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
CIGCompanhia Energética de Minas Gerais - CEMIG
Utilities - Regulated Electric · $2.40 · beta 0.06
Why now
Utilities - Regulated Electric · market cap $6.9b. 13% off the 52-week high of $2.76. PEG 0.33 — paying under fair value for the growth rate. 3 sell-side analysts publish a mean 1-yr target of $2.05 (implying -14% upside).
Moat
ROE 16% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Dividend payout 79% of earnings on a 6.2% yield — distribution coverage is thin; one earnings stumble could force a dividend cut.
NRGNRG Energy, Inc.
Utilities - Independent Power Producers · $107.97 · beta 1.16
Why now
Utilities - Independent Power Producers · market cap $22.7b. Down 43% from 52-week high of $189.96 — deep drawdown territory. PEG 0.41 — paying under fair value for the growth rate. 16 sell-side analysts rate this a Buy with a mean 1-yr target of $185.50 (implying +72% upside).
Moat
ROE 24% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
D/E 4.83 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Down 43% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Net margin 2.6% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first.

Where CIG and NRG diverge
On the headline score the gap is 17.3 points in favor of CIG. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

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 CIG or NRG the better stock?
CIG scores higher: CIG 66.6, NRG 49.3 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 CIG and NRG differ most?
The widest gap is value, where CIG leads by 48 points on the 0–100 pillar scale. Neither name sweeps: they trade the lead across the three pillars, so the comparison is a trade-off rather than one being better on every measure.
How are CIG and NRG 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.
