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.

Durable high returns
The companies
MTZMasTec, Inc.
Engineering & Construction · $212.65 · beta 1.84
Why now
Engineering & Construction · market cap $17.1b. Down 52% from 52-week high of $441.43 — deep drawdown territory. Revenue growing +16%, comfortably above the S&P median. PEG 0.65 — paying under fair value for the growth rate. 20 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $392.80 (implying +85% upside).
Moat
ROE 16% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Down 52% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.84 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 34x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.
STRLSterling Infrastructure, Inc.
Engineering & Construction · $513.00 · beta 1.86
Why now
Engineering & Construction · market cap $15.7b. Down 49% from 52-week high of $1005.68 — deep drawdown territory. Revenue growing +61% — in hypergrowth territory. PEG 0.64 — paying under fair value for the growth rate. 7 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $836.57 (implying +63% upside).
Moat
Net margin 13% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 32% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 112% of net income — earnings translate cleanly into cash.
Risk
Down 49% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.86 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 37x sits well above the S&P median (~20x) — multiple compression is a real risk if revenue growth decelerates.

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 STRL or MTZ the better stock?
STRL scores higher: STRL 75.4, MTZ 59.9 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 STRL and MTZ differ most?
The widest gap is quality, where STRL leads by 30 points on the 0–100 pillar scale. STRL leads all three pillars, so the gap is broad rather than a single-measure difference.
How are STRL and MTZ 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.
How current is this comparison?
The whole universe is re-scored every trading day after the US market close, so the scores and fundamentals here reflect the latest published edition.
