Both lines start at 200 in the same week, so the distance between them is the whole story: the industry line is an equal-weighted index of its 4 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member rebased to 100 at the start and the industry taking the median — so a price line pulling away from flat bars is a re-rating, not earnings. A bar turns red when that figure is lower than the quarter before. Rules are fixed and applied identically everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover any point to read both values and the gap. This is a description of what the numbers did, not advice.

Is Aluminum outperforming S&P 500?

The central tension: current leadership is concentrated, so durability matters more than rank.
Start with scale. Then earnings trajectory. Then business quality. Only after those three agree should price leadership carry much weight.

4-Factor Sector Score
An additive sector-relative research score. The four displayed point contributions always equal the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or stale evidence is absorbed inside the affected factor, never applied as a hidden adjustment.
Growth & earnings · 35%Capital efficiency · 25%Valuation · 20%Relative strength · 20%
Constellium SE has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 79% evidence confidence.
Missing observations are not scored as bad. Their missing weight lowers confidence and pulls the final score toward neutral. PEG is guarded: positive earnings, positive 5–60% three-year EPS growth, and a positive P/E are required.

Revenue Scale & Growth Durability
Constellium SE has the highest Revenue among the 4 Aluminum companies compared here, at $8,931 million. Century Aluminum Company is next at $2,543 million. The same company also holds the highest Revenue growth, at 20.1%. 2 of 4 companies report a comparable reading, the latest through Mar 2026. Its Revenue series carries 19 reported observations across the 20-quarter window.
What the numbers say: Constellium SE is the scale leader at $8,931 million, 251.2% ahead of Century Aluminum Company. Constellium SE's growth is 20.1% from a $8,931 million base, with 19 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.
LeaderConstellium SE · $8,931 million
Gap251.2% versus #2 · Century Aluminum Company
Persistence5/8 recent comparable periods
Coverage2/4 companies · 76 observations
Investor read: Constellium SE is the scale benchmark; Constellium SE is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.
This conclusion weakens if: Constellium SE's growth falls below Constellium SE's for two consecutive comparable reports while operating margin also compresses.
Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

Capacity Spending & Returns On It
Alcoa Corporation has the highest CAPEX among the 4 Aluminum companies compared here, at $186 million. Century Aluminum Company is next at $75 million. Century Aluminum Company has the highest CAPEX intensity at 11.6%, so level and change sit with different companies. 4 of 4 companies report a comparable reading, the latest through Jun 2026.
What the numbers say: Alcoa Corporation reports $186 million of CAPEX; Century Aluminum Company has the highest covered intensity at 11.6%. Coverage is only 4 of 4 companies and 78 reported observations, so this is partial evidence—not a complete sector rank.
LeaderAlcoa Corporation · $186 million
Gap148% versus #2 · Century Aluminum Company
Persistence8/8 recent comparable periods
Coverage4/4 companies · 78 observations
Investor read: Use the CAPEX rank as a diligence queue. Verify commissioning, utilization, cash conversion and post-investment ROCE before treating spend as value creation.
This conclusion weakens if: CAPEX rises without higher utilization, operating cash flow or incremental returns.
CAPEX is cash spent on property, plant, equipment and other reported capital assets. CAPEX intensity divides that spend by revenue; high intensity is a reinvestment signal, not proof that the reinvestment will earn attractive returns.

Annual capital allocation · 5-year view
4/4 capacity base · 4/4 OCF · 4/4 CAPEX · 4/4 FCF
Capacity base is net fixed assets plus capital work in progress, straight off the reported balance sheet. It is not cash spent, so it answers a narrower question than CAPEX — but it is reported for companies whose cash-flow CAPEX is not published, which is why it leads here. Missing years remain blank; annual values are never relabelled as quarters.

Debt Load & Balance-Sheet Headroom
Century Aluminum Company has the lowest Gross debt among the 4 Aluminum companies compared here, at $546 million. Kaiser Aluminum Corporation is next at $1,060 million. The same company also holds the lowest Net debt, at $302 million. 4 of 4 companies report a comparable reading, the latest through Mar 2026.
What the numbers say: Century Aluminum Company has the clearest covered balance-sheet capacity with $302 million and gross debt of $546 million. Absolute debt alone does not identify the strongest balance sheet because company scale differs; net debt and debt-to-equity carry more information.
LeaderCentury Aluminum Company · $546 million
Gap48.5% versus #2 · Kaiser Aluminum Corporation
Persistence0/8 recent comparable periods
Coverage4/4 companies · 78 observations
Investor read: Prioritize net-cash capacity and leverage relative to operating scale, not the smallest absolute rupee debt.
This conclusion weakens if: Net debt rises faster than revenue and profit for two consecutive reported periods.
Gross debt shows contractual borrowings. Net debt subtracts reported cash; a negative value means net cash. Lower debt can create capacity, but should be read against the scale and capital intensity of the business.

Return On Capital Employed
Century Aluminum Company has the highest ROCE among the 4 Aluminum companies compared here, at 20.7%. Constellium SE is next at 8.5%. The same company also holds the highest ROCE change, at +17.7 percentage points. 4 of 4 companies report a comparable reading, the latest through Mar 2026. Its ROCE series carries 19 reported observations across the 20-quarter window.
What the numbers say: Century Aluminum Company leads ROCE at 20.7%, 12.2 percentage points above Constellium SE. Century Aluminum Company has the strongest latest improvement at +17.7 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.
LeaderCentury Aluminum Company · 20.7%
Gap143.5% versus #2 · Constellium SE
Persistence6/8 recent comparable periods
Coverage4/4 companies · 78 observations
Investor read: Century Aluminum Company sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.
This conclusion weakens if: The next two comparable reports reverse the current roce change signal.
ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Valuation Against Growth & Quality
Constellium SE has the lowest Guarded PEG among the 4 Aluminum companies compared here, at 1.94×. The same company also holds the lowest P/E, at 7.95×. 1 of 4 companies report a comparable reading, the latest through Mar 2026. PEG asks what price is being paid for growth; P/E keeps that answer anchored to the actual earnings multiple.
What the numbers say: Constellium SE has the lowest comparable Guarded PEG at 1.94×. Only 1 of 4 companies pass the guard, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.
LeaderConstellium SE · 1.94×
GapNot enough peers
Persistence0/8 recent comparable periods
Coverage1/4 companies · 5 observations
Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.
This conclusion weakens if: The next two comparable reports reverse the current p/e signal.
PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data sources reconciled. A missing PEG is more honest than a low-base fiction.

Before the conclusion · check the blind spots
What can make this comparison misleading?
This Aluminum comparison names 5 specific ways its own evidence can mislead, all listed below. All 4 companies here report on comparable dates, so no rank carries a stale marker. 3 of the 8 ranked sections have fewer than three usable current readings. A high growth rate can still be a low-base artefact.
Keep these limits visible
- A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
- A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
- The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
- An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
- Thin comparisons: Revenue, Net profit, Valuation have fewer than three usable current readings.
10 · the complete set
Which companies are included?
All 4 companies in the canonical Aluminum membership are listed below, largest market value first — nothing is silently dropped, even where a company reports too little to rank. The charts above default to a selective view; this register is the complete set, with each company's own latest reporting date beside it.
AHEAD means the company is beating the index by 5% or more over three months. LAGGING, FUNDAMENTALS UP means it is 20% or more behind over a year while its trailing twelve-month earnings grew 20% or more. Both rules are fixed and applied the same way in every sector.

Evidence and freshness
How was this comparison built?
This comparison is built from the reported filings of 4 Aluminum companies, normalized to a common $ scale and a shared quarter axis of up to 20 quarters each. Fundamentals run through Jun 2026 and market data through 2026-07-28. A second data feed fills gaps only after identity and scale reconciliation, and missing observations are never interpolated.

Questions investors ask · short, speakable answers
Aluminum company comparison FAQs
These 17 answers restate the Aluminum comparison above in question form. Every one is computed from the same 4 companies and the same reported filings as the rankings and charts, current through Jun 2026. Price and relative-strength answers run through 2026-07-28. Nothing here is estimated, and none of it is a recommendation.
Which Aluminum company is the biggest?
Constellium SE is the largest, with trailing-twelve-month revenue of $8,931 million, ahead of Century Aluminum Company at $2,543 million. That covers 2 of 4 companies with comparable reporting through Mar 2026.
Which Aluminum company is growing fastest?
Constellium SE has the fastest revenue growth at 20.1% year on year, across 2 of 4 comparable companies. Fast growth off a small base is not the same as proven scale — check whether the rate holds across several quarters on the chart above before treating it as a trend.
Which Aluminum company has the best profit margins?
Century Aluminum Company has the highest operating margin at 57.6%, from 4 of 4 comparable companies. Century Aluminum Company shows the biggest recent improvement, at +50.8 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.
Which Aluminum company makes the most profit?
Constellium SE earns the most, at $433 million of trailing-twelve-month net profit, from 2 of 4 comparable companies. Century Aluminum Company has the fastest profit growth at 100%, though growth off a small or recovering profit base overstates how much has actually changed.
Which Aluminum company earns the highest return on capital?
Century Aluminum Company leads on return on capital employed at 20.7%, across 4 of 4 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.
Which Aluminum stock is the cheapest?
On guarded PEG — where a LOWER number is cheaper — Constellium SE screens cheapest at 1.94×. Only 1 of 4 companies pass the comparability guard, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.
Which Aluminum company has the strongest balance sheet?
Century Aluminum Company carries the lowest comparable gross debt at $546 million, from 4 of 4 companies. Absolute rupee debt alone does not settle it, because company scale differs — net debt and debt-to-equity in the chart above carry more information, and a very low-debt balance sheet can also mean under-investment.
Which Aluminum company is investing most in new capacity?
Alcoa Corporation reports the largest capital spending at $186 million, across 4 of 4 companies. Spending consumes cash before it earns anything, so treat the ranking as a diligence queue: check commissioning, utilisation and the return earned on the completed assets before reading spend as value creation.
Is the Aluminum sector beating the market?
Aluminum has outperformed S&P 500 by 75.4% over the last 52 weeks and 19.7% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 2 of 4 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.
Which Aluminum stock has the strongest price momentum?
Kaiser Aluminum Corporation has the strongest relative strength against S&P 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.
Which Aluminum company scores highest for research priority?
Constellium SE scores 67.5 out of 100 with 79% evidence confidence, from 31.5 points on growth and earnings, 7.2 on capital efficiency, 8.8 on valuation and 20 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.
How many Aluminum companies does this comparison cover, and over what period?
It compares 4 listed companies over up to 20 reported quarters of fundamentals and 5 fiscal years of capital allocation, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.
What is the total market cap of the Aluminum sector?
The 4 Aluminum companies on this page carry $22,643 million of combined market value. Alcoa Corporation is the largest at $11,706 million, about 52% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-07-28.
How is the Aluminum sector performing?
2 of the 4 covered Aluminum companies are beating S&P 500 on Mansfield relative strength. The sector itself is 75.4% ahead of S&P 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-07-28.
How many Aluminum stocks are listed in the US?
This comparison covers 4 listed Aluminum companies in the US, each above the size floor the site applies. The full ranked list is on this page, with reported fundamentals through Jun 2026. Membership is the full industry list — nothing is dropped for having thin data.
Why are some values on this page blank?
A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.
Is this investment advice?
No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
