Growth against the P/E 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
BELFBBel Fuse Inc.
Electronic Components · $244.50 · beta 1.37
Why now
Electronic Components · market cap $3.5b. Down 27% from 52-week high of $335.29 — deep drawdown territory. Revenue growing +25% — in hypergrowth territory. 9 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $333.00 (implying +36% upside).
Moat
Moat signals from the quantitative card are modest — profitability and capital efficiency are middle-of-pack. The thesis here depends on softer factors (switching costs, brand, distribution, regulatory protection) not captured by the quality-growth screen.
Risk
Trailing P/E 59.3x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating.
APHAmphenol Corporation
Electronic Components · $87.24 · beta 1.24
Why now
Electronic Components · market cap $215.1b. Trading near 52-week high of $89.93 — momentum setup, limited technical margin of safety. Revenue growing +52% — in hypergrowth territory. PEG 0.98 — paying under fair value for the growth rate. 19 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $101.66 (implying +17% upside).
Moat
Net margin 18% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 38% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. $215.1b market cap places it among the largest companies in the sector — distribution, R&D, and customer-acquisition costs amortize across a base peers can't replicate.
Risk
Trading within 3% of the 52-week high — limited technical margin of safety; a momentum reversal would test conviction. Trailing P/E 44x 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 APH or BELFB the better stock?
APH scores higher: APH 70.9, BELFB 58.8 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 APH and BELFB differ most?
The widest gap is quality, where APH leads by 13 points on the 0–100 pillar scale. APH leads all three pillars, so the gap is broad rather than a single-measure difference.
How are APH and BELFB 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.
