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
CSTMConstellium SE
Why now
Aluminum · market cap $3.7b. Down 27% from 52-week high of $36.99 — deep drawdown territory. Revenue growing +20%, comfortably above the S&P median. PEG 0.40 — paying under fair value for the growth rate. 5 sell-side analysts publish a mean 1-yr target of $38.28 (implying +42% upside).
Moat
ROE 39% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Beta 1.57 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Net margin 4.9% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first.
HMYHarmony Gold Mining Company Ltd
Why now
Metals & Mining · market cap $221.0b. Down 100% from 52-week high of $42888.00 — deep drawdown territory. Revenue growing +21%, comfortably above the S&P median.
Moat
Net margin 20% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 33% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. $221.0b market cap places it among the largest companies in the sector — distribution, R&D, and customer-acquisition costs amortize across a base peers can't replicate.
Risk
Down 100% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.36 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Jurisdictional + permitting risk — mining and extraction operations concentrate exposure to political stability, royalty regimes, and environmental review timelines that can stall production for years.

- GrowthCSTM 42.4 · HMY 50.0HMY +7.6
- ValueCSTM 80.2 · HMY 86.7HMY +6.5
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.
