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
Durable high returns
The companies
PWRQuanta Services, Inc.
Engineering & Construction · $705.94 · beta 1.27
Why now
Engineering & Construction · market cap $106.1b. 10% off the 52-week high of $788.75. Revenue growing +26% — in hypergrowth territory. 29 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $766.01 (implying +9% upside).
Moat
ROE 14% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. FCF converts 180% of net income — earnings translate cleanly into cash. $106.1b market cap gives the company enough scale to absorb fixed costs that subscale competitors can't, without yet being so large that growth has to come from acquisition.
Risk
Trailing P/E 78.5x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Net margin 4.0% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first.
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.

On the headline score the gap is 22.9 points in favor of STRL. The widest single difference is Value, where STRL leads by 27.7 points.

QualityPWR 61.1 · STRL 84.4STRL +23.3
GrowthPWR 94.6 · STRL 96.0level
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 PWR the better stock?
STRL scores higher: STRL 75.4, PWR 52.5 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 PWR differ most?
The widest gap is value, where STRL leads by 28 points on the 0–100 pillar scale. STRL also leads quality, while growth is effectively level between them.
How are STRL and PWR 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.
