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.

The companies
BSXBoston Scientific Corporation
Why now
Medical Devices · market cap $73.0b. Down 54% from 52-week high of $109.50 — deep drawdown territory. Revenue growing +14%, comfortably above the S&P median. PEG 0.75 — paying under fair value for the growth rate. 29 sell-side analysts rate this a Buy with a mean 1-yr target of $62.69 (implying +24% upside).
Moat
Net margin 17% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 15% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 99% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Down 54% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
RMDResMed Inc.
Why now
Medical Instruments & Supplies · market cap $33.0b. Down 22% from 52-week high of $293.81 — deep drawdown territory. 16 sell-side analysts rate this a Buy with a mean 1-yr target of $245.50 (implying +7% 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 108% 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.
Verdict — model-derived comparison
RMD leads BSX by 2.9 points (81.0 to 78.1), its sharpest advantage coming in D/E (grade B+). A contrarian could still prefer BSX, which trades about 12% below our DCF fair value — a margin of safety the score doesn't reward. Note they play different roles — BSX screens as value, RMD screens as growth — so the model rewards different traits for each.
Our AI analyst is busy right now, so this verdict is drawn directly from the pillars, grades and DCF above.

Where BSX and RMD diverge
On the headline score the gap is 2.9 points in favor of RMD. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

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.
