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
ALLYAlly Financial Inc.
Credit Services · $37.59 · beta 1.10
Why now
Credit Services · market cap $11.4b. Down 21% from 52-week high of $47.29 — deep drawdown territory. PEG 0.27 — paying under fair value for the growth rate. 18 sell-side analysts rate this a Buy with a mean 1-yr target of $49.73 (implying +32% 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.
Risk
Balance-sheet financial — book value, net interest margin, and credit loss provisions are the lever points; a rates regime change or a deterioration in the loan book moves the stock more than EPS does.
NNINelnet, Inc.
Credit Services · $125.26 · beta 0.77
Why now
Credit Services · market cap $4.5b. 13% off the 52-week high of $144.38. Revenue growing +16%, comfortably above the S&P median.
Moat
Net margin 20% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. FCF converts 120% of net income — earnings translate cleanly into cash.
Risk
ROE 7% is below the long-run sustainable threshold of ~10% — capital efficiency would need to improve for the equity base to compound at the market rate. Balance-sheet financial — book value, net interest margin, and credit loss provisions are the lever points; a rates regime change or a deterioration in the loan book moves the stock more than EPS does.

Common questions
Is ALLY or NNI the better stock?
ALLY scores higher: ALLY 82.0, NNI 75.0 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.
How are ALLY and NNI 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?
