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.
NIONIO Inc.
Auto Manufacturers · $3.58 · beta 0.92
Why now
Auto Manufacturers · market cap $9.0b. Down 53% from 52-week high of $7.54 — deep drawdown territory. Revenue growing +33% — in hypergrowth territory. 24 sell-side analysts rate this a Buy with a mean 1-yr target of $6.32 (implying +77% upside).
Moat
Turnaround / out-of-favor name — GAAP-unprofitable for now, so the durability case is forward-looking: it rests on a recovery (margin normalization, a cyclical upturn or restructuring) or an un-monetized asset (IP / network effects / first-mover position) rather than on current reported results.
Risk
D/E 2.03 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Free cash flow is negative (-$459m) — capital raises or debt issuance likely required; dilution / leverage risk. Currently unprofitable (margin -17.1%) — path to GAAP profitability is the core thesis risk.

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 NIO the better stock?
ATMU scores higher: ATMU 62.8, NIO 13.6 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 ATMU and NIO differ most?
The widest gap is quality, where ATMU leads by 60 points on the 0–100 pillar scale. ATMU also leads value, while growth is effectively level between them.
How are ATMU and NIO 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.
