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
AZOAutoZone, Inc.
Auto Parts · $2,939.85 · beta 0.40
Why now
Auto Parts · market cap $47.5b. Down 29% from 52-week high of $4146.42 — deep drawdown territory. 23 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $3,720 (implying +27% upside).
Moat
Net margin 13% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent.
Risk
Mature compounder — the risk is paying up for quality at a moment when growth is decelerating. Watch for sequential revenue + margin trends; the inflection from "compounder" to "ex-compounder" is hard to spot until the multiple already started compressing.
ATMUAtmus Filtration Technologies Inc.
Auto Parts · $42.81 · beta 1.20
Why now
Auto Parts · market cap $3.5b. Down 36% from 52-week high of $66.50 — deep drawdown territory. Revenue growing +13%, comfortably above the S&P median. 5 sell-side analysts rate this a Buy with a mean 1-yr target of $62.60 (implying +46% upside).
Moat
ROE 47% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
D/E 2.32 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Down 36% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

Where AZO and ATMU diverge

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 ATMU or AZO the better stock?
ATMU scores higher: ATMU 62.8, AZO 46.4 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 ATMU and AZO differ most?
The widest gap is value, where ATMU leads by 40 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.
How are ATMU and AZO 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.
