The companies
ISRGIntuitive Surgical, Inc.
Why now
Medical Instruments & Supplies · market cap $126.5b. Down 42% from 52-week high of $603.88 — deep drawdown territory. Revenue growing +21%, comfortably above the S&P median. 29 sell-side analysts rate this a Buy with a mean 1-yr target of $484.60 (implying +37% upside).
Moat
Net margin 28% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 17% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 103% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 42% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.46 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 40x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

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.
