Growth against the P/S 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.

CARAvis Budget Group, Inc.
Rental & Leasing Services · $105.98 · beta 2.11
Why now
Rental & Leasing Services · market cap $3.7b. Down 87% from 52-week high of $847.70 — deep drawdown territory. PEG 0.17 — paying under fair value for the growth rate. 7 sell-side analysts rate this a Hold with a mean 1-yr target of $122.86 (implying +16% 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
Free cash flow is negative (-$11.4b) — capital raises or debt issuance likely required; dilution / leverage risk. Currently unprofitable (margin -5.4%) — path to GAAP profitability is the core thesis risk. Down 87% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
AERAerCap Holdings N.V.
Rental & Leasing Services · $144.72 · beta 0.98
Why now
Rental & Leasing Services · market cap $22.7b. 9% off the 52-week high of $158.81. PEG 0.80 — paying under fair value for the growth rate. 10 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $179.30 (implying +24% upside).
Moat
Net margin 38% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 19% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
D/E 2.33 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Free cash flow is negative (-$307m) — capital raises or debt issuance likely required; dilution / leverage risk.

Where CAR and AER diverge
On the headline score the gap is 51.9 points in favor of AER. The widest single difference is Value, where AER leads by 61.2 points.
ValueCAR 5.0 · AER 66.2AER +61.2
GrowthCAR 14.4 · AER 62.9AER +48.5
QualityCAR 19.8 · AER 60.4AER +40.6
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 AER or CAR the better stock?
AER scores higher: AER 63.1, CAR 11.2 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 AER and CAR differ most?
The widest gap is value, where AER leads by 61 points on the 0–100 pillar scale. AER leads all three pillars, so the gap is broad rather than a single-measure difference.
How are AER and CAR 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.
