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
CARGCarGurus, Inc.
Internet Content & Information · $28.85 · beta 1.22
Why now
Internet Content & Information · market cap $2.6b. Down 30% from 52-week high of $41.22 — deep drawdown territory. Revenue growing +14%, comfortably above the S&P median. PEG 0.63 — paying under fair value for the growth rate. 11 sell-side analysts rate this a Buy with a mean 1-yr target of $41.27 (implying +43% upside).
Moat
Net margin 18% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 53% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 156% of net income — earnings translate cleanly into cash.
Risk
Down 30% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.
ZGZillow Group, Inc.
Internet Content & Information · $29.87 · beta 2.02
Why now
Internet Content & Information · market cap $6.7b. Down 61% from 52-week high of $76.32 — deep drawdown territory. Revenue growing +18%, comfortably above the S&P median. PEG 0.92 — paying under fair value for the growth rate. 21 sell-side analysts rate this a Buy with a mean 1-yr target of $47.10 (implying +58% upside).
Moat
Free cash flow runs well ahead of reported net income.
Risk
Trailing P/E 129.9x prices in sustained high growth — any quarter that disappoints triggers sharp re-rating. Down 61% 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.

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 CARG or ZG the better stock?
CARG scores higher: CARG 82.4, ZG 36.9 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 CARG and ZG differ most?
The widest gap is value, where CARG leads by 62 points on the 0–100 pillar scale. CARG also leads quality, while growth is effectively level between them.
How are CARG and ZG 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.
