The companies
DUKDuke Energy Corporation
Utilities - Regulated Electric · $116.65 · beta 0.34
Why now
Utilities - Regulated Electric · market cap $91.0b. 13% off the 52-week high of $134.49. 18 sell-side analysts rate this a Buy with a mean 1-yr target of $135.67 (implying +16% upside).
Moat
Net margin 16% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. $91.0b 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
Free cash flow is negative (-$4.3b) — capital raises or debt issuance likely required; dilution / leverage risk.
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.

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 DUK the better stock?
CIG scores higher: CIG 66.6, DUK 48.4 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 DUK differ most?
The widest gap is value, where CIG leads by 42 points on the 0–100 pillar scale. CIG also leads quality, while growth is effectively level between them.
How are CIG and DUK 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.
