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
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.

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.

Where NRG and CIG 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.
