The companies
CDNACareDx, Inc.
Why now
Diagnostics & Research · market cap $2.0b. 6% off the 52-week high of $40.47. Revenue growing +34% — in hypergrowth territory. 5 sell-side analysts rate this a Buy with a mean 1-yr target of $35.40 (implying -7% upside).
Moat
Net margin 24% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 26% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Beta 2.43 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
RMDResMed Inc.
Why now
Medical Instruments & Supplies · market cap $30.3b. Down 29% from 52-week high of $293.81 — deep drawdown territory. Revenue growing +10%, comfortably above the S&P median. 15 sell-side analysts rate this a Buy with a mean 1-yr target of $248.60 (implying +19% upside).
Moat
Net margin 27% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 23% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 115% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Mature compounder — the risk is paying up for quality at a moment when growth is decelerating. Watch for sequential revenue + margin trends; the inflection from "compounder" to "ex-compounder" is hard to spot until the multiple already started compressing.
