The companies
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.
QSQuantumScape Corporation
Auto Parts · $4.58 · beta 2.84
Why now
Auto Parts · market cap $2.8b. Down 76% from 52-week high of $19.07 — deep drawdown territory. 8 sell-side analysts rate this a Hold with a mean 1-yr target of $6.66 (implying +45% upside).
Moat
Higher-variance name — the moat signals on the quantitative card are modest, so the durability case rests on execution (turning current growth into durable earnings power) or an un-monetized asset (IP / network effects / first-mover position) rather than an entrenched competitive position.
Risk
Free cash flow is negative (-$273m) — capital raises or debt issuance likely required; dilution / leverage risk. Down 76% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.84 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.

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 QS the better stock?
ATMU scores higher: ATMU 62.8, QS 10.4 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 QS differ most?
The widest gap is value, where ATMU leads by 59 points on the 0–100 pillar scale. ATMU leads all three pillars, so the gap is broad rather than a single-measure difference.
How are ATMU and QS 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.
