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.

The companies
CAICaris Life Sciences, Inc.
Why now
Biotechnology · market cap $7.4b. Down 35% from 52-week high of $40.40 — deep drawdown territory. Revenue growing +85% — in hypergrowth territory. PEG 0.02 — paying under fair value for the growth rate. 12 sell-side analysts rate this a Buy with a mean 1-yr target of $27.00 (implying +3% upside).
Moat
ROE 18% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 118% 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
Down 35% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. 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.
EXELExelixis, Inc.
Why now
Biotechnology · market cap $13.4b. 6% off the 52-week high of $57.57. 17 sell-side analysts rate this a Buy with a mean 1-yr target of $53.00 (implying -2% upside).
Moat
Net margin 35% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 47% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 136% 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.

Where CAI and EXEL diverge
On the headline score the gap is 5.6 points in favor of EXEL. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

- ValueCAI 72.3 · EXEL 52.5CAI +19.8

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.
