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.

Why this score
Diluting shareholders
The companies
ARGXargenx SE
Biotechnology · $825.03 · beta -0.04
Why now
Biotechnology · market cap $51.9b. Down 23% from 52-week high of $1072.75 — deep drawdown territory. Revenue growing +90% — in hypergrowth territory. 23 sell-side analysts rate this a Buy with a mean 1-yr target of $1,154 (implying +40% upside).
Moat
Net margin 31% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 18% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. $51.9b 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 31x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates. P/S 12.5x embeds aggressive forward growth — disappointing top-line guidance would compress the multiple hard. Trial-readout binary — late-stage clinical trials carry approve/reject outcomes that swing valuation 30%+; the equity is effectively a portfolio of these binary events, not a steady cash-flow business.
REGNRegeneron Pharmaceuticals, Inc.
Biotechnology · $746.54 · beta 0.15
Why now
Biotechnology · market cap $76.9b. 13% off the 52-week high of $859.34. 26 sell-side analysts rate this a Buy with a mean 1-yr target of $859.04 (implying +15% upside).
Moat
Net margin 28% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 14% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. $76.9b 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
Trial-readout binary — late-stage clinical trials carry approve/reject outcomes that swing valuation 30%+; the equity is effectively a portfolio of these binary events, not a steady cash-flow business.

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 ARGX or REGN the better stock?
ARGX scores higher: ARGX 77.2, REGN 68.1 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 ARGX and REGN differ most?
The widest gap is growth, where ARGX leads by 22 points on the 0–100 pillar scale. ARGX also leads quality, while value is effectively level between them.
How are ARGX and REGN 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?
