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
EROEro Copper Corp.
Copper · $37.61 · beta 1.63
Why now
Copper · market cap $3.9b. 8% off the 52-week high of $40.83. Revenue growing +67% — in hypergrowth territory. PEG 0.71 — paying under fair value for the growth rate. 3 sell-side analysts rate this a Buy with a mean 1-yr target of $40.73 (implying +8% upside).
Moat
Net margin 30% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 31% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Beta 1.63 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Hedge-book exposure — many commodity producers hedge forward production; if the hedge book is concentrated at prices well below spot, the upside the market expects is already locked away.
IAGIAMGOLD Corporation
Gold · $18.80 · beta 2.35
Why now
Gold · market cap $10.7b. Down 24% from 52-week high of $24.87 — deep drawdown territory. Revenue growing +75% — in hypergrowth territory. 6 sell-side analysts rate this a Buy with a mean 1-yr target of $24.33 (implying +29% upside).
Moat
Net margin 31% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 32% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 139% of net income — earnings translate cleanly into cash.
Risk
Beta 2.35 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.

Where ERO and IAG diverge
On the headline score the gap is 7.0 points in favor of IAG. The widest single difference is Value, where IAG leads by 13.9 points.
ValueERO 68.7 · IAG 82.6IAG +13.9
QualityERO 74.9 · IAG 85.3IAG +10.4
GrowthERO 50.0 · IAG 50.0level
Pillars run 0–100. Value is judged against each company's own sector, so a Value 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.
Common questions
Is IAG or ERO the better stock?
IAG scores higher: IAG 70.6, ERO 63.6 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.
Where do IAG and ERO differ most?
The widest gap is value, where IAG leads by 14 points on the 0–100 pillar scale. IAG also leads quality, while growth is effectively level between them.
How are IAG and ERO scored?
Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
How current is this comparison?
The whole universe is re-scored every trading day after the US market close, so the scores and fundamentals here reflect the latest published edition.
