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
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.
TMUST-Mobile US, Inc.
Telecom Services · $148.58 · beta 0.32
Why now
Telecom Services · market cap $159.4b. Down 36% from 52-week high of $230.65 — deep drawdown territory. PEG 0.61 — paying under fair value for the growth rate. 25 sell-side analysts rate this a Buy with a mean 1-yr target of $241.24 (implying +62% upside).
Moat
ROE 19% is above 15% — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 174% of net income — earnings translate cleanly into cash. $159.4b 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
D/E 2.14 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Down 36% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up.

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 TMUS or IDT the better stock?
TMUS scores higher: TMUS 71.9, 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 TMUS and IDT differ most?
The widest gap is value, where TMUS 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 TMUS 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.
