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
BIRKBirkenstock Holding plc
Footwear & Accessories · $33.65 · beta 1.30
Why now
Footwear & Accessories · market cap $5.6b. Down 34% from 52-week high of $50.73 — deep drawdown territory. Revenue growing +16%, comfortably above the S&P median. PEG 0.95 — paying under fair value for the growth rate. 20 sell-side analysts rate this a Buy with a mean 1-yr target of $50.16 (implying +49% upside).
Moat
Net margin 15% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 12% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere.
Risk
Down 34% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
ZGNErmenegildo Zegna N.V.
Apparel Manufacturing · $12.68 · beta 0.91
Why now
Apparel Manufacturing · market cap $3.4b. Down 21% from 52-week high of $15.95 — deep drawdown territory. 13 sell-side analysts rate this a Buy with a mean 1-yr target of $14.41 (implying +14% upside).
Moat
Free cash flow runs well ahead of reported net income, mostly because of depreciation and amortization ($287m) — non-cash charges that hold down reported earnings while cash generation stays strong.
Risk
Trailing P/E 36x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

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 BIRK or ZGN the better stock?
BIRK scores higher: BIRK 68.5, ZGN 37.4 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 BIRK and ZGN differ most?
The widest gap is growth, where BIRK leads by 52 points on the 0–100 pillar scale. BIRK also leads value, while quality is effectively level between them.
How are BIRK and ZGN 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.
