The companies
ADMAADMA Biologics, Inc.
Why now
Biotechnology · market cap $2.1b. Down 56% from 52-week high of $20.46 — deep drawdown territory. Revenue growing +20%, comfortably above the S&P median. PEG 0.67 — paying under fair value for the growth rate. 5 sell-side analysts publish a mean 1-yr target of $17.60 (implying +97% upside).
Moat
Net margin 32% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma. ROE 42% — 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
Down 56% 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.
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.
