Why this score
Durable high returns
The companies
HIIHuntington Ingalls Industries, Inc.
Aerospace & Defense · $264.80 · beta 0.21
Why now
Aerospace & Defense · market cap $10.4b. Down 42% from 52-week high of $460.00 — deep drawdown territory. Revenue growing +14%, comfortably above the S&P median. PEG 0.81 — paying under fair value for the growth rate. 12 sell-side analysts rate this a Buy with a mean 1-yr target of $363.00 (implying +37% upside).
Moat
ROE 12% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere.
Risk
Free cash flow is negative (-$85m) — capital raises or debt issuance likely required; dilution / leverage risk. Down 42% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
TDGTransDigm Group Incorporated
Aerospace & Defense · $1,107.99 · beta 0.94
Why now
Aerospace & Defense · market cap $61.2b. Down 24% from 52-week high of $1463.03 — deep drawdown territory. Revenue growing +17%, comfortably above the S&P median. 20 sell-side analysts rate this a Buy with a mean 1-yr target of $1,448 (implying +31% upside).
Moat
Net margin 21% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. $61.2b 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
Trailing P/E 34x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

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 TDG or HII the better stock?
TDG scores higher: TDG 74.9, HII 61.3 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 TDG and HII differ most?
The widest gap is quality, where TDG leads by 27 points on the 0–100 pillar scale. TDG leads all three pillars, so the gap is broad rather than a single-measure difference.
How are TDG and HII 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.
