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.

The companies
FLYFirefly Aerospace Inc.
Aerospace & Defense · $20.00
Why now
Aerospace & Defense · market cap $3.3b. Down 68% from 52-week high of $62.17 — deep drawdown territory. Revenue growing +163% — in hypergrowth territory. 11 sell-side analysts rate this a Buy with a mean 1-yr target of $38.18 (implying +91% 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 (-$326m) — capital raises or debt issuance likely required; dilution / leverage risk. Down 68% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. P/S 11.7x embeds aggressive forward growth — disappointing top-line guidance would compress the multiple hard.
FTAIFTAI Aviation Ltd.
Aerospace & Defense · $169.97 · beta 1.57
Why now
Aerospace & Defense · market cap $17.5b. Down 47% from 52-week high of $323.51 — deep drawdown territory. Revenue growing +45% — in hypergrowth territory. PEG 0.28 — paying under fair value for the growth rate. 10 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $355.60 (implying +109% upside).
Moat
Net margin 16% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent.
Risk
D/E 8.65 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Free cash flow is negative (-$890m) — capital raises or debt issuance likely required; dilution / leverage risk. Down 47% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

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 FTAI or FLY the better stock?
FTAI scores higher: FTAI 69.4, FLY 21.6 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 FTAI and FLY differ most?
The widest gap is value, where FTAI leads by 56 points on the 0–100 pillar scale. FTAI also leads quality, while growth is effectively level between them.
How are FTAI and FLY 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.
