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.

Why this score
  • Raising its dividend
ESEESCO Technologies Inc.
Scientific & Technical Instruments · $257.83 · beta 1.05
Why now
Scientific & Technical Instruments · market cap $6.7b. Down 29% from 52-week high of $362.15 — deep drawdown territory. Revenue growing +27% — in hypergrowth territory. 4 sell-side analysts publish a mean 1-yr target of $390.75 (implying +52% upside).
Moat
Net margin 24% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 19% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Trailing P/E 48x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
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 41x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

Where ESE and MKSI diverge

On the headline score the gap is 18.1 points in favor of ESE. The widest single difference is Value, where ESE leads by 31.2 points.

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 ESE or MKSI the better stock?

ESE scores higher: ESE 72.9, MKSI 54.8 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 ESE and MKSI differ most?

The widest gap is value, where ESE leads by 31 points on the 0–100 pillar scale. ESE also leads quality, while growth is effectively level between them.

How are ESE and MKSI 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.
