CENX — The Aluminium Trade the Market Is Waking Up To
I’ve been watching Century Aluminium for a while now. It came out of my top-down sector screen as the number one ranked name in Basic Materials — clean chart, improving fundamentals, and a macro tailwind that isn’t going away anytime soon.
This is my full breakdown.

Start With the Sector
Before I look at any individual stock I want to know if the sector is working. There’s no point swimming against the tide.
Basic Materials has been one of the stronger performing sectors in 2026. XLB is in an uptrend, institutional money is rotating in, and the aluminium story has a genuine fundamental reason to be running — not just momentum chasing.
The Macro Tailwind
This isn’t a one-trick pony. Several things are happening simultaneously.
Tariffs. The 25% tariffs on aluminium imports imposed in early 2025 changed the game for domestic producers overnight. Foreign competitors became materially more expensive in the US market. That pricing power is feeding directly into CENX margins — gross margin has expanded from 3.6% to 18.3% year on year. That’s a structural shift, not a rounding error.
Strait of Hormuz. Ongoing tensions around the Strait have introduced real supply risk into the global aluminium market. Smelting is energy intensive — Middle East disruption increases production costs for non-US competitors and widens the advantage for domestic producers further.
China overcapacity reversing. For years cheap Chinese metal suppressed aluminium prices globally. That’s changing. Chinese domestic demand is absorbing more of their output, environmental regulations are constraining new capacity, and trade barriers are limiting Western market access. The structural headwind that kept aluminium producers cheap for a decade is easing.
Energy transition demand. An electric vehicle uses roughly double the aluminium of a combustion engine car. Solar panels, grid infrastructure — aluminium is embedded in the energy transition. This underpins why analysts are projecting sustained growth into 2027 and 2028 rather than a single cycle pop.
The tailwinds are stacking.
The Fundamentals
I’m a swing trader not an investor. I just need to know the numbers are moving in the right direction and the fundamentals aren’t a landmine.
Revenue is recovering — $2.53B in 2025, analysts expecting $3.43B in 2026 and $4B by 2027. Forward two year revenue CAGR of 26%.
EPS is the headline number. Normalised EPS goes from $1.11 in 2024 to $2.46 in 2025, then the street is modelling $9.85 for 2026. That’s a serious earnings inflection. Worth noting — the most recent quarterly print of $3.23 includes a one-off $287M asset sale. Strip that out and the underlying number is more modest. Direction of travel is still very much right.
Balance sheet is in better shape than it’s been in years. Net Debt $301M, Net Debt/EBITDA 1.0x. Debt to equity improved from 77% to 42.5%. Cash building — $244M versus $134M six months ago.
Valuation. Trailing PE 16.63x. Forward NTM PE 5.45x. PEG ratio on forward numbers is approximately 0.05. Historical average NTM PE is 26.57x. If earnings deliver and the market re-rates even partially toward that average, the multiple expansion alone is significant. You don’t need perfection for this trade to work.
The Chart

CENX has been in a clean staircase uptrend from October 2025. Higher highs, higher lows, price consistently respecting the 20 EMA. All moving averages fanned out and pointing up — full alignment.
The stock peaked around 685 in late March then pulled back into a tight consolidation. Price is currently sitting around 607, building a flag below prior highs.
The setup is a breakout above 685-690.
A decisive close above that level on volume is the entry trigger. The recent macro noise around tariff negotiations is why the stock has paused. That pause is fine — it’s building a base. When the move comes it’ll be cleaner for it.
Trade plan:
- Entry: break and close above 685 – 690
- Add: first pullback to 20 EMA post breakout
- Stop: below consolidation low, approximately 570 -580
The Risks
Every tailwind here is policy dependent. A trade deal rolling back aluminium tariffs hits CENX hard and fast. Hormuz de-escalation removes a tailwind. US recession reduces industrial demand. Beta is 1.92 — this thing moves.
This is not a stock you hold through a cycle turn. Exit discipline matters more than entry.
Bottom Line
Right stock. Right sector. Right macro moment.
I’m waiting for the breakout. When it comes, I’ll be ready.
