Why now
Health Information Services · market cap $4.0b. Down 71% from 52-week high of $76.51 — deep drawdown territory. Revenue growing +13%, comfortably above the S&P median. PEG 0.59 — paying under fair value for the growth rate. 19 sell-side analysts rate this a Buy with a mean 1-yr target of $24.37 (implying +11% upside).
Moat
Net margin 30% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 21% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 167% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 71% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
DXCMDexCom, Inc.
Why now
Medical Devices · market cap $27.5b. Down 21% from 52-week high of $89.98 — deep drawdown territory. Revenue growing +16%, comfortably above the S&P median. 25 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $85.24 (implying +20% 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 31% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 154% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Beta 1.44 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return. Trailing P/E 31x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
