF vs STLD: 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. CLF and STLD 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 CLF and STLD 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.

Cleveland-Cliffs is North America's largest flat-rolled steel producer and the largest supplier of automotive-grade steel in the United States. It is vertically integrated, owning iron ore mines and pellet operations and converting raw materials and scrap through primary steelmaking into downstream finishing, stamping, tooling, and tubing. It makes money by selling steel to automakers, service centers, infrastructure, appliance, and other industrial customers; roughly a third of output goes to the automotive sector, and Q1 2026 steelmaking revenue included ~$1.4 billion (~29%) of direct automotive sales. The company employs roughly ~25,000 people across mining, steel, and manufacturing operations in the U.S. and Canada.

Steel Dynamics is a Fort Wayne, Indiana based steel producer and metals recycler, one of the largest in the United States. It makes steel almost entirely through electric arc furnaces (EAFs), which melt scrap rather than iron ore, a lower-cost and lower-emission model than traditional blast furnaces. The company operates across three legs: steel operations (flat-rolled, long products, and specialty shapes), metals recycling through its OmniSource network that feeds scrap into the mills, and steel fabrication (joists and decking). In 2025 it added a fourth leg by starting up a $2.7 billion aluminum flat-rolled mill in Columbus, Mississippi, aimed at the beverage-can and automotive markets.

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

• CLF drivers: U.S.-only footprint plus tariff tailwind; Integration and scale.
• STLD drivers: Low-cost EAF steel operations; Aluminum expansion into can and auto sheet.

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: Cleveland-Cliffs is one of the more cyclical and leveraged names in the steel sector. For STLD, the biggest risk is cyclicality: steel and aluminum prices swing with construction, autos, and the broader economy, and a downturn can compress the price-to-scrap spread that drives profits.

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 CLF if you believe its drivers more; STLD 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 CLF and STLD guides.

CLF. Cliffs is a deeply cyclical steelmaker, so trailing earnings reflect a trough rather than a steady run rate, and a trailing P/E is not meaningful while the company posts losses. On forward estimates (about $0.95 of 2027 EPS) the stock trades near 13 times earnings and about 0.37 times sales, and the mean analyst target of about $12.60 sits close to the $12.46 close, with a consensus rating of hold. Investors typically watch EV/EBITDA, leverage, and whether the Q3 2026 report on October 19 delivers the guided swing to profit.

STLD. Steel Dynamics generated about $18.2 billion of net sales and $1.2 billion of net income in 2025, and the 2026 rebound has lifted trailing earnings to ~$1.61 billion. At roughly ~$35 billion of market value the shares trade around 22 times trailing earnings but only about 11 to 12 times 2027 consensus, a gap that only holds if steel spreads stay firm. Third-quarter results arrive October 19, 2026 with consensus near ~$5.40 per share.

Headline figures (approximate, October 2026): CLF shows revenue (ttm) ~$19.2 billion, revenue growth (q2 2026, yoy) ~6%, q2 2026 net loss ~$145 million (EPS -$0.20 vs -$0.22 est.), net income (ttm) ~-$866 million; STLD shows revenue (ttm) ~$20.5B, up ~33% year over year in Q2 2026, margins ~14.7% gross, ~11.5% operating, ~7.8% net, net income (ttm) ~$1.61B, trailing EPS of ~$11.03, q2 2026 results ~$6.09B revenue, ~$534M net income, EPS ~$3.69 vs ~$3.67 expected.

CLF and STLD 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.
