Winner per row is the stronger grade; where grades tie, the better figure breaks it. A true tie or a missing value shows no highlight.

Why this score
Raising its dividend
The companies
ADArray Digital Infrastructure, Inc.
Telecom Services · $33.39 · beta 0.30
Why now
Telecom Services · market cap $2.9b. Down 45% from 52-week high of $60.82 — deep drawdown territory. Revenue growing +58% — in hypergrowth territory. 3 sell-side analysts publish a mean 1-yr target of $43.33 (implying +30% upside).
Moat
ROE 23% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately.
Risk
Free cash flow is negative (-$338m) — capital raises or debt issuance likely required; dilution / leverage risk. Down 45% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. P/S 13.5x embeds aggressive forward growth — disappointing top-line guidance would compress the multiple hard.
TIGOMillicom International Cellular S.A.
Telecom Services · $79.48 · beta 0.90
Why now
Telecom Services · market cap $13.3b. Down 26% from 52-week high of $107.13 — deep drawdown territory. PEG 0.31 — paying under fair value for the growth rate. 8 sell-side analysts rate this a Hold with a mean 1-yr target of $98.39 (implying +24% upside).
Moat
Net margin 23% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 38% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
D/E 4.85 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer.

Where AD and TIGO diverge
On the headline score the gap is 17.6 points in favor of AD. 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 AD or TIGO the better stock?
AD scores higher: AD 67.9, TIGO 50.3 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 AD and TIGO differ most?
The widest gap is value, where AD leads by 43 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 AD and TIGO 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.
