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
DORMDorman Products, Inc.
Auto Parts · $120.40 · beta 1.02
Why now
Auto Parts · market cap $3.6b. Down 27% from 52-week high of $164.00 — deep drawdown territory. 8 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $161.63 (implying +34% upside).
Moat
ROE 15% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 98% of net income — earnings translate cleanly into cash.
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.
ORLYO'Reilly Automotive, Inc.
Auto Parts · $86.45 · beta 0.54
Why now
Auto Parts · market cap $69.9b. 17% off the 52-week high of $104.06. 26 sell-side analysts rate this a Buy with a mean 1-yr target of $107.35 (implying +24% upside).
Moat
Net margin 14% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. $69.9b market cap gives the company enough scale to absorb fixed costs that subscale competitors can't, without yet being so large that growth has to come from acquisition.
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.

Where DORM and ORLY diverge
On the headline score the gap is 12.1 points in favor of DORM. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

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 DORM or ORLY the better stock?
DORM scores higher: DORM 60.6, ORLY 48.5 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 DORM and ORLY differ most?
The widest gap is value, where DORM leads by 35 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 DORM and ORLY 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.
