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.

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.
IDTIDT Corporation
Telecom Services · $81.49 · beta 0.60
Why now
Telecom Services · market cap $2.0b. Trading near 52-week high of $82.31 — momentum setup, limited technical margin of safety.
Moat
ROE 26% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which.
Risk
Trading within 1% of the 52-week high — limited technical margin of safety; a momentum reversal would test conviction.

Where AD and IDT diverge
On the headline score the gap is 25.6 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 IDT the better stock?
AD scores higher: AD 67.9, IDT 42.3 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 IDT differ most?
The widest gap is value, where AD leads by 56 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 IDT 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.
