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
INVAInnoviva, Inc.
Biotechnology · $21.21 · beta 0.38
Why now
Biotechnology · market cap $1.5b. 16% off the 52-week high of $25.15. Revenue growing +19%, comfortably above the S&P median. 5 sell-side analysts publish a mean 1-yr target of $35.00 (implying +65% upside).
Moat
Net margin 81% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 29% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. 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
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 INVA or REGN the better stock?
INVA scores higher: INVA 76.1, 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 INVA and REGN differ most?
The widest gap is value, where INVA leads by 28 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 INVA 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?
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.
