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.

The companies
HALOHalozyme Therapeutics, Inc.
Why now
Biotechnology · market cap $12.3b. Trading near 52-week high of $108.49 — momentum setup, limited technical margin of safety. Revenue growing +41% — in hypergrowth territory. 9 sell-side analysts rate this a Buy with a mean 1-yr target of $99.56 (implying -8% upside).
Moat
Net margin 25% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. FCF converts 195% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined. 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
Trading within 0% of the 52-week high — limited technical margin of safety; a momentum reversal would test conviction. Trailing P/E 32x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates. 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.
JAZZJazz Pharmaceuticals plc
Why now
Biotechnology · market cap $16.5b. 4% off the 52-week high of $265.05. Revenue growing +13%, comfortably above the S&P median. PEG 0.96 — paying under fair value for the growth rate. 20 sell-side analysts rate this a Buy with a mean 1-yr target of $281.35 (implying +11% upside).
Moat
Net margin 20% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 20% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 169% 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.
