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.

CGNXCognex Corporation
Scientific & Technical Instruments · $62.92 · beta 1.48
Why now
Scientific & Technical Instruments · market cap $10.6b. 14% off the 52-week high of $72.88. 19 sell-side analysts rate this a Buy with a mean 1-yr target of $79.11 (implying +26% upside).
Moat
Net margin 16% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 11% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 153% of net income — earnings translate cleanly into cash.
Risk
Trailing P/E 60.5x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Beta 1.48 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.
MKSIMKS Inc.
Scientific & Technical Instruments · $264.50 · beta 2.02
Why now
Scientific & Technical Instruments · market cap $17.9b. Down 41% from 52-week high of $447.62 — deep drawdown territory. Revenue growing +16%, comfortably above the S&P median. 14 sell-side analysts publish a mean 1-yr target of $410.86 (implying +55% upside).
Moat
ROE 15% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 103% of net income — earnings translate cleanly into cash.
Risk
Down 41% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 2.02 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 42x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

Where CGNX and MKSI diverge

On the headline score the gap is 7.5 points in favor of MKSI. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

Pillars run 0–100. Value is judged against each company's own sector, so a Value 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.

Common questions

Is MKSI or CGNX the better stock?

MKSI scores higher: MKSI 54.8, CGNX 47.3 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.

Where do MKSI and CGNX differ most?

The widest gap is quality, where CGNX leads by 20 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.

How are MKSI and CGNX scored?

Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
