Verdict: Side-by-side breakdown using the Bull Rankings model. ARGX scored 77.2, ONC scored 67.8 — ARGX leads.
Compare another set
Different reporting periods. ONC's fundamentals are as of June 2026, but ARGX's are as of December 2025 — a 6-month gap. Growth, margin and valuation figures below therefore describe different windows and aren't strictly like-for-like.

Side by side · every name on one set of axes
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.

These two disagree on this pair: the Value pillar ranks cheapness against sector peers, while price-vs-fair-value is an absolute read. A name can be the better value in its sector and still the dearer one on cash flows.
The DCF is a cross-check on intrinsic value, separate from the quality-growth score above.

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.
ONCBeOne Medicines AG
Biotechnology · $354.47 · beta 0.61
Why now
Biotechnology · market cap $40.3b. 8% off the 52-week high of $385.22. Revenue growing +34% — in hypergrowth territory. PEG 0.74 — paying under fair value for the growth rate. 27 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $435.53 (implying +23% upside).
Moat
ROE 13% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. Free cash flow runs well ahead of reported net income, mostly because of stock-based pay ($525m) — a real cost to shareholders, paid in shares rather than cash. Pharma moat is patent runway + pipeline depth — a single approved molecule funds the next generation of bets. Late-stage trials carry binary readouts that swing valuation 30%+.
Risk
Trailing P/E 63.4x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Reimbursement risk — even an approved drug can fail commercially if payors don't reimburse; pricing pressure from Medicare and large PBMs has been accelerating since 2024.

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 ONC the better stock?
ARGX scores higher: ARGX 77.2, ONC 67.8 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 ARGX and ONC differ most?
The widest gap is quality, where ARGX leads by 12 points on the 0–100 pillar scale. ARGX leads all three pillars, so the gap is broad rather than a single-measure difference.
How are ARGX and ONC 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.
