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
Durable high returns
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.
HRMYHarmony Biosciences Holdings, Inc.
Biotechnology · $40.28 · beta 1.01
Why now
Biotechnology · market cap $2.3b. 7% off the 52-week high of $43.49. Revenue growing +24%, comfortably above the S&P median. PEG 0.38 — paying under fair value for the growth rate. 11 sell-side analysts rate this a Buy with a mean 1-yr target of $47.64 (implying +18% upside).
Moat
Net margin 19% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 18% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 196% of net income — earnings translate cleanly into cash.
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.

Where ARGX and HRMY diverge
On the headline score the gap is 11.3 points in favor of HRMY. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

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 HRMY or ARGX the better stock?
HRMY scores higher: HRMY 88.5, ARGX 77.2 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 HRMY and ARGX differ most?
The widest gap is value, where HRMY leads by 27 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 HRMY and ARGX 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.
