Actionable insights — 5 copper stocks: which is best?

The repeatable process behind the ranking: not which copper miner Lukacs prefers, but how he compares a sector's majors side by side — commodity exposure, cycle-distorted profitability, gross vs net debt, a quality-first ranking and a crash-triggered entry — so the grid can be rerun on any commodity group.

How to read this page: each insight is a method — a supply-response test, an exposure breakdown, a profitability sanity check, a leverage screen, a ranking rule, an entry trigger — with the boxed line showing how Lukacs applied it to the five copper majors and a "watch for" list for re-running it. Timestamps deep-link into the video.

02:54 1. Test whether high prices can cure themselves — the wheat-vs-copper check

The repeatable method
  1. Ask how fast supply can respond to a price rise: next season (crops) or a decade (mines needing discovery, development, permits)?
  2. Check the discovery pipeline: exploration spend vs number and size of major discoveries, and how much found resource is stuck in feasibility.
  3. Map where the remaining resource sits — geographic concentration adds permitting and political risk that slows supply further.
Here: wheat supply responds next year; copper "you need to find it… develop it… get permits" (03:12); only six major discoveries (~9 Mt) in 2020–25, ~500 Mt in feasibility (03:40); Latin America ~55% of major discovered copper (04:12).

04:39 2. Decompose each "copper stock" by actual commodity exposure before comparing

The repeatable method
  1. Break each candidate's EBITDA into commodities (and non-mining arms like trading).
  2. Use the mix to explain relative stock performance — a lagging name may just be the other commodity's weakness.
  3. Note partial substitutes (aluminium for copper) as diversification rather than dilution.
Here: FCX ~pure copper, BHP ~54%, RIO ~36% + ~20% aluminium, GLEN ~30% + trading and coal, VALE ~23% / ~80% iron ore (05:00) — Vale's lag since 2024 is weak iron ore vs strong copper (02:01).
Watch for

07:02 3. Strip boom years out of multi-year profitability averages

The repeatable method
  1. Compute a seven-year average ROI/ROE for each name, then locate which years drive it.
  2. If a single commodity boom inflates the average, discount it — "the past is not indicative necessarily of the future."
  3. Re-think forward profitability from the commodity each company will be most exposed to next, plus logistics (distance to the main buyer).
Here: BHP, VALE, RIO lead the seven-year averages only because 2021–22 were exceptional iron-ore years (07:39); Australian producers sit close to Asian demand while Vale ships bulky ore from South America (08:13).
Watch for

08:56 4. Screen leverage with a simple rule — then adjust for businesses that carry inventory-financing debt

The repeatable method
  1. Apply a rule of thumb: debt-to-equity ≤50% and interest coverage ≥5×.
  2. For an outlier, ask why: trading/marketing businesses borrow against liquid inventories and receivables, so use net debt, not gross.
  3. Confirm with the credit rating and note how far each sits above the BBB− investment-grade cutoff.
Here: GLEN fails the gross screen but gross debt ~$45bn vs net ~$10bn — "also a safe balance sheet player" (09:44); BHP/Rio single-A, Glencore/Vale BBB+/BBB, FCX BBB− "right above the speculative grade cutoff" (10:15).
Watch for

10:36 5. Rank on quality first; use valuation to decide when, not which

The repeatable method
  1. Score each name on asset quality (tier-one), through-cycle profitability, credit rating, exposure to the thesis commodity and shareholder-return policy.
  2. Rank by that score — not by cheapness; the cheapest name often carries the structural problems (legacy liabilities, the wrong commodity).
  3. Only then check valuation (forward FCF yield, scenario DCF) to decide whether today is an entry.
Here: "I used to be more valuation focused but I realized that I have to just focus much more on quality. So… BHP is my number one" (10:36); VALE is cheapest but carries Samarco/Brumadinho liabilities and iron-ore dependence (13:34).
Watch for

01:00 6. Match a business model to your macro regime — volatility beneficiaries in a fragmented world

The repeatable method
  1. State your macro regime view (here: a more fragmented, geopolitically volatile world).
  2. Look in past shocks (war outbreaks) for which names spiked most relative to peers — that reveals built-in volatility exposure.
  3. Favour the business model that earns from the regime itself (trading/marketing), not just from the commodity price.
Here: GLEN spiked hardest in 2022 (Ukraine) and 2026 (Iran) because "higher war and geopolitical volatility results in higher earnings" (01:26); "the trader plus commodity player like Glencore could benefit" (12:32).
Watch for

11:24 7. When the story is priced in, pre-rank the list and wait for the crash

The repeatable method
  1. If a widely known thesis has every name at fair value or a premium, don't compromise on price — "optimism is priced in."
  2. Keep the ranked list ready; treat broad sell-offs and recessions (when cyclicals fall hardest) as the entry.
  3. Size up aggressively on the top-ranked name when it comes ("load the truck").
Here: "none of these looks cheap" (05:46); for BHP "if there is a recession… this could crash. I could maybe load the truck" (11:24); "I want them to basically crash and then I can pick my favorites" (16:09).
