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
ALNYAlnylam Pharmaceuticals, Inc.
Why now
Biotechnology · market cap $31.6b. Down 52% from 52-week high of $495.55 — deep drawdown territory. Revenue growing +65% — in hypergrowth territory. PEG 0.46 — paying under fair value for the growth rate. 26 sell-side analysts rate this a Buy with a mean 1-yr target of $370.20 (implying +57% upside).
Moat
Net margin 20% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 54% — 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
D/E 2.21 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Down 52% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Trailing P/E 41x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
AUPHAurinia Pharmaceuticals Inc.
Why now
Biotechnology · market cap $2.2b. 14% off the 52-week high of $19.25. Revenue growing +20%, comfortably above the S&P median. PEG 0.58 — paying under fair value for the growth rate. 6 sell-side analysts rate this a Buy with a mean 1-yr target of $18.17 (implying +9% upside).
Moat
ROE 51% — 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
Beta 1.40 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. 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.
