2x versus Kaiser Aluminum Corporation at 26. 0x. On forward P/E, Century Aluminum Company is actually cheaper at 6. 0x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Kaiser Aluminum Corporation wins at 0. 62x versus Newmont Corporation's 0. 82x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

3%, compared to +39. 1% for Kaiser Aluminum Corporation (KALU). Over 10 years, the gap is even starker: CENX returned +732. 6% versus KALU's +126. 5%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

8% yield), NEM (0. 9% yield), AA (0. 6% yield) pay a dividend. CENX, CSTM do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Newmont Corporation (NEM) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

75), 0. 9% yield, +267. 2% 10Y return). Constellium SE (CSTM) carries a higher beta of 1. 85 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (NEM: +267. 2%, CSTM: +502. 6%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

Both stocks operate in the Basic Materials sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: CENX is a small-cap quality compounder stock; AA is a mid-cap deep-value stock; KALU is a small-cap quality compounder stock; CSTM is a small-cap high-growth stock; NEM is a mid-cap high-growth stock. AA, KALU, NEM pay a dividend while CENX, CSTM do not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
