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
OSISOSI Systems, Inc.
Electronic Components · $194.91 · beta 1.21
Why now
Electronic Components · market cap $3.1b. Down 37% from 52-week high of $311.72 — deep drawdown territory. 7 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $273.29 (implying +40% upside).
Moat
ROE 19% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 159% of net income, helped by cash released from working capital ($46m) that doesn't repeat every year.
Risk
Down 37% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
BELFABel Fuse Inc.
Electronic Components · $195.38 · beta 1.37
Why now
Electronic Components · market cap $2.8b. Down 33% from 52-week high of $293.51 — deep drawdown territory. Revenue growing +25% — in hypergrowth territory.
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
Down 33% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Trailing P/E 48x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

Where OSIS and BELFA diverge

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 BELFA or OSIS the better stock?
BELFA scores higher: BELFA 60.2, OSIS 58.5 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 BELFA and OSIS differ most?
The widest gap is growth, where BELFA leads by 18 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.
How are BELFA and OSIS 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.
