Side by side · every name on one set of axes
Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

The companies
CENXCentury Aluminum Company
Why now
Aluminum · market cap $4.3b. Down 38% from 52-week high of $70.43 — deep drawdown territory. PEG 0.06 — paying under fair value for the growth rate. 4 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $70.00 (implying +59% upside).
Moat
Net margin 23% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 43% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Down 38% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.00 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
FSMFortuna Mining Corp.
Why now
Gold · market cap $3.6b. 13% off the 52-week high of $13.85. Revenue growing +40% — in hypergrowth territory. PEG 0.44 — paying under fair value for the growth rate.
Moat
Net margin 33% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 18% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 197% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Beta 2.12 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Production-cost sensitivity — top-quartile cost producers generate cash through the cycle while marginal producers burn it; watch the cost-per-unit trend, not just headline revenue.

Pillars run 0–100 against sector peers, so a score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
