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.

These two disagree on this pair: the Value pillar ranks cheapness against sector peers, while price-vs-fair-value is an absolute read. A name can be the better value in its sector and still the dearer one on cash flows.
The DCF is a cross-check on intrinsic value, separate from the quality-growth score above.

The companies
AYAAya Gold & Silver Inc.
Silver · $27.42 · beta 1.68
Why now
Silver · market cap $3.9b. 11% off the 52-week high of $30.67. Revenue growing +417% — in hypergrowth territory.
Moat
Net margin 33% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 26% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Beta 1.68 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Trailing P/E 36x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates. P/S 11.5x embeds aggressive forward growth — disappointing top-line guidance would compress the multiple hard.
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.

GrowthAYA 50.0 · ERO 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 AYA or ERO the better stock?
AYA scores higher: AYA 70.4, 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 AYA and ERO differ most?
The widest gap is quality, where AYA leads by 18 points on the 0–100 pillar scale. AYA also leads value, while growth is effectively level between them.
How are AYA 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.
