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
GSKGSK plc
Why now
Drug Manufacturers - General · market cap $103.7b. 16% off the 52-week high of $61.70. 8 sell-side analysts rate this a Hold with a mean 1-yr target of $58.08 (implying +12% 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 39% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 111% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
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.
NBIXNeurocrine Biosciences, Inc.
Why now
Drug Manufacturers - Specialty & Generic · market cap $15.6b. 18% off the 52-week high of $186.12. Revenue growing +34% — in hypergrowth territory. PEG 0.45 — paying under fair value for the growth rate. 27 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $211.57 (implying +38% upside).
Moat
Net margin 21% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 19% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 123% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
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 against sector peers, so a 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.
